Shifty was right. My fuel pressure was tested at 5 PSI. We are set to replace the fuel pump. We are going to give it a shot ourselves.

We have a service manual but we are not planning to remove the rearend.

This is what we have done so far:

1. The car is jacked up where the rear tires are 5 inches off the ground.

2. All fittings and fastners have been sprayed with a penetrating/rust removal spray.

3. The exhaust is being removed tomorrow.

Has anyone a step by step list of a home removal. We understand the book proceedure but since we do not have access to a lift, clearance is an issue. We have a good idea what to do but would appreciate any hints, do's and don'ts.

Thanks in advance. Randy

 

I've heard of folks cutting the area above fuel tank to get to the pump. I plan on doing this when my pump dies.

 

oh man please please please dont cut your car up to change the fuel pump its hidious .....and rediculous to do when all you have to do is ....
1. jack up the car and support it well and spray all the bolts down with rust inhibitor
2. remove the gas cap door and plastic bracket around the cap inside the door .
3. take off the wheels
4. remove the exhaust
5. disconnect the pump wiring obove the rearend ..you will see the plug when you get down there.
6. disconnect the lower control arms on the rearend and remove.
7. remove the gas lines where they connect to the tank
8. some people remove the shocks ..we didnt and had no problems but the shocks were worn out on the car we did it on last time..lol..
9. remove the straps holding the tank up
10. have a friend stand on the outside of the car and guide the filler neck into the hole while your under it pulling it out ..
11. replace tank and do everything in reverse..lol
when you get everything loosened up on the suspension you will want to reposition your stands so you can lower the rearend down as far as it will go

im sure ive forgotten a couple small things in there so if any one else can think of what ive forgotten please post it for blane41 so he doesnt cut up his ride to change a fuel pump ...

if you have a friend or two that dont mind getting dirty then you should have it done in a couple hours just remember to be nice and buy em a burger and fries when your done to show your appreciation...lol...

hope that helps

 

How did you test your fuel pump to see how much pressure you have? did you do it your self or did you have to take it somewhere?

 

In short, if I were you I would have paid someone for this crap job. I think this is quite possibly the biggest PIA job to do on this car, but that's just my opinion.

Good luck man.

 

Thanks for the entertainment!

Do it the right way and drop the tank, put a good Walboro pump in there and be done with it.

Someone edited my post.

 

Your right, cutting the top of the tank is too risky.

I'll be doing mines the right (and safer) way.

 

not that hard of a job if youve got a friend to come over and help ya its only a couple hour job and thats taking a break

 

Go to a GM dealer, ask for an LS1 pump. LIfetime warranty on parts and labor.

 

What will that cost? I've heard of dealers charging as much as $900 to replace with a stock pump.

 

900$ thats outragous according to the labor books i believe its only like little less than 4 hours and if you figure 70 dollars an hour for labor thats only 280 total for labor at most then the price of the pump cant be 620 dollars ....

 

Outragous yes.
I guess my point is get an estimate first as the price varies greatly.

 

I was qouted 408 and change for mine. Still havnt got it done yet.

 

damn maybe i need to start advertising that ill do it for 100 bucks plus the price of the pump just bring em over to my place have it done in a couple hours no problem....lol....could make some serious cash that way

 

WOW. Your just in time to come over and help me then, for free. I will say that removing three inch flowmaster exhaust is a job that I had to use a cutting torch on.

Good thing I am going to a different set up.

 

that sucks about the exhaust man what you gonna do with it? you said your going to a different set up what you going to now?
where exactly you located at in illinois? im in staunton illinois about 45 min south of springfield anywhere close to that ?

 

my friend was quoted 600 on the swap, i opted to just do the swap for him for free.....wasnt too hard....i have no clue how you people do it without dropping the rear down to the ground......i pulled mine and his tank....both 92 rs's.....was impossible to do without dropping the rear....... might have been possible but more of a PITA...easier to just drop the rear...only takes 30 more mins of work to make life a lot easier.......

and this being the PITA thing to do on a third gen...haha yea right....i have rebuilt ever damn thing on the car....i STILL rank the header swap being the #1 pita throw-a-tool job in the world. even the rear end rebuild/gear swap was easier than that.....maybe a lil more tedious though....gear swap had me pretty mad too come to think of it.....

in any event quit ya bitchen and pull the damn tank...its not that hard....wussy.

 

cant agree more its not that hard of a job and i get a kick outta some of these people that would rather cut a damn hole in there car rather than just do the job correct...

 

yeah, id say cutting the hole would be more of a pita.....having to be that careful and exact, id much rather just pull bolts out....

how big does the hole have to be to pull the damn bent metal lines out that way?? im imagining something the size of a flippin coffee table.....i dont see how thatd be easier....

people just need to do what im doing...rip the tank out....pull the pump out......put a external electric on it...call it a day......

 

When people cut the car to get it out, they cut the metal lines too and use rubber there. Thats not the big deal though, its just the fact that the person is so damn lazy they would rather cut a hole then do it right.

Tibo- you cut some flowmaster exhaust off? what kind of shape was it in?

 

ive had to cut exhausts off due to them being welded to those hanger brackets and when they pulled the cat off to straigh tpipe it.....welded it all the way down...only thing not welded was the y pipe at the manifolds.....sooooo...sawzalllllllllllllllllllllllllllllllllllllllllllllllllll at your dumbass *i need everything welded* expense lol...jk

 

I didn't take the control arms loose when I did mine. I did, however, unbolt the bottom ends of the rear shocks to allow the rear end to drop down to the ground (with the wheels off).

