how hard to replace fuel pump?

[wiserocz]

Cutting the steel lines really isn't a big deal. The metal in the back around the fuel pump is really thin and can be cut with a ordinary tin snip. If you are nice and neat you can bend the metal back and make yourself a nice door. We actually used a computer case door for our fuel trap door. Looked real nice and neat. Ordinarily though you have carpet over it. Also I've heard of folks with used Camaros going through all the trouble of dropping their tank to remove the fuel pump. Only to find that the previous owner had already made a door, so be sure to check first. Without pulling the carpet you'll have no idea if there's already been a door installed.

BTW here is the placement on a 4th gen.

Yes we had to cut the hard lines.

There's fuel out, fuel return, and a couple of breathers. I little work with some fuel injection hose and you are back up and running. The biggest issue with dropping the tank is if the fuel pump dies again or you get a bad one out of the gate.

I've heard a bunch of grumbling that its hacking your car up. It appears no different from the outside, doesn't remove any rigidity, and corrects a flaw in serviceability of the vehicle. People say dropping the tank is the "right way". I would assume they think that because its more of a mod and not in a service manual.

Yep, and that was the point...without cutting the steel fuel lines you would have to cut an enormous hole in the trunk of a 3rd gen to do the trap door method.

Looks like you cut the hard lines coming off the pump.

Thats what I thinking as well.

We did the trap door method on a 3rd gen IROC and are super glad we did.

Here's some pics...

As you can see if we had carpet, no one would notice. Its all good until you get it back together and she doesn't fire or the fuel pump dies. Then you LOVE the door.

Thus the lemon ride. Strangely after replacing a drivers side door, the drivers side fender, and a WHOLE LOTTA patching and bondo it looked pretty nice once done.

The trap door method is not a good Idea on a 3rd gen. The hole would need to be about 18-24" x about 3 feet to get the sender and fuel lines out. .

YIKES! That's huge! Definitely agree with Gary then. On a 4th gen it's a pretty small hole and is the best way to do it but man that's a huge hole for the 3rd gens.

[esoteric18]

imo you should always drop the tank unless a previous owner already made a trap door

It took me about 2-1/2 hour to change the pump in my Iroc and I droped the tank. Alot of people say you need to drop the rear to do it but that is a false startment. You need to remove the exhuast, Heat shield, panhard bar and the rigd support bar above it, and the pass side shock and spring. I not really the hard of a job.

I learned something today

I agree with Gary droping the tank is not hard at all, I recently dropped the tank outta my RS to replace it and like Gary said the rear does not have to come out to do so. I had to wiggle mine a little bit but it did drop out...

Ah - that might be quite a difference then. The hole on the 4th gen isn't that hole (atleast in my opinion)

[WMCCjames]

Not sure on 4th gens but on 3rd gens if you choose to do the trap door, you have to cut a really large hole because the fuel lines on the top of the tank are steel and run all the way over and down off to the side of the tank.
