Fuel related question

My truck was originally gas and there was no switching valve on the rail like on a diesel but I've read other swaps and they said the diesel one bolted inplace of the gas one? How is this possible? It's got what looks like a little block then a split for the front tank and it continues to the rear thank that doesn't sound like the return would work correctly any one able to she'd any light on this? It worked fine when it was running. I wanted to reuse the lines cause the others were trashed and if I flushed them out they would be fine but this is a whole new problem.

I know this but what I wanted to know was how they are switched in the gas trucks because there is no switching valve and they do it through the pumps themselves not through a splitting valve like the diesels do

On gas trucks, when you switch tanks, you are putting power from one pump to the other and it will only return gas to the tank it's pumping from. I think there are check valves in the return lines that are controlled by the pressure from the pump.

Yea they are in the pumps so that means custom lines here I come. Does anyone have a diagram for the valve in the diesel trucks like a tard I forgot to take a pic or make a diagram of how the lines are hooked up
