Please list the Make/Model of the Pressure Gauge, or even a picture of its Face.

Please also clarify it's the 1989 carbed chassis you're working on. You ask for a wiring diagram 199-FIVE Bounder. Did you mean 1990? For that, I'd try a separate thread in Class A.

Also, what's the chassis model designation? I wanted to look at fuel pump etc. on RockAuto and found P20, P30, P40. Hadn't heard of P40, looked at P30 with 454.

One in-tank pump, only? The RockAuto page shows mechanical engine-mounted pumps.

I'm told the 454 needs 25-GPH on a full power climb.
