Working on my new to me 85
Car sat for 10 years. Attached are some pics of the old fuel tank and fuel pump.
I am installing new tank. Rebuilt the the fuel rail and installed new injectors as well as new fuel regulator. All is still off the car.
Putting the new tank in soon. Have some other stuff to do before. Maybe new rear springs.
Few ?’s
New sending unit and New Delphi pump.
Does it look like I have the new parts installed correctly? No instructions with it and different than the factory one.
what are the extra parts for I have left over ? Other models ? I know the white pieces are soem
type of hose or wire holders.
The small black round rubber piece, is that for the return line ?



Black rubber piece on return line ?



There was a rubber piece that looks like it goes on the top of the pump where the wire connection goes. Is that the right place for it ?

 

Old pump and tank !
Seen better days !

 

The white clamps go around the little rubber jumper hose from the pickup to the fuel pump. The black part looks like it goes on the bottom of the pump to hold the sock on perhaps?
It's been a while (and hopefully will keep it that way) since I replaced my in tank fuel pump.

 

Thanks. Any idea if I need the off white bigger piece ? Can not figure out where that goes.
I tried putting the black rubber on the bottom but couldn't get the strainer on all the way with it there.

 

Trial and error at this point. I looked in the FSM and FPM for a diagram and nothing that illustrates those particular parts since they were probably sold as an entire assembly.

 

Ok Thanks
I checked all the books I have and nothing referred to them as well.

 

The big off white plastic part is not used in your application. The two bright white parts are hose clamps. The round black rubber bumper donut piece is not used in our application.

The left over black rubber piece with the opening that looks like the keyway in an old door lock that takes a skeleton key and has the two slots on each side goes on the bottom of the fuel pump before you put it into the hanger assembly. You will notice the shapes don't match between the two pieces. You will have to file and deburr the metal opening in the hanger to fit the rubber piece and or trim the rubber piece to fit the opening in the hanger.


1989 1LE

I got the picture above from this thread below.

1LE Gas Tank - from the 1989 Archive

If you are interested in the larger 1LE fuel pump strainer it is a Delphi FS0029. You must verify your replacement fuel tank is made inside like a 1LE tank. All 3rd gen fuel tanks even in V6 cars are 1LE style starting somewhere in late 1989 or early 1990. The last replacement fuel tank I installed was 1LE style inside and would have took the bigger strainer no problem. I didn't install one though because I didn't want to wait to order it and I already had everything ready to put the car back together so I left it with the normal size strainer. It runs just fine with the normal strainer.

 

Or maybe that black rubber piece that goes between the fuel pump and hanger goes in upside down from the way I think it goes on.

These are aftermarket parts so who knows. LoL

 

Ok. Thanks for the help.

 

Does the pump need the rubber piece on the bottom ? Is it to keep fro having metal on metal ?

 

General Motors would kill The Last Unicorn on Earth if it meant they could save a penny per car.



GM put that rubber grommet between the hanger and fuel pump for some reason. Do you absolutely have to have it there? Probably not but it looks like you are about 90% of the way there to having it fit into the bottom of the hanger. Some round and flat files or a Dremel tool with a stone or burr, then deburr the opening you worked on in the hanger and that grommet will fit.

 

Ok. Thanks.
I’ll give it a whirl !

 

OK I think I got this figured out now why everything doesn't fit just perfect with your fuel pump and fuel pump hanger/sending unit assembly.

There are two factory electric fuel pumps and two factory fuel pump hanger/sending unit assemblies for our fuel injected 3rd gens.

Note: I'm only talking about TBI and TPI cars. I'm not talking about earlier carb cars with an in tank electric helper pump, or crossfire injected cars, or the little odd ball differences between 1LE and not 1LE cars.

The aftermarket makes fuel pump kits to fit TBI cars with the factory TBI fuel pump hanger/sending unit assembly and makes aftermarket fuel pump kits to fit TPI cars with the factory TPI fuel pump hanger/sending unit assembly.

