I recently built, with the help of a friend, a 2F-EFI for a 75 FJ-40. I've driven it about 5,000 miles and it runs very well. The fuel injection is supplied by an external Mallory 4060FI fuel pump mounted to the frame just forward of the rear axel, slightly above the fuel tank outlet. The pump lifts fuel from the tank about 2 or 3 inches and puts out the necessary 38 to 42 psi to the injectors. The stock fuel tank is mounted inside beneath the passenger's seat. The fuel pump's electric motor (brushes) failed after about 80 hours of operation but I expected it to last for about 2,000 hours. I've replaced the pump with a second Mallory 4060FI while on a trip but suspect that it will fail early too. I'm about to install a different external pump but would really rather have an internal tank pump. I'm considering modifying (shortening) an 1992 FJ 80 fuel pump so that it will fit into a stock (modified) FJ 40 tank.
Do external fuel injection pumps work well and last a long time? Has anyone modified a stock FJ 40 tank to receive an internal pump? Do you know of anyone in the SF Bay Area who is considered an expert in fuel tank modifications?
Thanks
Terry
