hemsteadc Posted November 22, 2020 Report Share Posted November 22, 2020 (edited) 2008 Sportchassis cummins 8.3. I have 2 air tanks, and both have that needle valve thingy on them you're supposed to push now and then to expel any condensed water inside. One of them has a slow leak, and I'm not sure how to stop it. I have crawled underneath and fiddled with it, and I got the leak to become less, but I can't stop it and it allows my rear suspension bags to deflate over a few days. The next thing I may try is pushing it open and blowing air back up into it, thinking there's something like a grain of sand stuck on the lip. I hesitate to take it apart as I'm out in the sticks and I don't need any catastrophes. Anybody have any ideas? Thanks Edited November 22, 2020 by hemsteadc Quote Link to comment Share on other sites More sharing options...
Darryl&Rita Posted November 22, 2020 Report Share Posted November 22, 2020 Change it. Rubber seal is likely shot. If your rear suspension is going down, you may have another leak you don't know about.

Are they standard pipe threads? I really don't need this thing as it never has any water in it.

Ray,IN Posted November 24, 2020 Report Share Posted November 24, 2020 (edited) A pipe plug is a temporary patch, the air drain is required. As rickeleio said when the air dryer is functioning as designed very little/no water will be in the tank, If there is water in the tank there is a chance water also found its way into the air brakes, which can be a dangerous and expensive situation. For semi-tractors, if stopped by DOT, they will pull the cables to the manual air drain fitting for a test. That is how important the manual drain valve is to safety. The most important item to avoid moisture is the air dryer assembly, including its regular maintenance.

You still have an air system, that needs care and attention. If you skip over it, you'll end up paying in the future. Either when you have to replace extra parts due to rust, or when sale time comes, and the buyer catches your skipped maintenance.

Darryl&Rita Posted November 24, 2020 Report Share Posted November 24, 2020 Entirely friendly. Your air dryer maintenance has been mentioned in the past. It's your choice.

noteven Posted November 25, 2020 Report Share Posted November 25, 2020 (edited) Example on Amazon for $13. I only maintain truck air systems with parts "intended for a truck or bus" (sorry I don't know the correct backed up by documentation to prove it term) often found at the truck dealer's parts dept. or a reputable commercial vehicle aftermarket source.

Crawling under this truck every day is not something I'll ever be doing. I have never found the air dryer, and according to my mfr, there isn't one. I'll keep looking.

noteven Posted November 25, 2020 Report Share Posted November 25, 2020 If you do not have air brakes your truck may not have an air dryer. If it had one you would hear it discharging contaminants when the compressor cycles off. If there is no dryer fairly frequent pulling of the drain lanyards when you are doing your pre trip walk around with the engine running is a good habit.
