Replace fuel lines with aluminium?

I have a leak in my lines somewhere as I can smell the fuel (raw fuel) when I am driving and even when it is sitting in the drive way. With all the snow and wet roads right now it is impossible to find where it is leaking. I found rolls of alminium fuel line at summit and wonder if it will work with diesel fuel? If so I think I will buy some and run all new lines on the beast, They are kinda a mismatched set up right now. I will run all new supply and return lines and try to clean lings up some.

As long as the aluminum line is properly mounted securely and NOT rubbing on anything it would be fine. With the harmonics and vibrations of a diesel if anything was rubbing on the line it would wear a hole in it quick.

I'd suggest start by looking closely at the injector return lines. They are a more of a common spot to leak raw fuel where you would smell it in the cab.

I checked those today and they were all dry. I did have a problem with people moving them and had to replace the orings once. I don't let anyone touch stuff anymore lol. The body on this thing is in ruff shape right now so there are places air can get in I plan to do the body in the next couple years.

Kenobuck if you get a chance stop by a truck or trailer parts house and look at the nylon air lines. It is used on reefers for fuel line and might even be the same thing as our fuel line. It is extremely hard to wear out and would last forever. You buy it by the foot and it is around 50 cents.

I'm with Starmilt, Aluminum does not do vibration well. The nylon air lines are the smae material as the fuel lines. You could even try to heat the end in hot oil to push it onto the original fittings so you don't have a problem with fittings.

You don't need stratoflex it is too heavy and bulky plus expensive.

Nope I have done it a lot. Wheb I started running alaska the first trip I didn't even have a jacket, after that I started carrying all sizes ferrules, splices air lines, etc. but until then I've had to use a lighter quite a few times.

The hot oil in an old fryer where you can control the temperature will allow a more uniform heat.

You don't want to use a lighter to heat it to slip it over the fittings. Use either the hot oil method you described or a heatgun. I doubt seriously you would even need to clamp it.
