Fuel everywhere under the hood!!!

[snowracer69]

My former roommates '03 250HP CTD had issues two nights ago. He called me and said he'd just pulled a hard hill (8% grade for 2 miles) and topped out at about 95 MPH on it and held it there. He has no gages, but has an EZ on it w/ jumpers set on the highest (70 I think?) setting.



Story goes that when he got to the top of the hill, went into a resteraunt parking lot, let her cool down for about 3 minutes and then shut her down and got out, there was fuel EVERYWHERE under the drivers side of the engine!!! He opened the hood and said EVERYTHING was soaked w/ diesel! He looked for it, but couldn't tell where it was coming from. So, with a friend watching, he started her back up and there was no leak. He's drove it the last 2 days and hasn't seen another drop of diesel. He said there was no doubt it was diesel, fresh, and from somewhere under his hood!



Where could it have come from, and what could cause this? The only thing I can come up with is maybe the fuel filter drain opened itself up and was pumping fuel out (he said the hose doesn't clear the engine compartment, and at 90 MPH I'd assume that the fuel would blow back up into it) and then when he shut down it closed again and has remained that way since.



Any help appreciated. I'm 950 miles from the pickup right now, so not a lot I can do for him.

He did that with no gauges He's lucky that's all that happened.

My 04. 5 had an injector pump seal leaking and did the same thing. Diesel everywhere, especially on the drivers side. I laid under it in a parking lot with the engine idling for about 15 minutes and couldn't find any leak. This really puzzled me because there was diesel everywhere. Dealership also had a hard time finding the leak because it wouldn't leak until you built pump pressure. At low rpm nothing but at sustained highway speed it would start to leak and the faster you went the more it leaked. Don't know if that's his problem but it sounds similar. By the way, the truck ran fine the whole time it was leaking - - just getting fuel everywhere.

I may have read something early in the EZ discussions about a leak that developed when it was used on the highest settings. Very vauge memories but you amy find it with a search.

I understand they upgraded the seals (washers) on the rail mid year on the '03s. If he has the older style they could leak with the increased pressure of the EZ.

This happened to mine and it was the 6th injector line nut (at the rail) I was running it hard with the box set high.

Good job Keith!

My #6 injector tube actually cracked and did the same thing.
