Last summer I was stuck on a higway with a fuel line that busted at the pump, 500 miles from home. Fuel was alllll over the place. I managed to get to a garage but it was friday, the guy could not get a new line before a couple of days, after monday....He finnaly found one at a junk yard, lucky I could continue my summer trip.

I have all kind of spare hose in the truck but never thaught I could not fix this one. This is a very high pressure line.

I wonder if I could have a flexible line made up so I could replace a line if I have to? I often go in the bush, far from home. Or do you know a fix for these line that could work?

 

Are we talking a line fron the IP to the injectors?
Or a line from the lift pump to the IP by way of the filter?

 

I do not know to much on what you are talking about but about 8 months ago I thought someone was siphoning from my rear tank. Later I found that it was really just a fuel leak that was getting worse. I made a tempory fix that still works today. I took some chemical resistand hose and cut a sections that could cover the crack and extend about an inch past on each side. I cut the hose down the side to so it would slide over the cracked hose. Then I used a series of ring clamps to hold it all in place and like I said it holds together still even with some off-roading. When I can afford it I will replace the whole system so I may eventually move to bio. Oh, does anyone know the approimate cost of replacing all of the rubber on the fuel system. It is an 1988 F-250 XLT Lariet with the 7.3, thanks.

 

If it was a "very high pressure" fuel line then you must be talking about one of the injector lines. These lines are very thick (very small hole inside) to withstand the pressure and they are of a very specific length (which is why they are so oddly shaped). You can't just put in a generic line. If one of your lines broke it may have been because the line wasn't properly clamped down somewhere. There are numerous little clamps that hold the lines together and if they become loose or come off then these lines will fatigue and break. Here is a photo of the retaining clamps. Make sure they are in place and tight. Another reason it could have broke is someone timed the pump without loosening the injector lines at the pump and caused undue strain on the fuel lines.

You can't just put in a flexible line or a generic line if you develop another crack or break or pinhole (BTW...never put your hand near fuel spraying out of these lines while the engine is running...the fuel pressure can penetrate your skin and can die from blood poisoning). But you can get some thick (marine A-1) fuel line (probably 5/16") and place it over the leak and clamp it down with some #2 hose clamps and that should be enough to minimize the leak until you get to a shop for a proper repair. Or you can carry spare injecor lines...but you will need 8 of them because I beleive each is different but that's not a cheap choice.

 

There is no easy way to fix the high pressure lines other than carry each of the eight pre-fabricated lines so you could replace them in kind. These lines have special fittings and each is made to a special length.
