Gergwheel1647545492 Posted August 26, 2018 Report Share Posted August 26, 2018 I have an 03 Silverado extended cab 4x4 v8 truck. Fuel lines are leaking. I bought new OEM AC Delco hard lines and after looking at the lines and the truck I guess you either lift the cab or have to drop the transmission. Looking into other options to avoid that much work. I came across this set on eBay. Anyone have experience with flexible nylon lines that you cut to size? Just worried about the lines rubbing something and getting holes after a couple years. http://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F271771654819 Quote Link to comment Share on other sites More sharing options...
Cordell Posted August 26, 2018 Report Share Posted August 26, 2018 I would not use nylon lines, they'll work but make for a sloppy install and god forbid they get loose and get cut or pinched. It's just asking for trouble. I would consider the aftermarket lines RockAuto sells. I used them on both my Cobalts, very easy install as they come is a couple sections, and they work just fine. https://www.rockauto.com/en/catalog/chevrolet,2003,silverado+1500,5.3l+v8,1412086,fuel+&+air,fuel+line+/+hose,11224 Quote Link to comment Share on other sites More sharing options...
cdk 4219 Posted August 27, 2018 Report Share Posted August 27, 2018 You can get them on with some swearing and slight bending of the hard lines. Not fun , I did it on a 4 post lift. More difficult than the brake lines. You would be better off going with aeroquip fuel line than the nylon, the nylon seems like it would bend well, if it doesn’t hold its shape and has a mind of its own.

starkmaster03 Posted August 27, 2018 Report Share Posted August 27, 2018 I've done three sets on three 00-05 Silverado's. I've always ordered the ones from Summit that are like $90 for all stainless for everything. It's more of a pain but I think it's worth doing once.

zeitgeist57 Posted August 27, 2018 Report Share Posted August 27, 2018 Chad, can you share a link for the $90 fuel lines? https://www.summitracing.com/parts/rnb-919-814 Looking up 4.3L V6 Silverado fuel systems I’m finding cheap brake line kits in Stainless Steel, but the fuel line kit is $200+ Quote Link to comment Share on other sites More sharing options...
Green Bastard Posted August 27, 2018 Report Share Posted August 27, 2018 I just did them in my 03 Avalanche earlier in the summer (on jackstands, what a pain). The top nut that holds them on at the top of the transmission is the biggest pain in the ass. I used a bunch of extensions and a good flex joint (wrapping it with a little electrical tape helps). Take down the front driveshaft and the transmission crossmember to get the access you need. Also, be careful if you have the abs unit on the framerail like I do. You will have to move it, but if the brake lines look fragile then plan to do those too. Quote Link to comment Share on other sites More sharing options...

Looks like they went down in price as well >$70 for pre-bent SS lines. Quote Link to comment Share on other sites More sharing options...
Gergwheel1647545492 Posted August 28, 2018 Author Report Share Posted August 28, 2018 Sounds like Chad is talking about brake lines and Clay and I are both looking for fuel line help! Quote Link to comment Share on other sites More sharing options...
aussiek2000 Posted August 28, 2018 Report Share Posted August 28, 2018 You don't have to drop the trans. But Getting the lines around the torsion bar crossmember and around ABS unit is a pain in the ass. Much easier job if you are going brake lines at the same time Quote Link to comment Share on other sites More sharing options...
zeitgeist57 Posted August 28, 2018 Report Share Posted August 28, 2018 Sounds like Chad is talking about brake lines and Clay and I are both looking for fuel line help! My teeruk is solid, but surface rust is showing up on my lines - both fuel and brakes. 79k miles on a 2001 and it looks like a matter of time over mileage before one goes pop.

But Getting the lines around the torsion bar crossmember and around ABS unit is a pain in the ass. Much easier job if you are going brake lines at the same time I didn't mean to drop the trans all the way out, just remove the crossmember so you can tilt the motor back. Mostly just to make it possible to get to the nut at the top of the trans that holds the fuel lines. Quote Link to comment Share on other sites More sharing options...
Mojoe Posted August 29, 2018 Report Share Posted August 29, 2018 How many of us have these damn trucks? Old school CR is fun of tow pigs now. I had a hard time finding SS brake lines and had by buddy find them and put them on. All I know is we are still messing with it. I'll update when I get my truck back.

Another truck I was going intake gaskets at the same time. Made it much easier to do the fuel lines. Quote Link to comment Share on other sites More sharing options...

Ops, not sure how I got that far off base. I did do SS fuel lines to my truck as well but it’s the Duramax so I won’t be much help with suggestions on that.

Rocky31186 Posted September 8, 2018 Report Share Posted September 8, 2018 I just finished up fuel lines on a 2004 avalanche, very similar. It was a pain, but use a swivel and a few extensions and you can get the bracket off. You will have to bend the new lines to get it back in.
