Anyone know the easiest way to replace a fuel pump on a 86 z28

 

Well, that's going to be a matter of opinion I think. Maybe that's why nobody has responded yet. Some people wish to cut an opening from inside the car to "make it easier", but I don't think this is any less work than doing it right; so I'll describe the right way.

Drain the fuel tank. Then, you need to get the car up in the air, but supported by the body so that the rear end can swing down. Be sure to search for the safe places to support the car by its body. Support the rearend pumpkin with a floor jack. Disconnect shocks, disconnect the brake hose, and swing down the rear end by lowering the jack. You have to remove the rear part of the exhaust system (long pipe and muffler). Take off the heat shield AND PUT IT BACK ON WHEN YOU ARE REASSEMBLING IT. Now you can start working on getting the tank out so you can change the pump.

There should be plenty of writeups in the archive on the details of this. It sounds like allot of work, but it only take a few hours. Cutting the car will be just as much hassle since you will have to also hack up the fuel lines to get the pump out. Don't do that please.

 

OK lets cut a hole, no we will drop the tank, no cut a hole, drop the tank--LOL

 

I don't think you'll find me recommending a hole, ever. I just wanted to cover both methods and tout the best one.

 

Where would you cut a hole at if i did that ?

 

Ive seen them both done..

 

How hard is it to replace fuel injectors?

 

Hacking a hole into the car is no easier than doing it the correct way.

Get a tall set of jack stands, remove the exhaust rear section, remove the heat shields, remove the panhard bar, disconnect the rear brake hose where it connects to the rear end, lower the rear end as far as you can (having the car HIGH on stands counts here), disconnect the fuel lines, remove the plastic surround from the fuel filler, remove the strap bolts and take the straps out, then rotate the fuel tank down and out.

 

injectors are easy as cake

 

You trying to start a fight again?? Lol

 

So, are you replacing the injectors and the pump? Or just trying to figure out what's wrong.

 

i put a fuel pump n mine saturday morn in 4hrs by myself. i read all the stuff on here people was arguin bout cuttin a hole or droppin the tank. i pulled my carpet bak but couldnt bring myself 2 cut it. when i took the tank out and put it bak n i was glad i didnt cut nothin. its way easier than people make it sound. by the time u pull the carpet cut the lines and have 2 make somethin 2 cover the hole bak up and take the panels off 2 get the carpet bak n it takes longer than droppin the tank. jus drop the tank ull b happy u did,

 

Sure would've been nice if GM woulda made the fuel pump easier to replace. My old Chrysler LHS took 30 minutes to replace. Pull the carpet out of the trunk, remove three nuts, disconnect and remove the pump.
