It's not a question of in stock, it's a question of price.

I have a heater box as well in the back, probably the 3rd row toward the back. I really want to save this heater and am kicking around how to move it and reroute it. Thanks for this thread!
On the other hand, it's really only used when the bus is rolling am I right? Or if stationary I'd obviously have to run the bus... Maybe I'm over thinking this as I'm going to have an alternative what source when I'm parked. Thoughts?

You could use it when parked if you have a diesel coolant heater.

That said, the better way to use a diesel heater is to get one that uses blown-air heating.

we replaced all the hose with 5/8ths inch but now I need to connect the new hose to the old hose and then at some point to the heater again. we will move the loop to the end of the new hoses until we get to the heater replacement/hook up. **** I just realized we either need a new 5/8th loop or reducers for that end as well unless we wait until we hook the heater up. AUGH.

so I have looked on line and I don't see what I need to connect the old 1"ID hose to the new 5/8th ID hose. The hose runs along the floor under the step at the emergency door and over the wheel wells and I am going to shove some rubber and or insulation at all the points where it could rub.

The quick connect style cheapo plastic things are NOT what I want to use. I want something that should hold up for a LONG time. can you suggest a specific product? Brass plumbing reducer maybe? any advice would be very appreciated.

You're asking for a double step down, not a common reducer. There are 3/4"-1" brass hose barb if you had gone with a next step down instead of 2. You could then get a 3/4"-5/8" hose barb to step it down to 5/8.

I have see brass tube connectors for heater lines used in bus applications, listed in online bus supply/parts stores, many different shapes and sizes. also.. when running a line, why use the line itself as a radiant heater? so in stead of rubber hoses use some thing like a finned tube like what can be found here Finned Tubes, Fin Tube & Finned Pipe Manufacturer - Wadsworth, Ohio

Thank you!! I have plenty of extra hose to put in two steps and I am going to leave them accessible so I can make sure they are holding up well.
