Leaking Fuel Line

[dougs01gt]

I have a question about the fuel line in my 2000 5.3. There are 3 fuel lines i believe coming

from and going to the tank. 2 of the smaller ones are rusted on a 90* turn in the pipe. Instead

of replacing the line which looks like a pain can i cut the rusted section out and use a

rubber line with clamps??

 

Thanks

You can try it if you get fuel inj hose not reg fuel line because fuel inj hose is reinforced and if your gonna clamp it be sure to double clamp it. Not positive it will work where as im not sure how much pressure is in those lines but it worked for me in my 94. Goodluck

Ok. It seems like the easiest fix. I dont believe its the main fuel line. I believe its one of the smaller ones but i need to check

and make sure.

Anyone else have thoughts on this??

It's worked for me on a couple of vehicles but not the best repair method as the hose detiorates over time. Keep in mind the pressurized line from the tank has @ 60psi. so use a braided reinforced hose rated for gasoline and liberal overlap for clamping.

 

A better repair is to cut the bad section out and have a metal replacement section bent to fit. Metal couplings are available to join these sections. Worth the extra effort if intending to keep the vehicle.

My local parts store have section metal fuel line in the "HELP" brand section. You'll need to get a pipe cutter and pipe bender (prob $20 total) and bend it to fit. I did this near my fuel filter and it worked great. They come in 2 sizes, make sure you measure before you go so you wont have to make another trip (like I did).

I see that this thread is really old, but I don't know if y'all get like notifications or something...

either way, I've been running into problems with all sorts of lines on my '97 sierra. I had to replace a brake line after I slammed on the brakes real hard... so i decided I should replace those, lest it happen again. A little closer to topic, I tried breaking off the fuel filter with no luck, multiple wrenchs, lubricants, bangs, randomness, no luck. So i figure I'll replace all the lines from tank to rail, whats the best way to go about that, I don't want my fuel pump dying tomorrow. Do they sell pre-measured stuff or do I do that with a cutter and bender? My skills with a flaring tool need some practice. Also should I replace the pump or anything else while i'm in so deep? I hear they go bad quick like! I have 120,000 miles now and I wanna run her till she quits, so I'll put money where its necessary for the longer life.

oh yeah, and I've gotten several random misfire codes recently on a road trip, my guess is the fuel system is all sorts of weird.

 

Thanks a lot,
