Bypassing mechanical pump
Instructions for fass system say "injector return line" must "T" into p7100 return line.. Injector return line goes across 6 injectors and back to stock fuel filter unit. Is this the line I am supposed to cut and T??? Instructions dont give much detail or pics at this point.. I would guess the instructions should say to "T" the "p7100 fuel inlet hose" to p7100 return line....or am I wrong?? I assume that is the only way to run it being that the mechanical pump has to run and needs fuel flowing through it all the time. Am I missing anything or assuming wrong??
