Air filter air duct

[cncjim]

On my 05 Monaco Camelot with the 400 Cummins engine I have a ecolite air filter. This has a 6" dia. flexible duct from the filter to the air intake top rear drivers side. Has anybody replaced this duct? if so what did you use and where did you get it from? Monaco does not have a replacement. I can buy something similar in 25" lenght at $12.70 per ft. plus shipping but there has to be a cheaper way. Also anybody replaced the radiater surge tank?

It's all here. The top end of mine is aluminum tube. You may only need a few feet at the bottom???

Thanks Twomed,
I spoke to Donaldson yesterday and they gave me several phone numbers to call, in fact I spent several hours tracking this stuff down finally Monaco came up with the original manufacturer.The original ducting is no longer made but the equivalent like I say can only be bought in 25ft lengths. I'm off to Freightliner just now to buy a 6" air filter right angle hose. then to the local stove and fireplace shop to buy a short piece of 6" pipe. with any luck this will fix it till the rest of the ducting rots off.
