Q: fuel pressure leak?

asked by on April 29, 2016

boy do I have a headache of a problem.I have a 1993 jeep grand Cherokee.Runs great but developed a fuel leak in back by fuel pump.Replaced the lines.Starts and runs fine for about two minutes then pressure seems to build and fuel pours out over the top of the fuel tank.Its very difficult to pinpoint exactly where it comes from,but it seems like some kind of back pressure is causing it to leak somewhere above the tank.Any hints?Thanks so much ahead of time.You help us all out so much.Been reading the posts,and just joined the community.
