Well, the inevitable happened. I've got rusted fuel lines on my '03 Savana 3500 1-ton gasoline work truck.
Heading to the parts counter tomorrow(or tuesday), but I have a really bad feeling that they're going to tell me that they're all discontinued, because I've already poked around on the web, and can't find a kit anywhere.
...With that in mind- what do you guys do when you can't get OEM lines? Is there any safe and suitable replacement out there?

It looked great in theory, but nothing there for my vehicle :-(

Hmmm.....Interesting idea... The two steel lines that are rusty and wet run up to the topside of the gas tank, so I see a tank drop in my near future, lol. I've attached a couple of pictures, so you can see my predicament. both of them appear to be steel up and over the tank, but have flex fittings in them elsewhere, so I'm not sure exactly how to handle that- but I'm sure it'll be a lot easier to sort with the tank out of the way. I hate pulling tanks, but it is what it is...


Bad steel to flex line...

Up and over the top of the tank...

These two gotta go...

 

they also make plastic to steel, steel to steel, plastic to plastic unions specifically for fuel lines if you need to section lines together

 

You might ask a dealership service dept what they charge and do to correct this problem, and go from there. There is all kinds of special tubing and fittings to do this only you probably will not find this info on the net. .

 

Disconnect the lines take some measurements and head over to summitracing.com. You can get adapters from the click connect tubing end to AN fittings. Then put together hoses to replace. Because of all the ethanol in fuel these days you likely want to get flexible lines that are PTFE lined. Just make sure you get hose ends that match.

This might be what you need but please verify!

Okay, so I found a place called LinesToGo on the web. While they don't have a full line set, they did have these:

2003 GMC Savana Series 6.0L Fuel Lines | GMC Savana Feed Lines - LinesToGo

...As far as I can tell, there are only two steel lines running up and over the tank, so these may be the ones. Has anyone pulled a tank on one of these and can confirm that there are only two steel lines going up there? I asked the same thing of LinesToGo, but I'm not sure if they'll be able to answer that accurately, and since they're pretty expensive, I'm going to try and confirm that before ordering. If I can't confirm that, then I'll be spending a lot more $ in tools to fabricate my own lines, but it is what it is...
