I have a new to me '92 Chevy van c-30 that is strictly propane. It was converted in '92. It has two tanks one of which works fine. The other is full but it won't feed the motor any fuel. From underneath, on each tank, there is a fuel fill line, two wires leading to gauge sending unit?, fuel feed line leading to a t fitting. The t has a blue plastic cap that when pulled reveals what looks like an oversize Schrader (relief?) valve. My research indicates this is a "t-connection integral relief valve,twin tank double back check".
Is there a simple fix, or, what should I be checking? I will post more info as needed.
Thanks, Richard

I had a forklift I had to tap the regulator with a hammer sometimes to get it to allow fuel to pass...
