Hello,
I'm gonna take the plunge for a new tank, pump and hard lines.
I use the stock '89 fuel pump with a regulator to a 4 barrel, so it seems kind of silly of me to buy another 40lb fuel pump since my regulator's seen better days too.
I can't find anything that plainly says it's compatible with this year tank design so I'm hesitant.
Sooo if anyone knows of one they know works I'd be grateful. I was also thinking a pump labeled for a 1986 car might work if someone knows if all the tanks are the same.
This is the tank I was planning to order:

Thanks

 

The 1989 TBI fuel pump is 12lbs, the TPI is 40lbs.

You could also buy a 82 tank and pump for a carb car. https://www.rockauto.com/en/moreinfo...50974&jsn=1062

 

Hey thanks for the reply,
you said TBI twice but I know what you're after. This is a TPI fuel pump around 40 pounds I think.
I was looking at the compatibility list for that tank I linked and it says 82-92 so I guess all third gen tanks must be about the same.
I'm kind of surprised they made in-tank pumps in 1982. I have an '83 Chevy van with a mechanical pump

 

Updated comment to avoid someone seeing the wrong info.

 

Physically a tank from 82-2002 will fit in your car, the 4th gen tank changes to plastic in the latter runs. Fuel pump's don't interchange between 3ed and 4th gen tanks, and 4th gen tanks have the wrong fuel gauge sender range. I have a 2000 firebird tank in my car using a grand prix fuel sender which mostly fits the pump housing and is the right ohm range.

I think the carb cars in 82 had extenral pumps they probably just had a strainer and sender in the tank, at least if you look at the parts cat 82 carb car they list an engine driven pump. Personally for a carb conversion I would do that, just run the strainer in the tank and put a mechanical or electric pump outside the tank...

 

That's good info thanks.

I like that idea, an external electric pump. It won't be such a pain in the behind to replace if I ever need to.
So I'll get an universal pump then.
I've been doing some online shopping for a new simple sending unit+strainer combo without the pump and return line that would be on a '82-83 car without much luck though.
I'd like to put in all new shiny parts if I'm going through all the trouble of dropping the axle and tank y'know.
Everything that looks like what I want fits a '70ish tank and everything listed for our generation is a 4 line in-tank pump job.
I'll keep looking though thanks for your help.

 

If you are using a carb, (and needing a new regulator) why not just go with a block mounted mechanical? I put a new tank on my 83 (ccc quadrajet) and a new mech pump and it's been solid. You will almost guarantee have to modify any 'new' sending unit if you aren't using an in tank pump, unless your existing sender is fine. Mine was rusted to hell so I had to buy a new one and extend the pickup tube (and the gauge is about 1/4 tank off... my fault for not checking before putting the rear end back in though).

 

Hiya.
I could, I don't have much experience with mechanical pumps though to be honest.
Although different, only time I messed with them is when I took apart and cleaned a high pressure pump for a Detroit diesel for a friend and it was like clockwork inside. I struggled putting it back together and said never again.
The price for a brand name electric pump is pretty low compared to the old days also, they're almost disposable.
I'm sure it works I just kinda wanna go with what I'm comfortable working with.

For the sender, mine does work okay but what kind of modifications do you mean?
The problem with my sender unit is the hard line coming out of the top is rotted out. I have some steel braided hose and hose clamps covering up leaks as far up as I could get the hose to the bend where it goes to the top of the tank, which is not ideal @ 40 psi to say the least. I have a bypass regulator and both lines have leaks too unfortunately. The hardline just before the fuel filter gave out a few years ago also, so I made that one big long piece from the top of the tank to the fuel filter
My tank is rotted out from the inside and I keep getting pinhole leaks I'm tired of JBwelding is the source for this project, I don't know if I mentioned that.
Time's a bitch huh

 

It's all but impossible to find a carb pickup/sender. The FI ones aren't deep enough without the in-tank pump and strainer/sock. If you don't have an in-tank pump, you need to extend the pickup. My tank looked like it was full of chocolate milk so I know the rotting from the inside out. I got a new after-market tank, and a FI sender (expecting an in-tank pump). Added some additional steel line and it works great for me with a stock quadrajet and mechanical pump.

Mechanical pumps are pretty simple if you have a carb especially a stock one. Most are the right pressure already. Just bolt on and go. This is if you have the cam lobe and pushrod (as well as a block that has the provisions for a mechanical pump).

The easiest (least modifications) would be to get a new tank, new FI sender, in-tank pump, and regulator. (and.. as I re-read, maybe new hard line all the way??) More parts, but little if any need to modify anything against it's will.

Kinda depends what you feel most comfortable with, and safe with given that messing with fuel isn't to be taken too lightly.

In the pics the old sender is on the right, new on the left. The one without the sock I cut off the pump mount, and the one with, I added in the extra eh.. 4-5 inches of steel tubing and the sock/strainer.

 

Radiator shop can take the pump assembly and cap off the return and braze on any combination of lines and fittings.

 

Thanks guys.
I'm about 1/2 way through the job now. I got a 5-9psi external electric pump and I'm going to clean up and modify the stock sender, extend the pickup like in Dev's picture.
New tank too, came with half a dozen dents though kinda annoying.
Boy I busted my *** trying to get the panhard bar and track arm out of there.
Managed to do it with a lot of cursing and a little fire damage though

 

I ended up having to cut the bolt off of the panhard when I dropped my tank. Sawzall between the two parts made short work of it, easy enough to get a new bolt and bushing.

Only thing to know before getting it all put back together, is try and match the float level of the original unit. I didn't with mine and it reads about 1/4th tank low. (So full is 3/4 for me, etc.)

Also, not shown in my pics, I had to use the pigtail from the original sender as well. The new one expecting the in-tank pump had 3 or 4 leads, while my stock one had 2 I believe. Easy enough to figure out, one was ground one was to the float.

Just a few things you might run into.

 

Cool. I have the newer assembly for fuel injection, the float and sending unit hang off the return line so I don't have to mess with them. I'm just going to cap off the return since I'm not using the bypass regulator anymore and let it be the hangar for the float.
My strainer is different than yours, it's shaped more like a regular human sock with a brass ring that was press fit over a nylon nipple on the pump. I don't see any good way to attach it to the hard line I was planning to extend the pickup with. I think I'm going to grind an angle on the hard line and forget the sock. I'll have to find a new place to store my coins and bottle caps though

 

Yeah, mine was an FI sender. What I mean by the float/sender is hold your old one and the new one up. see that the floats rest at the same place. Apparently mine did not. And yes, I bought a separate strainer that had the right diameter hole to fit the supply line. If you have an inline filter before the pump outside of the tank you may not need the sock, otherwise I'd try to get one on that line. It'll save a lot of crap from getting into the pump and beyond.
