Engine/Transmission (1994 - 1998) Fuel line help

[scotty-u]

My 94 has developed a problem that I think is related to air in the fuel (hole in the fuel line). After startup, once I am moving, the truck exhibits low power and also has a miss (like it runs momentarily after a FF change), which clears out once I light foot it and grab fourth gear.



I have read about replacing the rubber portions of the fuel lines, and plan to do so. After I crawled under the truck, it looks like I have braided SS fuel lines from the steel lines to the engine. One line has what looks like a two-tab fitting, and the other is a direct crimp onto the steel line.



Are these original lines? Both braided lines look to be the same diameter from the outside, as do the steel lines. The rubber lines at the tank look to be original. Fuel filter and air filter are due to be changed, and no work has been done on the truck. No fuel leaks either.



Your thoughts and comments, please. Thanks. Scott

Yes, it's all normal/standard, and unless it's been replaced - original.



How is your fuel gauge reading/working?



I ask because a former long time poster (who moved on to other places years ago) recommended replacing the fuel line all the way back to the tank because that was easier than fiddling with the connections at the back of the engine in the area where your fingers needed a few more knuckles to reach all the stuff.



When I did it, I opted to go even further - I lifted the front of the bed enough to let me fix a few issues at the tank at the same time. I replaced the fuel gauge sending unit in the tank, replaced the leaking gasket at the top of the tank (that spewed fuel every time I full-tanked) and routed the lines to the tank.



You can do the fuel lines without lifting the bed - that's only to give access to the sending unit, and there used to be about 2 dozen articles from guys who did the same thing and gave directions and photos.



But think about how far back you want to go with the repair.



On a side note, I had to drop the tank about 2 years later to route a new brake line from the master all the way back to the rear axle. I've got to say that they were both about the same amount of work.



Do some poking around, look to see whats involved, what you can reach, etc. It's not a "hard" job, but it IS a PITA when you realize it was built by elves with much smaller hands.



Good luck.
