yes this is my first motorhome i'v had campers its a ford E350 and its not a full air ride suspension its just at the rear axel i have cut the line and replaced with new parts and i belive that is where the leak is.
i havent had time to check it with soap/water i plan on doing that later today

Good for you, that is the correct way to fix the system. A lot of us were under the impression, that it was a DP with air brakes and suspension. Maybe including a description of your MH in your profile would help us help others. Thanks for getting back with the fix.

Do you have a gas engined chassis? What you're describing seems more like that used for supplemental air springs used to add weight capacity to conventional leaf or coil springs, not the full-on air suspension systems used on diesel powered motorhomes. If that's the case, try using soapy water to find where the leak is coming from. You may be able to disconnect the hose at the air valve, cut an inch off and reconnect it if the hose itself is leaking at that point.

The OP is a newbe here, and is probably not very up to speed on his MH, that's why he asked the question about tire sealant in the air system.

Give him time to breath. If we don't run him off, he will learn.

How bad is the leak??

Be helpful to know what chassis he has:h

Is it a pin hole leak? There are some, uh... techniques, to plug a pin hole leak in an air line. You might try looking for those on a trucking forum. These might get you off the road, for example, to a repair station.

Fix-a-flat only works in a tire after you inject it and you drive to circulate it around in the tire until it finds the leak. Circulating the sealant is not possible to do in an air suspension.

Thanks to all for the advisei am sure the leak is at the inflated valve and the plastic hose

"Inflated Valve", may I ask, what in the world is that? And, there's a few miles of "plastic hose" under our rigs and, there's different colors for different applications and purposes. At this point, it seems that you're not really sure just where the EXACT point of an air leak is yet. So, to "blindly" apply a internal sealer for a flat tire is, as most have already stated, and most likely will be, CATASTROPHIC to the rest of the air system.

So, what should be done, even if you're not all that familiar with the air system and all its components is, get spray bottle with some dish soap, (small amount) and water and create a solution that can be sprayed on each and every fitting, component, air line, connection, valve, air tank etc. You're obviously looking for any bubbles emanating from anything. Then, when you find that leak, and it can take a long time to find a leak since there's miles of tubing and, lots and lots of valves, fittings and more, then you do what's needed to repair it.

But, if you're not familiar with air systems and, all that's involved, well then either get someone who is familiar to help you or, take the coach into an appropriate repair center for your issue. Goofing around with an air system that has even 1/2 of the standard working pressure, can cause some pretty substantial injury if you're not sure of what you're doing and un-do and airline or fitting.