The aftermarket only makes a fuel pump hanger/sending unit assemblies to fit TBI cars. They don't make one to fit TPI cars anymore.

The end of the fuel pumps and the rubber isolators are different between TBI and TPI. The rubber isolators won't swap between TBI and TPI fuel pumps. The aftermarket TBI fuel pump and TBI isolator will fit into the aftermarket fuel pump hanger/sending unit assembly because it made with the TBI size and shape opening on the bottom bracket that the fuel pump sits in.

There was a metric f*ck ton more TBI cars made than TPI cars made. The aftermarket doesn't want to make two versions of the fuel pump hanger/sending unit assembly. So they just makes the far more popular one with the TBI style opening in the bottom bracket. They should make the opening a combination of the TBI & TPI style opening so the bottom fuel pump retaining bracket will fit both styles.

The companies that make the fuel pumps are not the same companies that make the fuel pump hanger/sending units

 

Generic Delphi Fuel Pump Instructions. The "Goes Here" arrow was already there in the picture I stole online. That is where the fuel pump goes. LoL

Delphi FE0115 TBI fuel pump with included accessories. This kit comes with the both rubber isolators that fit both styles of fuel pumps.

Delphi FE0115 TBI fuel pump with included accessories. These fuel pumps kits come with accessories that aren't used in some applications. These fuel pump kits fit other cars beside 3rd gen Camaros and Firebirds.

Delphi FE0115 TBI Fuel Pump. 22 GPH @13 PSI

Delphi FE0115 TBI Fuel Pump. Notice it doesn't have the two protruding tabs that fit into the rubber isolator that doesn't fit into the lower mounting bracket of your aftermarket fuel pump hanger/sending unit.

Same just different picture.

 

In your application you won't use the Pulsator Assembly or the Rubber Bumper that goes below the Pulsator Assembly. You will use the Rubber Coupling Fuel Hose instead. Also I wouldn't trust that the Chinese actually supplied real "Submersible Rated" high pressure fuel injection hose in the installation kit no further than I can pick up your car and throw it.

In your application you won't use the big white plastic piece or the little round Rubber Bumper that comes in the installation kit. Also you are only going to use 1 of those two big rubber O-rings to seal the fuel hanger to your gas tank.

These fuel pumps fit more cars than just our third gens. Not all parts will be used in our applications.

Delphi FE0110 TPI Fuel Pump


The proper Rubber Isolator that fits the bottom of the TPI fuel pump doesn't fit into the bottom Mounting Bracket of your aftermarket fuel hanger. You have to modify the opening in the bracket to fit the Rubber Isolator.

 

Also looks like if a guy filed off those two protruding tabs on the bottom of the TPI fuel pump then the TBI rubber isolator would fit on it just fine and then fit into the normal opening in the bottom mounting bracket on the aftermarket hangers. But the Delphi FE0110 TPI pump doesn't come with the TBI rubber isolator.

All the aftermarket hangers I ever had comes with the correct rubber isolator to fit it.

By the time you get an aftermarket tank, aftermarket fuel pump kit, and an aftermarket hanger/sender you normally have a handful of leftover and duplicate parts.

 

Airwolfe you are awesome ! I searched for the info you provided but struck out. I will check the fuel line they provided. Any idea how to check if it can be submersed in fuel ?
Do I need to modify the bracket or just leave the rubber off ? I believe the one I pulled out does not have the rubber isolator on it but most of it is in pieces so it is hard to tell.

So these 2 circled aren’t used in my application is what I gather from the information.

 

The little round black donut rubber bumper that you put on the end of the fuel return tube, the big white plastic piece, and one of the two big O-rings aren't used in your application.

The rubber isolator that goes between the pump and lower mounting bracket on your hanger won't fit your hanger.

