I added an electric fuel pump as a priming pump. the one I install is suppose to work as a stand alone pump or can be used as a priming pump. I wired it with a spring loaded push button so in only runs when I manually push the button. the reason for the pump is that after my truck sits for a while the fuel drains out of the line and it take a lot of cranking until the fuel line is charged again. After that, the truck runs fine and will start right up until it has sit for a couple days.
Here is the issue. I have the pump installed about 2 feet from the gas tank. This particular pump works better pushing fuel so it was suggested to have it close to the tank. I push the button and can hear the pump going the town. Problem is, I don't see any fuel being pushed into the clear fuel filter that sits right in front of my carburetor. I still have to manually prime the carburetor with a squirt of gas from a bottle. I wouldn't think so but if I have it wired backwards could it be running in reverse and trying to push gas toward the gas tank? I know my heater fan motor reverses direction when I reverse the polarity. I can easily reverse the wiring to test it but I was not sure if that would possibly damage the pump if I wired it with the polarity reversed.
