Ok so I have a 1990 r3500 western hauler. It had a fuel tank in the bed that was cracked. I took the fuel tank out and plugged the lines and now it won't start. If you pour fuel in the throttle body it will fire. So can anybody help me

Yeah actually there are lines that run to the original tank selector valve. And the pump wires are extended up to it.
