Guys-
I had my rear passenger side CTIS flexible line develop a leak. It was a pretty good size hole. I am in the process of replacing it but the OEM ones are pretty expensive. What alternatives do I have? What could fit the connections that could be picked up at a local auto store? It looks like a 3/8" NPT connector. Any ideas would be appreciated.

Which CTIS line? The one from the hub to the wheel with the quick disconnect on it or one of the other ones. The older trucks had plastic air lines. They work fine but expand some when airing up tires. Because of that they are slower than the metal lines. I can't remember if the connector is 3/8" or 1/4".

 

It was one of the other ones, not from hub to wheel/quick disconnect. I suppose I will get some hard plastic air lines and run new lines. Thanks!

 

Yes, I recently had some damage to mine, online they are about $120. I went to the hose store in town, they made me one, with slightly different fittings but still the main connections are 3/8 NPT. Worked like a charm and I don't have to listen to the low air alarm any more. Oh ya, it only cost me $40

 

Sorry I actually think it was 1/4 NPT.

 

I ended up going to NAPA and getting the 3/8" DOT air brake lines. They had all the fittings i needed. Once I replaced the broken rear right the rear left began to leak. Just yesterday I swapped that out for a new one. I put it into service and the main line began to hiss. At this rate I will end up replacing all of them!
