I just bought a 1985 Nissan pickup and I'm having some problems. It will idle fine and run ok until i head uphill. I was told to replace the fuel pump and i did. Now it leaks gas from around the accelerator pump when it's running. Not Constantly, but enough to worry me. I live in the middle of nowhere and have no one to help out with this. I will have to fix this on my own. any Advice?
