Leaking fuel & truck won't start

[driverno8]

My buddy just called me stuck in L. A. Says his truck is pouring fuel out from the back of the engine compartment somewhere. Fuel everywhere. Truck won't start. I need some thoughts & solutions. He can't find the problem because everything is covered in fuel. Everytime he cranks it fuel pours out from somewhere. He's got a '04 600 with a Edge Juice. He had an EZ stacked on it for awhile but when the truck started acting up he took off the EZ. I'm thinking he blew a line. But here's some questions. Did he do the damage because of the EZ and raising pressure? Does the Juice raise pressure? Is this a quick fix or a dealer fix? And what is it that's leaking/where does he look? I've done some searches for fuel leaks and can't find any direct answers. Thanks a bunch guys!

Back of the engine might be the fuel line from the tank to the filter. He can try bumping the starter, but not starting the engine. If it is the fuel line before the injector pump, the lift pump will be pumping fuel on the ground without the engine running.



Also, check to make sure the water drain valve on the fuel filter is closed. That can cause the fuel to pump out (in large volume) of the fuel filter with the lift pump supplying it.



If there is no loss with just the lift pump running, then it will be either an injector line or the fuel return line to the tank. Either will show up only with the engine running and fuel being pressurized by the injector pump.

#6 line has a small split in it. He pulled the Juice out and it's getting towed to the dealer. What causes it? To much rail pressure? Does the Juice raise it or was it the EZ stack that did it?

I saw one other truck, an early 03 split the #6 line. Back then there were not any boxes available. That being said, the raised pressure is certainly harder on all fuel system parts than stock.
