Yes, a fuel tank vent can be installed backwards, but doing so can lead to improper functioning. If installed incorrectly, it may not allow air to enter the tank as fuel is drawn out, potentially creating a vacuum that restricts fuel flow. This can result in poor engine performance or stalling. Always refer to the manufacturer's specifications to ensure correct installation.

you are going to have to drop the tank.... place a jack under the gas tank to support it while removing the two tank straps, once removed lower the fuel tank and remove the fill & vent hose's, fuel lines, and electric harness. now just remove the sending unit from the tank. now all you have to do is take out the old fuel pump and replace it then put it all back together shouldn't take more than a few hours...
