fuel line replacement

Hello, just viewed your post , I am searching for fuel lines for my 02 avalanche Z71, do you know of any companies the make a kit, preferably stainless steel..?
Thank you
 
You'll likely want to contact your local dealer to make sure you get everything you're looking for. PN wise. Pst that, GM is actually one of the only sources for a full kit. I know dorman makes pieces here or there, but even on rock auto, most of the fuel line kits are still GM direct.

Depending on who you're going to have doing the labor, you can shop around. Rock auto has a kit, if its the one you need, which is apparently different than newer models (like seemingly everything else on a 2002..). You can use sites like gmpartsdirect.com. Check your dealer direct pricing, as well as check to see if they have an online parts store. (search *dealer name* parts, and you'll ususally find it) and check the prices there. I've had prices be half of the in person values and the parts manager has simply price matched it.

Other than being a 20 year old model they also have a external inline fuel filter. So they are a little hard to find a complete kit.

A couple of places that may have them inline tube or classic tube. The place I got a set from was not even in the United States

I got the brake lines that over the rear axle, the ones that NOBODY seems to carry, from here https://www.inlinetube.com/ While I have yet to install them, they do appear to be of god quality and, when I held them up to the axle, all the bends seemed to be just like OEM.
 
Yes, thanks
I also used that company for my brake lines, I replaced them all a few years ago with stainless steel, they are very good quality and are holding up very well.
I just couldn't remember the company at the time..
I called them again yesterday, they gave me a price of approximately 450.00 complete with every gas line, all stainless.
Its going to be another big project and big money, quess Im going to purchase them and then build up some ambition and start replacing them...
 
450 is the going price for a complete set.
 
inline tube also has a full set of flexible nylon fuel lines, has anyone used these? if routing stiff fuel lines sucks as much as routing stiff brake lines, ill go for the flexible ones. anything is better than the rusty steel lines currently there.

plus the flexible lines are only $160 for the whole kit.

plus the flexible lines are only $160 for lines and expect them to hold up to exhaust heat, road chemicals and pressures of an ABS system etc.
I personally don't want cheaper quality lines under my AV, sometimes you get what you pay for......

longevity is with SS Tubing
 
Are flexible nylon fuel lines really "cheaper quality" than SS? I don't know. Sometimes the newer materials technology is actually better but it is hard for us old timers to accept. Just wondering as I haven't researched this. To me, if I can have a flexible line that holds the same pressure, won't degrade from fuel, heat or other chemicals and has the benefit of not rusting, I would prefer that (as long as it will hold up to any possible "rub" points and not wear a hole--if there are any rub points).
 
ill let everyone know! the flexible lines shipped yesterday. i figured i can replace the flex lines 3 times for the same cost as i was seeing for the rigid stainless lines.

based on what the website shows, they are all wrapped in what looks like a wire loom, which im sure helps with "rub" points.

Looking forward to your follow-up and some pics if you can. I need to do mine at some point.

Not sure if any line gets close to the exhaust or manifold, that would be the key points to keep away.

ill try to remember to take some pics as i go.

the fuel rail connects to the line near the back of the block, and the lines follow the trans tunnel down, then hop over to the frame rail. i dont remember it currently being very close to the exhaust, but ill make sure the flex line is away from it.
 
alright, i forgot to take ANY pics along the way. but to document it for future searches...

the rear drive shaft had to come out for fuel tank removal, and the rear tank strap was rusted so bad it came out in 3 pieces. luckily one of the local parts stores had them in stock.

As far as the flex nylon fuel lines go, they seemed very well built and were plenty long. It was a blessing to only have to work with brand new quick connect fittings and no rusty lines. The main line is 2 pieces, tank to filter, and filter to fuel rail. The return line goes from fuel rail to tank. And the vent line goes from the back side of the drivers side head, to the charcoal canister. I left the old stainless lines in the truck, to use as an anchor to zip tie the new flex lines away from things that are hot and/or spinning. Removing the front drive haft opens up a lot of room to route the new lines up the firewall. The whole job took about 10 hours total, but I'm no speed demon. just glad its fixed, runs great, and no leaks.
 
Excellent, thanks for the update. I guess when I do mine I'll throw in a new fuel pump unless the pump goes first then I'll throw in the fuel lines when I do the pump :)
