Hi guys,
I have a manual override switch on my fuel pump. It is a push button. When I haven't run the engine in a long time, I hold the push button down to activate the pump. This eliminates the need to crank the engine to raise the oil pressure to active the pressure switch to turn the pump on. I thought the push button was a pretty slick idea. The switch is located near the pump so I can listen for a change in the pump noise after it fills the carburetor bowl and carburetor needle valve closes.
But I have run into a snag. For some reason, my pump now sounds the same regardless of fuel flow. Or maybe sometimes the bowl is already filled when I push the button so I don't hear the change in pump noise that I expect.
The last time I tried to start the engine, I had trouble. The engine wouldn't start. Part of the troubleshooting drill is to check for fuel. I wasn't sure the pump was working, so I pulled the fuel line off the carburetor end. This is messy, smelly, and a little bit dangerous. I always get gas on my hands.
So, I was thinking of adding a fuel pressure gauge between the pump and the carburetor to detect when the bowl needle valve closes. Has anyone blazed this trail ahead of me? Is there a way to check for fuel delivery without getting their hands wet with gasoline?
