Main tank for air bags

Hi all

I am new here and new to RV's in general.
I just got a 1988 Winnebago Elandan 32ft. It seems the previous owner did not blow the water out of the main pressure tank the feeds the rear air bags and now it has a hole in it. It has the auto level system, the control box under the dash has three levers. Auto/man, left-up and down, rightup and down. The compresser is running and I can feel the air comming right out of the hole. Do any of you know where I can find a useable replacement tank that will fit??

It depends on the operating pressure and size of the tank. You could try the manufacturer or an air compressor service and repair place. A thought does occur to me though. What if you welded up the hole or put a screw with some sealant in it? Then you could test the system to see if it works OK before investing in a new tank.

We're just talking about an air tank, right? Any tank should due that is designed for compressor pressure. On the airbags on my Class-A (aftermarket, firestone) - I think the compressor will do 100psi, the bags are rated for 85 psi.

If it was my rig, I'd just go down and pickup an air tank (even Harbor freight carries them) rated to 125 psi and plumb it in....

Your biggest concern when getting a new tank will be number of ports. There are countless variations of tank shapes, sizes and ports. I would take some pictures and measurements of your current tank and see if you can find an exact replacement.

This will make replacing it much easier than fabricating mounts and trying to reconfigure how the air lines connect to the tank.

I put in a screw and used some J B Weld. It is currently holding, and the bags filled up. Though I dont trust it as it rusted from the inside out so I am sure the whole bottom of the tank inside is rusted. It looks like a 3gal tank, I forgot the name on the control panel. From what I can tell it is just has 3 lines. One in and two out. I will try to crawl under and get a pic.

Thanks for all the replies, any help is much appreciated.
