I dropped my tank to clean it about a month ago... I noticed that it smells a little like fuel and when I take the cap off the tank it hisses like the tank is pressurized! The other day, the damn thing sputtered, cut off and now won't restart! It's a 1987 YJ with 20 gal plastic tank, Weber 32/36, nuttered 6 cyl.
Why would there be pressure in the tank? I redid all of my lines except the metal ones when I dropped the tank. I need help!
So I dropped my tank again, and the vent was pinched. I cut out the pinched section and re-installed the tank. Now the thing will start, but will only run for about a minute and then cut off. If it sits for a few minutes and I pump the gas pedal, it will start again and run for a minute and cut off. What the heck is going on?? Any ideas?
Now you may have pinched a fuel line. Take the fuel line off the carb side of the fuel pump hold it in a container and have some one crank the motor over a couple of times see if you have any gas comming out.