Also, the panhard bar and associated brace were left off of the list. Oh, and the heat shield over the muffler too. These three items are not to tough to tackle though. Except for the fact that no tools ever seem to be the right size for the panhard bar nuts and bolts

 

thanks i knew id forget somethings but im just trying to help out

oh yeah still like the avatar man ..LOL

 

Whenever I see your posts with those gears, I start off thinking "I don't remember writing that" and then realize it was you not me.

I hate to point out things left off (I'm never meanin' no harm), but figured I'd throw them in anyways.

 

do the job correct ? I correctly modified my car to be ablile to access the fuel pump in minutes. Just like you (hopefully) correctly modified your car for more power. ( 350 motor) Some people would say that you ruined your car because its not correct any more(stock) . I myself don't have any problem with you modifing your car to suit your preferences. Some people do a swap and its a horible hack job. I'm willing to give you the benefit of the doubt that you did a good job. Could I have the same consideration? Many new cars come with fuel pump access panels. Would you still drop the tank cause its the only right way? Not every one who cuts a hole to get at the fuel pump is a hack, or lazzy. I WILL AGREE that most people don't have the skills and equipment to do a good job at it, but I get sick of people acting real self rightous and judging every one elses work with out seeing it.

Enjoy your 84 with 350 motor

 

thank you i will enjoy my 84 with a 350 engine and i hope you enjoy your car with a hole in it ...lol...enough is enough with the stupid replies about comparing an engine swap to a hole being cut into a car to replace something so easy ....LMAO if the factory would have put an access panel into these cars they would have done it alot better than almost every one on here ive seen so far not saying that all of them are hack jobs just 99% of em are there are a few that bought a nice kit to do it with i just dont think its that hard of a job to do and it is just being lazy when its only a 2 hour job to do and dont start with the i can change mine next time alot quicker because if you do it right the first time and buy a good pump honestly how often are you gonna have to replace it ...lol...i replaced mine only once in 10 years so its not a necessity unless your running a race car and have to change it between rounds or something do you understand what im trying to say ? its not a usefull "mod" as some call it ...it is just being to LAZY to do it right and unbolt some stuff and rebolt it back up its not being smart or crafty ..lol..and yes alot of newer cars come with one built in from the factory but it is done correctly and is built right not a hack as most of them ive seen ......

 

........am i missing something here......did some of you get beat with the stupid stick......

why in the hell are all these people putting in tank pumps back in their cars........cutting holes in the rear of their car possibly messing up the structural integrity of the car........

EXTERNAL ELECTRIC PUMP.......

im assuming here, yes i AM assuming.....that this can be done......i mean......this is what i plan on doing next week......

maybe the tpi people cant run external electric due to it needing tons of pressure and external electric pumps dont create as much pressure? not sure.......im carbed.....i carbed my car for the simplicity of the matter....

also.....not all of us slap a 350 in our cars....i stuck with my 305 since its roller and managned to pull 300 hp out of a l03 engine

yeah it took a lot of work.....but you know how funny it is to swear you beat people with a 305

 

Whats so great about switching to an LS1 fuel pump? Wouldnt it be a little much for a TBI? Im sure you can find a pump with the same specs and save money. Besides $600 or $800 is not worth paying just so you can say you have an LS1 fuel pump.

 

who the sweet jesus said a ls1 pump??

i was refering to something like a holley blue....but like i said my car is carbed......plus im going to run nitrous so i kinda need the extra gph...

once again, i dont know if you can even run those holley (whatever after market pump) with tpi.....it might HAVE to be in tank to build more psi? not sure......

all i was saying was.....first time the in tank pump dies., replace it with an external electric then you never have to go in the tank again.......

 

Yes, I had to cut my flowmaster set up off. For one connection I was able to cut a vertical slit up the pipe and pivot it out. I had to use a cutting torch to get the pipe that goes over the axle off. The system wasn't even a year ole and had maybe 15,000 miles on it. It can be welded back together by a competant person though.
One would just have to get a pipe of slightly larger diameter and use it to slip over and join the two cut pipes in a single union. I was getting rid of it anyway. I got Hooker Super competition long tube ceramic coated headers and I am doing true dual exhaust minus cats.

I had to unbolt my panhard bar, track brace, shocks, and sway bar to get my tank out. Even then it took a little convincing to come out.

I live 20 min. south of Decatur Illinois and about 50-60 min from Springfield Illinois. There are a few other guys from these boards that live nearby that were with me helping. Be great to meet you sometime.

 

Something else I don't understand is exactly how bg is the hole you cut to take out the pump. The Pump is held on to the pick up. You have to twist it, turn it, pull it out at an angle and then say abricadabra to get it out, and then the lines come with it too. So, how big is this HOLE?

 

heh....they cut the fuel lines .......on top of the tank where they are straight....

 

Taking the easy way out isn't always the easy way out. It is seldom the best way, either.

Thats cool, I live in Litchfield. Nice to finally see someone else from the area, not including the general

 

yeah it is

 

There are several of us insufferable FIBs in here.

 

cut the hole.saves yo ulike 4 hours of work.plus the welding cost on the muffler

 

And you still have a hole to fix!

 

No was fixed after the pump was in.
