Going to be getting a fuel pressure gauge and need to know where to get the feedback signal from. I have a Stewart Warner boost gauge now and probably will be going with their fuel gauge to keep the look the same, would they tell you where to get the signal?
Would this gauge work for our trucks?

Couple of pics of the boost and fuel gauges.

 

Try the Shrader valve on the crossover pipe between the fuel rails.Connect a sending unit to the Shrader valve and run your wires to the sending unit.You have to buy a separate sending unit.

 

Would that be for a mechanical only type gauge?
