Questions about replacing fuel lines?
My truck is a 2000 Freightliner FLD120, Series 60 Detroit with 1.3 million miles on the truck.
Lately I've noticed when pulling hills I will get "power surges", almost like I have normal full power, then I lose a little, then it comes back. I think the old fuel lines might have something to do with this problem.
Should I replace the existing lines with bigger diameter lines? Will that do me any good? Any other ideas regarding my power surges?
Is this a worthwhile discussion?
