2nd Gen Non-Engine/Transmission leaky fuel cap

[telliott]

my fuel cap is leaking fuel. i have fuel running down the side of my pickup below the fuel door. I know its not from over filling because i had 3/4 tank, washed my pickup, and the next day i still had a fuel spot. This started with the installation of the glacier system, so i assume the return pressure is great enough to cause a little leak. Is there a solution? can i get a fuel cap that seals better? i think it could probably be fixed by relocating the return line further down the filler neck, but i dont really feel like messing with that if i dont have to.
