Can't find replacement for cut dash A/C hose

Hi I have a 2002Coachmen Mirada on a 2001 F53 chassis. I have a leak where the low pressure hose has been cut by the edge of the radiator over time. Poor design I guess. I have never replaced an A?C hose but this one looks like 2 nuts and some fishing and done. I know I will need to find a vacuum pump to test it before recharging. I should be able to do that. Problem is I cannot find a replacement hose. I am seeing a hundred people offering me the wrong hose for $40. Ford has a hose for nearly $200 but no picture so I an hesitant to buy that. I am not even certain who made that unit. Any suggestions?
Here are pics







I did check this company but could not figure out which one I need.

https://www.comfortairgr.com/product...rome-rv-parts/ so I sent an inquiry.
Here is the Ford part
2001 Ford F53 Compressor to Condenser Tube | FordParts.com

Anything you can do to point me in the right direction would be great!

Call a local automotive A/C repair shop and ask them if they know of a place local that makes up custom A/C hoses. There is nothing special about this A/C hose. Find a place that makes them and take your old hose to them to use as a pattern. Or you could buy a splice kit and cut out the old damaged section and splice in a new piece of hose.

Your A/C unit is probably an Evans Tempcon.


By the way, if this unit has been out of Freon for more than a few days you will need to replace the receiver dryer. Otherwise the dryer element may disintegrate and clog up the system.

Thanks. I probably would buy the Tempcon if they sell it since I'd have to take it off in any event. I'll send them a request and see. Otherwise I would splice. After I saw your post I did some checking. I saw splices that used a barbed fitting and hose clamps and others from Airsept that had crimps and a blue frame that looked better. I can't tell if I need a special tool though. Have you done any of these? Would screw type hose clamps really hold do you think?

Go to any auto parts place and buy the barb hose splices. They sell them and they are easy to install.

The crimp sleeves on the ends can easily, and carefully be slit and peeled off, then the hose can be cut off the end fittings. A good shop with bulk barrier hose and crimp sleeves (or hose clamps) can repair it, you don't even need new fittings, just the proper barrier hose used for Freon 134A.

It's the low pressure hose, any A/C place can make one. You can use the old hose but a high likelyhood that it will leak.

I make my own hose using this https://www.mastercool.com/product/71500/ You may find an off brand for less or Craigslist.

Alternate idea..

This hose needs to handle at least 200 psi. This could be the pressure in the hose on a very hot day without the engine running..

A hydraulic hose shop may be able to crimp a straight through fitting on the cut ends to re-connect them.

I have access to aircraft AN hose fittings. I'd install a male fitting on one side of the cut, a female on the other side, and screw them together.

A regular ole barbed fitting might be able to handle the pressure. Use a couple fuel injection clamp on each side of the barb if you try the barb fitting

As others have said, a/c hoses like that are generally made to order. Too many different sizes and shape to do otherwise. Most any local a/c place or hydraulic shop will either have the capability to make one or will know who does.

Thanks all. Sounds good. Since it is the low side perhaps the barbs with 2 clamps on each side would work. If not then I'll but the one that usus the big assed crimping tool and ask my neighbor (does home AC sales and service) if he can crimp them. The hose didn't leak due to decay but it was installed up against a rough edge of the radiator(Thanks Coachmen) and cut through. It took 100,000 miles to saw into it but it did. I'll check the hose out before reusing it though. I need to find a vacuum pump before I can fill it but I'll let you know how it worked! I'll let you know how it worked!
Thanks again! This must have happened to many people or it will soon.

Kahoona - I think I told you about this one before??

Check the large hose that comes out the bottom of the power steering reservoir and goes to the pump. Where it passes through the radiator support panel, mine had a very sharp kink in it that was cutting off flow to the pump.

You cant see the kink because there is a net cover thing on the hose but if its making a sharp turn, its probably kinked.

Hydro-boost brake pedal occasionally pulsing – 2001 Coachmen Mirada 300QB

I checked my Southwind and its ok.

You should be able to get by without pumping it down.

Hook your can up to the service port and put a little bit in, just enough to pressurize the system. Then open the shrader valve for a few seconds to purge it all out. do this a couple times. Don't tell the EPA I said to do this.

Given the age of the system you definitely want to replace the receiver dryer while doing the hose repair, otherwise bad things can and often do happen.

Actually I think I will do that. If I can get the ends off I can take it there then find a vacuum pump and finish the job myself. Probably the best compromise between cost and safety. Thanks.
