new fuel causes leaks?
Hi all. Some really old guy here....I have a leakage problem.
I am referring to fuel, not body fluids. Both the 1986 6.9 diesels I have had developed serious engine fuel leaks shortly after using the new low sulfur fuels.
Is this a coincidence? any help greatly appreciated

thanks ....its just that I have noticed that the rubber fuel parts seem to be dissolving or breaking down as there is a lot of black material that comes off from inside the fuel return hoses and off the old o rings when you wipe em with a rag. Donno craig-z

The new Ultra low sulfur fuels might degrade old fuel lines and "O"rings. Biodiesel will also do the same. If you haven't changed the fuel return lines and O rings in the last 10 years then you have parts designed for the high sulfur fuels.

yes leakage has been an issue since the changeover , the new fuel can migrate where the old wouldnt
also the new fuel doesnt have the lubricity that high sulfur did

thought I wuz losin my mind....
I have suspected such a thing for a long time.....i had a heckuva time with the old gas powered vehicles that run on leaded and the unleaded dissolved/dried out all the rubber fuel lines, etc. GRRR, (again)....I especially loved changing the now rotted hoses on top of the gas tanks and now THIS.....ahhhhhhhhhhhhhh!!!
