I have a hydraulic hose that is starting to leak, it is above the propane tank and part of the HWH slide system. I can't follow the hose under the coach because it pretty well hidden above the fuel tank. I have found that on the hydraulic pump and where the leak is that the part # is the same.
I have a couple pics and just wondering if anyone knows if these are the same hose, I can't find any diagrams of how the system works.

Having trouble with pic

HWH incorporates hose length into their part numbers so the same part number at both ends doesn't always guarantee its the same hose. Need to confirm which solenoid port [in and out] on the pump powers which slide. The next challenge is replacement--coach manufacturers often run and plastic tie the hoses along/inside the frame during the build process. Accordingly, you sometimes have to abandon the OEM hose in place and find an alternative route for the replacement hose. This can make it really tough to estimate length for the new hose. In this case, its better if the new hose is a foot too long, rather than an inch too short!!!![smile]....
PS--an 1/8 to a one facet turn on a connection [use two wrenches] can sometimes stop a small leak, if its in the connection and not the hose material. But don't over tighten beyond this point.

I have tried to tighten it, it's pretty tight. I might try disconnecting both ends of it and blow through to see if it is the same one. it is the only hose I find that is marked the same length.

The hose that HWH used back in our era coaches would weep causing a mess. The burst strength was approx 4 times the operating pressure so no worry about a hose rupturing. Those hoses were farmed out for manufacture but with the problem, HWH took hose manufacture back in house. At one time, there was a guy that re-terminated the hoses if they leaked at a connection I was fortunate enough to have HWH replace all my hoses in the coach at no charge back in '02.

Somewhere there is a diagram of how the hoses are routed. I think it is in one of the 3" binders that came with the coach.

If you are going to disconnect the hose, have some caps handy else you will have oil everywhere. Good thing is that the system is self bleeding when you get it back together

My Country Coach HWH fittings were leaking at the same place. NO way to stop that leak. I ended up pulling the defective hoses, all inconveniently located, took them to NAPA AUTO and had new lines made up. All in all a PITA.
Total cost was about $120.00

If I had to do it again I would.
Front DS dual ram slide.

Good luck

That hose has some slack so get out the phone book and look up heavy equipment repair as this is a very common problem and the solution is portable hose crimpers.

One huge note here is the hose manufacturer is critical to the fitting manufacturer.

Hose a with fitting b causes exactly what you have.

So before doing anything look close at the hose to get the manufacturer part number or other identifying information then when calling places ask if they are correctly tooled up for that brand of hose and have same brand of fittings.

Avoid "Universal" at all costs.

If it is say a Parker hose then the fittings need to be Parker too.

Contact hose manufacturer to order correct fitting if needed as well as asking who in your area is authorized.

We learned this while doing bobcat work...little thing they usually do not tell you...

Had this exact same line leak on my 02 Intrigue. You are correct as your pictures show they are the same line.

I cut off all the zip ties, then slowly took off each end. Was then able to pull it through, but before doing so I attached a small chain to one end.

Took the old line in to have a new one made up. Attached the new line to the chain and pulled the new line through. I did have to get underneath the coach once to clear a jam on the way back through.

After replacing the line I ran the slide out three times. First time was a little jerky then the second was better, third time was smooth.

The new line does have different fittings than what are on the others, but works just as good.
