Question: I have an ’87 Wrangler that now has a Chevy 350 motor. I’m having a problem with my fuel system, meaning I can only use 5 gal. of a 15 gal. tank. After dropping the fuel tank I found that the stock electric fuel pump is still installed and the 350 has a mechanical pump as well. My question is that if I bypass the electric fuel pump would that allow me to use my entire tank or do I need to completely remove it and the wiring? Frank B.
Answer: I know the 87 YJ used a carbureted 258 and an EFI 2.5L 4cyl so I will assume that the Jeep originally had a 4cyl. The 2 Jeeps used different type tanks. It would probably be easiest to get a tank from a (87-90) 6 cyl YJ. New ones are available from OK Auto or Quadratec too.
