Hello,
The vehicle: 1988 F-350 with 7.5 (460) fuel injected engine.
The problem: The truck runs fine on rear tank but starves for fuel when the forward tank is selected. The gauge reads full on both settings (both tanks are full at this time). I expect I have a faulty low pressure pump in the forward tank but I keep wondering if the mechanical selector could be at fault; is it possible it's not fully switching to the forward tank yet still connecting to the forward tank sending unit? Are there other possibilities I'm overlooking? Any advice is appreciated.
Thank you. Carl
