Well, looks like I may have put off fuel line replacement a little too long. Apparently I have a leak in at least two lins and none of the existing lines look good. I'm not going to be able to drive the coach to NAC as I had intended to do so need to source the parts. While I've found plenty of info on the Parker HTFL fuel lines, I haven't located a source to actually purchase from. Does anyone know where I can buy the lines and fittings? I'm willing to buy in bulk if others would be interested also. I want to bite the bullet and install lines for engine and genset, and at the same time replace coolant lines to front. Appreciate any info. Chuck

Chuck, don't know if this'll be of much help but here are a couple of images of my invoice for the fuel line replacement which gives quantities of fittings and hose part numbers. As well as the labor cost you will save when you do this yourself :-)
Edit: added a picture of my old fuel lines to show condition... The line shown in the picture is one of the main fuel lines which wasn't actually exhibiting any symptoms as yet.
Any hydraulic hose shop can make new fuel hoses.
Don, thanks for the fuel line details, very helpful. Pamela and Mike, appreciate the source, I'll be giving them a call.
I had a call in to Foretravel and Billy Jack called me back, I was inquiring about a fuel line "kit". No go on that according to Billy J, says the technicians make multiple trips to the parts counter on each job as each coach is somewhat individual. Asked why they were using the new lines and he said, "well, the lifespan on these coaches is so long we're trying to avoid having the same problem down the road." All in all, very helpful, said to plan on finding a mix of JIC, pipe and tube sizes. FT happy to sell any parts but I will need to spec.
Looking at the Parker info is very confusing, for the brown HTFL which is a high temp fuel line, nylon, they spec one fitting as suitable for use with it. This is the NTA compression style fitting. Looking at the NTA fittings they say "not for diesel fuel." So, I'm going to rely on a good industrial supply co to help sort this out.
Don,
I'm looking at the info too, so thanks for posting the details. Always appreciate your technical posts.
Here are a couple of links to the HTFL tubing and the recommended Parker Prestomatic diesel fuel fittings.
