Ruptured High Pressure Fuel Line

[DWBauer]

I just had to take my truck in and get a high pressure line to injector number five replaced because it ruptured. It was spraying fuel all over the inside of the engine compartment and I went through several gallons of fuel before getting it to the dealer. I haven't chip the engine or modified anything other than intake and exhaust. I was wondering whether this is a common problem or did I just get a fluke fuel line?

I had to help a co-worker replace a hp line on his '05, he wasn't even able to start the truck. His was leaking at the crimped on end. He was lucky, mine was down with the injectors out so we stole one of my lines to get him going again because it was going to be a week before the replacement line came in.

I'd say it's probably a fluke. I haven't noticed very many injector line failures around here.

truck is a 04. 5 stock

I hope it's a fluke because I'd hate to have that happen when I'm out in the middle of the Nevada desert. I took a chance and drove it to the dealer even though it was leaking so badly, but it wouldn't have made it much farther the way it was spraying fuel. Luck was on my side that it broke in town.

hmm. . might be worth getting a rail fitting test cap. . get a broke line, pull it off and cap the rail. run home on 5 cylinders...

I had #5 line crack at 135000mi. The clamp was loose, I should have checked and fixed the problem before it broke.

 

[DWBauer]

That's a good idea! I didn't think about the clamps but that certainly might accerate a weakness because of vibration. I'll have to check that every once in a while.

I've wrote on this before and got no reply. I've had a leaking #5 for quite some time. It's been replaced twice and still leaks. And now its getting hard to start in the mornings. I'm still trying to pin point where the leak is coming from, the #5 fitting or the #4 fitting. Has the Dealer repair worked. For a long time I thought it was just oil coming out of the crankcase vent but its fuel running down the outside of the vent tube.

 

[DWBauer]

So far the dealer repair has been doing fine. They replaced the one fuel tube and both fittings on it. No leaks so far but I've only run it a hundred miles or so since the repair.

Who did the work?

Most of the broken lines are going to be loose line clamps. The vibration will fatigue things in a hurry. The common rail lines are made of thicker material than the 02 and earlier, and the 6. 7 tubes are larger yet to withstand the higher pressures.

That makes sense, but then why doesn't the #1 line break more often? My #1 line has no clamp on it at all.

 

[Scrappy]

the one I replaced was due to the clamp.

I had Integrity Dodge here in Las Vegas do the work for me. I wasn't interested in sticking my face into the engine compartment with a high pressure leak there. I've seen what high pressure hydralic fluid will do to your body parts and it's not pretty.

Mine ruptured line #4 on the way out to a camping trip in the middle of NV. Exactly the same, sprayed fuel, engine compartment, undercarriage soaked, etc...

I have replaced a bunch of #5 fuel lines on the small transit buses at work with the 5. 9 CR engine.

My dealer was as replacing the #4 on another truck when I had my blend door fixed. Says it is very common for #4 and #5. I'll be looking of it.

Got truck back sat it was #4 asked if clamp was lose they said no
