Does anyone know or have a drawing of where what lines go where? My truck was originally a two tank truck but someone had removed everything. I'm installing the second take and putting in a new selector valve but I have no idea what lines go where???? On one side i have a small and large inlet/outlet and on the other side I have two small and two large inlets/outlets???

On one side i have a small and large inlet/outlet
These route to the front of the truck - the 3/8" is fuel supply to the pump and the 1/4" is fuel return to the tank. Both lines connect to the engine mounted fuel pump if carbureted - or route to the throttle body if TBI.
...and on the other side I have two small and two large inlets/outlets???
The right pair routes to the right tank, the left pair to the left tank.

Well, this and similar questions come up so often I was focused on gas rigs... but you're correct. It doesn't matter.
