How is your gauge plumbed in to your fuel system? Meaning, is it all mechanical and you have an actual fuel line running to your dash gauge, or is there a pressure sensor there on the engine, either mechanical or electrical, etc. It can make a big difference because of the heat. For instance, my liquid filled pressure gauge, sitting about six inches away from the carb inlet, registers zero psi when the underhood temperature gets hot. Almost all do, unless they have a pressure release mechanism.
