How do you change electric fuel pump in a 1997 Z28 camaro?

Answer 1

Inside the fuel tank. Unless there is an access panel in the trunk or under the rear seat, the tank must be removed. I had the same problem in a 95 Z (you need 35 psi if not your car will spit and spuder and be very hard to start especially after the engine has heated up and been turned off the try to restart and it will act like it is out of gas) and rather then spending several hundred dollars at a shop or hours removing muffler, stablizer bar and gas tank. I cut a three sided rectangluar hole about in the middle of the hump that is between the back trunk area and the back seat. You need to be EXTREMELY careful not to drill or cut into the tank (there is less then a inch between the sheet metal your cutting and your tank and lines) or any of the gaslines running up to the engine. Of course don't use a torch, I used an small air saw. You can crawl under the car and see where the gas lines go up to the tank (you'll have to look around the muffler) or get a picture of the gas tank (I went and looked at a tank in a junk yard and made a couple of measurements)the pump is mounted into the tank top with 4 or 5 small bolts and is just about centered left to right and front to back on that hump. I believe I cut about a 8" x 12" area, I only cut three side leaving the panel attached for easier re-sealing. Make the 12" cut in the front to back direction as the tubes running from the pump run towards the front of the gas tank and car and extend from the center of the pump 6 or 8 inches. After I replaced the pump I left everything opened and took it for a test drive to make sure there were no problems. After that I cut a larger piece of tin to cover the enter hole with about 1 inch extra all around and drilled holes and ran a wide silcone bead around the edge and pop rivited it down,throw back the carpet and your good to go. This only took about 1 1/2 hour to do the entire job including test drive. Hope this is helpful. *I had the same problem on my 95 Z28. Cutting the rear deck works really well. It's a tight fit though getting everything out if you don't disconnect the lines on the outside of the top of the tank. Also the replacement pump had a different high pressure output line than the manufacturer, do this connection had to be done inside the tank with not a lot of room for fat fingers(Good Times!!). Also the mountong bracket for the pump & level sending unit is hinged so disconnect your electrical connector first.
