I have a 1981 with the original carb and PROM and ECM. When my car was falling flat on its face while trying to accelerate I had the carb rebuilt. That did the trick for me.

The fuel pump on the '82 is inside the fuel tank. All other Shark cars have the fuel pumps mounted on the engine.

You don't have to drop the fuel tank to replace the pump. it will come out top after the fuel filler lid, hinge, and overflow apron is removed. It will require a fair amount of twisting and turning to get it out but IT WILL COME OUT. For that reason I suggest covering the surrounding area with tape or towels to prevent scratching paint. Once you hit the sweet spot where the pump comes out, make a note of how it was turned, you will have to turn it the same way to get it back in. Before you start removing hoses from the metal tubes at the back, mark then so you will get them back on the proper place.
Hi,
This is the fuel pump assy just before installation. I up graded the pump to a higher pressure/volume pump. So, this is slightly different from original. The 85 AC Delco pump is available and came with the connector pigtail for installation. I also rebuilt the TBIs around the same time. You can see why the assy needs to be rotated. I think it was counter clockwise to get to the sweet part. The hardest part was getting the hoses off the filler neck. I think loosening the hoses before removing the last few bolts holding the assy on the tank was the trick.
You may find the sock and hose falling apart when you remove the old one. I also replaced the frame mounted fuel filter while I was at it. The filter is located on the passenger side frame. I seem to remember it was just forward of the door. Easy to get to if you have it up on jack stands or on a lift.
