Air bag losing air

[phelpo]

Been traveling back from Ohio (dealer location) pumped
bags up to 60 lbs. First day driving was bad, very heavy winds
blowing me all over the road and the trucks!! Air in fronts 75 lbs,
rear 80 lbs. Well the next day I'm checking the air in the bags,
50 in one and about 25 in the other....darnnnnnn...pumped
them back to 60 lbs and will see where they are in the am.

Looks like a soaping job to find the leaks. Anybody else
have this issue?

Yes, had leaking bags on front end of E-450. Firestone somewhere publishes a acceptable loss rate. Yours was excessive. Easiest "soap" I know of is a bottle of windex- spray the disconnect fittings and fill fittings for obvious leaks.

Had similar problem with my air lift bags on my truck. Turner out to be malfunctioning manifold. And they no longer make it.

Can I get more info on what model/brand what every I can get on the front air bags please.. I only have them in the back but want to see what it takes to add them in the front..

O and by the way one of mind in the back leaks as well..they are boxed up in the compartment pretty good and it's just a slow leak so I just check, adjust before any trip..

Firestone front air suspension air lifts

Are there air bags on the front suspension also?. I was under the impression only on the rear. Have sunseeker 3010

[phelpo]

Rear only

I installed the coil spring bags aftermarket, quite easy.

One bag stayed at 60lbs the other went done to 20 lbs
I checked the values and no air bubbles

We have a 2014' Sunseeker 3010DS same problem our rear right side bags had leak, we put 70lbs of air so the rear jacks would clear most driveways and also turns at some intersections and after every trip the next day, rear right side airbag down to 10lbs if that? the dealer replace the air line and it holds the air all the time now, at first they said its ok checked all the air lines and bags but still leaks,so after calling them with same problem they changed the air line and no more leaks

I'M going to see a repair shop in a couple weeks to get it
fixed.

The valve on one of mine leaks after I check the pressure. I have to press the guage on it a few times for it to stop.

Plastic air lines?

Spray them down with soapy water look for pin holes.

[phelpo]

Good idea if you could get to it. Covered with plastic covering And foam insulation

[phelpo]

update, was referred to campers inn in Jacksonville fl, they ended up replacing both air lines since they could not find the air leaks, got my fingers crossed and prayers lifted up

I would suspect the schrader valve before anything else. I've soaped the valve before and often get a slight bubbling. The caps aren't going to hold 80 psi back.

On the tubing, Firestone manual points out in the install of the tubing to make the cut as square as possible and insert the tubing as far as possible into the fittings.
