Anyone have any ideas on what the heck is going on with this, help please. My truck loses air over night, and well i'm driving after a couple hours i have to hit up on the front switch. Slowly but surely the air seeps outta some where. I have four valves and front and back switches. The truck was this way when i bought it so i replaced all valves, air lines, and just installed brand new front bags. I'm outta of ideas on how to solve this problem. I've checked everything and to my knowledge there's no leaks, obviously something is going on. Is there such thing as a faulty front switch. Or what could it be something in the tank maybe. The back holds air perfectly fine. and installed exactly the same as the front. Any input would be appreciated! Also if i let a little air outta the front bags let the back end down and fill the rear bags the front bags slowly creep to the ground. What's up with that. The leak seems to orginate somewhere in the 8-10 hour range of sitting, for the first 5 6 hours it's fine...

There is a leaky fitting or airline SOMEWHERE on the truck.



Grab some soapy water in a spray bottle and spray ALL the fittings with it. If you see little bubble theres your leak.

CHECK YOUR COMPRESSOR SPRAY SOME SOAPY WATER ON IT SEE IF IT IS HOLDING THERE I HAVE SEEN A TONN OF THE SH##Y AIM COMP LEAK AROUND THE HEAD AND YOUR VALVES OPERATE OFF OF PRESSURE SO IF YOU ARE LOOSING AIR AT THE TANK THEY WILL LEAK DOWN

Thanx i'll giver a once around again!

what kind of air guages do you have?If they are mechanical thats a big leak area.

whats the temperature over night i know mine would lose pressure if it was cold out

r u runnin check valves off the tank. sometimes when theres a leak at the compressor, it helps to have check valves so no air can pass back through the lines, which doesnt allow air to travel out. also, like MO said, temp has a lot to do as well. air expands and contracts at diff temps, which may cause this as well. like they said, a spraybottle with soapy water should help u find ur leak!

might wanna check your dump valves and make sure they're clean. Might have a little piece of trash in there thats not letting them seal all the way.

if you arent running check valves off the tank and have a leak in the tank the bag pressure will equalize with the tank and since your front bags take more pressure to pick up they will leak down first. I can pretty much proise you there is a leak in the system somewhere, it could just be that you have a pinhole in a line also, I've had that happen a couple times.

My ranger did the same thing. My compressor was a viar 450 so it had a check valve already in it. So i bought check valves and put them on the front valves and it solved the problem. I recommend check valves whether your having problems with air leaking out of not.
