Fuel not even leaving tank! Reaching desparation. . . 120-130 66

posted by  someone claiming to be Justin on  Fri Nov 24 17:26 CST 2000 [RELATED]

Hello,

I have a '66 122 that I am installing D-jet fuel injection into. I was all ready to get it started yesterday when I discovered that when I crank the engine, fuel is not even leaving the tank of the car.

Because the 122 was not built with a high pressure fuel injection system in mind, the tank does not have a fuel return location anywhere. What I did instead was to installed a brass 'T' in the line, before the fuel pump. That way, returning fuel would not be under pressure, and it could drain back into the tank or go to the pump. Does this make sense?

What I think is happening now is that the suction from the pump is pulling air from the return line and not fuel from the tank. The 'T' does not have any way of regulating direction of flow.

So, this is where the question comes; Is there a one-way valve sort of thing that I could install in the return path to allow fuel into the tank, but prevent the pump from pulling in air instead of gas? This seems like the easiest solution at the moment. I could also remove the tank and get a fitting installed to attach the return line to, thus separating the fuel pickup and return.

What other ideas do people have? I am surely overlooking a simpler solution. I am at a loss at the moment, really. I dearly want to get this car started.

Thanks