You can at your discretion either leave it off, modify the opening in the lower mounting bracket so it fits, find the proper rubber isolator that should have came with your hanger and cut the protruding tabs off the bottom of the fuel pump so the rubber isolator will fit it and go right into the hanger, or go to the parts store and buy the Delphi FE0115 fuel pump and steal the rubber isolator out of it then return it and play dumb. The idiot behind the parts counter ain't going to know any better or care. The next guy that buys it will be screwed when he goes to install it but that is what always happens to me at the parts store when I get screwed buying a part. LoL

As far as the short piece of fuel hose the Chinese slave kids put in the box actually being real "Submersible Rated" high pressure fuel injection hose you roll the dice and take your chances or go to the parts store and make sure you buy the correct hose. You know how hard it was to take all this stuff apart and to put back together again.

Do you really want to have to do it all over again anytime soon?

 

The pump came with both rubber isolators. I must not have gotten a picture of it. I guess simplest thing to do is cut the tabs off the pump
What about the big rubber sleeve, not the one on the pump ? Do i have that in the correct spot covering the hose and electrical connector ?
On the TPI Pump do i have to worry about covering up the rubber circled below ?

 

Oh so you have the correct rubber isolator that will fit into the opening on the lower bracket?

The big rubber piece you have on top of the fuel pump looks OK. Does it fit tight? I can't see it hurting anything being there. I don't ever remember any of the pumps I use having it but it's been awhile. And don't forget to put both clamps on the short section of fuel hose too.

You going to have to mock things up and see how everything fits together and make some judgement calls on how to precede with things.

This is what I use. It ain't cheap for this type of hose. The local parts store probably has something like it. But it has to be fuel Submersible rated. Or just trust the Chinese slave kids did the right thing.

Racetronix - Fuel Hose, 3/8" ID FKM/Aramid Fiber SAE30R10 In-tank Submersible E85

 

ok. The big rubber around the electrical connector is not tight so I’ll leave that off.
I don’t like the plastic clamps. Already broke one trying to tighten it. So regular hose clamps will be used.
I will stop at local store and ask them for some hose.

I have the correct rubber isolator for the sending unit. Just doesn’t fit bc of the tabs.

any issues with covering the black piece on the bottom of the pump ?

Thnaks

 

I don't like those plastic hose clamps either.

I use these Made in Germany 100% Stainless Steel hose clamps.

Racetronix - Hose Clamp, Made in Germany 304SS

I forget which ones now but I got them in the correct sizes to do the rubber hoses typically found on GM cars and trucks. 3/8, 5/16, 1/4

The rubber isolator will be just fine installed on the bottom of the fuel pump.

 

Never ever use the supplied littler connecting fuel hose when you don't have a pulsator. These hoses fail often after a few days and turn to chewing gum. Throw it away as far as you can and use a QUALITY fuel hose instead. Drop the tank again for this 10 cent hose is a real PITA.
and I would also recommend to throw away both O-rings that seal the sending unit to the tank and buy the ACDELCO G10 off Rockauto. It has the tabs that hold it in place when you put on the clamp ring.

 

Definitely want the rubber under pump to bracket.
use better submersible efi hose and better clamps.

 

Thanks for the info. Do you need a Pulsator ? Or is it ok without ?

 

I've never used the pulsator on any I've replaced and never had any problems. I think the newer design fuel pumps don't require one. I also don't care much for the big rubber O-rings that come with the tanks, hangers, and fuel pumps. The ACDelco G10 is nice. Didn't find it on Rock Auto but they have them on Amazon for like 9 bucks and some change.

 

Ordered the AC Delco seal from Amazon and some submersible fuel line and stainless clamps.

 

The AC Delco rubber gasket with the tabs, do the tabs face down when installed on the gas tank ?
That's the way I installed it and looked right to me.

 

Also, the sending unit tabs did not line up with the grooves on the new fuel tank. One was slightly off. Had to remove one tab to get it to work. Fuel lines are more straight. The old ones were bent up higher at the point where they bend down to make the connection to the car.

 

As best as I can remember that is the way it goes in. I think that's the only way it could go in and make any sense.

You are dealing with aftermarket parts and I have no idea which aftermarket they are. Sometimes you just have to do whatever you have to do to make it work.

 

I know. Thanks. Would be GM parts if they still made them. I just don’t want to pull the tank again after getting it back together.

 

Yes.
