Fuel Pump and Tanks ==== Fuel Pressure ==== Fuel pressure should be read before the adjustable regulator. The fuel pressure with the pumps running but engine off should be 4 to 5psi. When started, it is standard for the pressure of the tank to fall to 1psi (but should read less than 3.5psi.) ==== Rust Damaged Fuel Tanks ==== A fellow "G" owner has recommended using Moyer Fuel Tank Renu (in PA, USA) to repair damaged fuel tanks. ==== Removal and Replacement of Fuel Tanks ==== It is also rumored that in order to remove the driver side tank (US)/ passenger side tank (UK) you might need to actually pull the motor.
