Hello, my name is***** will assist you toady.

Have you already looked at the fuel in the VST for water?

Do you have a gauge to test the fuel pressure? It would need to read up to at least 100 PSI

There did not appear to be any water in the in line water separater but what is the vst?
Expert:  Charles replied 2 years ago.

The VST is the Vapor separator tank on the engine. It is where the fuel pumps are.

Have you done a compression test?
