About fuel lines Question.

[Jeff H]

I heard the rubber fuel lines can suck in air when they go bad. I don't get why they don't leak any liquid though?

It's a Daimler-Chrysler gremlin..... we don't ask 'why?', we just make it better.



I'll live though all of DC's shortcomings for my Cummins... . it's a VERY small price to pay for what we get in the long run.

It will if you let it go long enough!



The consensous is that the lines were painted and subjected to high heat that causes the enventual cracking. Also the return line is under low pressure and is basically a drain back line.



Its a fun job that even more fun when you are paid to change it! You wonder who indexes the little clamps in such a hard position.



You might find it easier to remove the starter (10 mm 12 pt. )

Remove the fuel filter to get at the line on the top side. On the bottom gently pull on the line to be able to get you 6mm socket on the clamp. I use a utility knige with a new blade to cut the line so it pulls off easy and doesn't damage the soft steel line that it attaches to.



Find some good rated 5/16" fuel line buy 24" just in case Mr. Murphy shows up.



Also refer to the current issue of the TDR ref. p19 and Jim Anderson's arcticle for other worn rubber parts in the fuel delivery system.



Good luck
