Does anyone know where i can get the wiring diagram for the fuel pump and can anyone help me find the right way the gas line goes to the carburator? just put another motor in it but can not figure why thw electric fuel pump is not kicking in. thank you

Are you sure you have a carburator? The only vehicle in 88 that was carburated was the ram 50. It is supposed to have a throttle body.

it has a throttle body. is there a certain way the fuel line goes?

The big line is from the pump and it goes on the big line at the throttle body. The small line is the returnline. It goes on the small line connector. Good luck
