Reading the post can be a knowledgeable lesson when faced with something that needs addressed such as fuel lines. But at the same time it can make one wonder about his new to him coach may also have the same need to replace his 2001 fuel lines.

Is fuel line replacement something that should be considered as preventive maintenance or just wait til there is a issue.

Glad you found a hose that makes you happy, and you didn't get hosed (pun intended)
So your sending me the difference you saved. ...LOL
Cheers

Greg, et al;

Two reasons to change fuel hoses:

1. Engine performance issues (sucking AIR).
2. Visual inspection reveals significant cracks-- look at the hose going into the primary fuel filter-- easy to see and pretty indicative of hose condition.

Ya, their is a third reason-- you didn't do it and you are on the side of the road-- your engine demanding diesel and you are feeding it only AIR.

Brett, I would argue that there is indeed a third reason, and that is someone installed the wrong damn hose and you now have a part that could fail when you least expect it. Also the fact the diesel is permeating thru the hose and the smell is throughout the coach.
Would be no different if they installed the wrong air filter or air dryer, or tires. Correct the mistake. And that is the reason I am doing it.

Cracks are hard to see in old hoses. Pick a spot near the primary fuel filter and bend it as much as you can. Lots of little cracks showing tell you you're on borrowed time. Difficulty in starting first time in a while is often the first sign of fuel hose degradation.

Indeed, our generator fuel hose had literally millions of tiny cracks. Cracks that you needed strong set of glasses to see and like Amos said, you have to bend it to see them. The big tell tale was that it was damp, not wet itn about a one foot area.

Bob, the hose is not going to just fail suddenly. Usually the symptoms are lack of full power when going onto the freeway or harder starting than normal. Good to check out the hose before it gets bad enough to strand you when your coach does not start in the morning. The smell may be coming from a damp area in the hose. There are quite a few spots that will be hard to get access for a visual inspection. You could also clamp off the hose at the tank and then use a MityVac at the engine to check for leaks.

Diesel is a bad smell but auto gasoline is much much worse.

Pierce, on my last boat, a 40 foot Endeavour center cockpit, on the survey we found a strong diesel smell in the bilge. I questioned it, but my surverour, one who I had a lot of trust in, from other surveys, said don't worry about it, just use the boat. But I am not that kind of guy, new there was a leak somewhere, and had to fix it.
I pulled the 75 gallon aluminum tank, under the 50 HP Perkins diesel, which was a bitch to do. There were tens to a hundred small holes in the tank, as it had been sitting in bilge water for over 20 years. Cost me a ton of cash to have a new tank fabricated, by Florida Marine tanks, the same company that builds Foretravel tanks, and the Endeavour tanks. But it was worth it. The smell was gone, I was happy about it. New filters, hose etc. Was the right thing to do.
First home I purchased in Corpus Christi, I smelled gas. House had a commercial stove in the kitchen. Weighed hundreds of pounds. The inspector said no leak, the owner said no leak. I smelled it though. After closing, I disassembled that stove, pulled it from the wall, and found the leak. Now that leak could have been there for a long time. Maybe it would have been fine. But I am sensitive to that type of smell, and can't stand it, and would have worried over and over that one day the house would have blown up. I fixed it.
So to me its about safety and doing the right thing. Sure that hose might be fine, except for the smell. Or maybe not. But can't have it on my rig. Got to go..... But that hose isn't meant for diesel so the entire hose stinks. Its coming thru the rubber. The business that put that hose in should be held accountable. But it was 2 owners ago. I could call them and fight it out, but its not worth my sanity. So I will just fix it. And thanks to all on this forum that helped by posting their experience doing it as well.

Curious about whether you considered using OEM quality Aeroquip wire reinforced hose rather than the fabric reinforced hose?

Bob, yes, the diesel smell can drive you crazy. I permeates everything. I was just suggesting it would not likely fail if you were on a trip.

In sailing a new sailboat from Hong Kong to Manila, the prop shaft leaked and there was quite a bit of salt water in the bilge. In the 8 days it took for the voyage, electrolysis ate several holes in the mild steel tank. I had ordered a stainless tank like the water tank was but they would not fit it. I installed two Racor 200s in HK and had to drain them every time I used the engine. I pulled the tank when back in the U.S., welded plates over the holes, used fuel tank slushing compound inside and covered the outside with FG cloth and epoxy resin. No problems after that.

Our main hoses are OEM late 1992. Keeping fingers crossed.

Bet you were glad to part company with the Perkins. I sure was.

Hopefully this is not a hijack but the smell thing is very important to us. DW is sensitive.

Noticed driving up to a campground in the mountains around Los Angeles I get a strong diesel smell.

Twisty turny road. Not creeping speedsise. Driving fairly aggressively on the turns.

Full tank minus 20 gallons max at the bottom.

Vented gas caps.

Am I supposed to smell fuel? Straight road. Hills. No smell. Only hard cornering at speed for a 15 mile stretch.

Thanks for any feedback

My x Foretravel mechanic buddy used the Parker hose and put hose clamps on the ends.

Are the Foretravel tanks fitting barbed?

The tank fittings on mine were barbed. I reused them no problems.

Chuck if I could use OEM quality hose I would. Haven't been able to find any that I could afford. Locally they only sell it by the roll.
Looked online as well.
The Trident hose I purchased will be more than fine, the price was right, and I was able to get it by the foot for most of it and at a good price with free or little shipping and no tax. Time will tell if it was the right decision.

Dorman says that Their tubing is sound for bio diesel ; No mention in the tech description , but a fast answer from their tech line states diesel use.

The PA12 and Nylon 12 are designed for all fuels it look like . If anyone can find data that states else wise ,please share.
