We had a roadside breakdown outside Yuma in March. A 12' rear heater hose split at the connection point up under the bed area (Goes to bedroom heater). Has anyone replaced the long heater hoses by themselves that run from back to front of the MH? I'm probably going to have those replaced this summer since they are 12 yrs old. Is it a DIY project?

I've been looking at mine and consider it a DIY, but can't say about a Spartan chassis. With the cargo bays empty, I can open the along the frame boxes that contain the chassis wiring, and heater hoses/ A/C lines. Tight spot is along side the fuel tank. I have purchased 5/8" brass connectors to attach the new hose to the old and feed the new hose in to the area from the rear while a helper pulls the old out from the front.

On our 04 Essex I replaced all heater hose because in the first 2 years we had 3 times heater hoses burst in the cabinets below. Problem was wrong hose was used standard grade. There were 6 sets of hoses run up to the front of the Essex in the frame. Used marine grade hose with shut off valves at all connections. Over 200 feet of hose with all connections around 900$ for supplies and 40 hours of labor. If your 1 hose is leaking should replace all.

OUCH: Big time ouch. My lines have shut off valves beside the trans, 5' from the engine to the valves, then are continuous to the heater valve at the front, then 2x 6" to the core. 80' total. Guess I'm luck it's not equipped with rear aux. heat and engine aid to the hot water heater.

your lines probably have many retaining brackets to keep them in place. Would be difficult to just pull them from one end to the other.

Luckily , I have access to the hose from the trans to the back of the fuel tank; the area requiring the pull though ; is the 5' where they run along side the tank and I can see that there are no hangers in that area.

I changed mine myself it was hard to pull them along the water tanks in the frame Newmar said just change from engine to the hydro hot as those are the only ones that had the wrong kind of hose idk?

On our 04 Essex all the heater hoses were the standard grade and we had both Hydro-Hot and dash heater burst on us. Replace all heater hoses with green strip marine grade hose.
