Order of air tank draining?

not that I know of.....but I always hit the drivers side first..cause that's the way I come out of truck.......

 

wet tank first, then the dry then the service.

now, in most instances, the wet tank is either the lowest mounted tank or, the tank furthest away from the air compressor.. some trucks that i have seen, actually do have labels on the tanks. but in time, those labels lose their readability from the weather, and washings.

so, if you have one tank on the passenger side, and your compressor is on the driver's side, well that'll be your wet tank.

reason to drain wet tank first, is to prevent all that crap from getting into the other tanks, should you not do this correctly, thusly allowing crap and water into the dry/ service tanks, and pushing all that crap through the system.

 

Hmm..on the ProStar, both air tanks are mounted right next to each other on the driver's side below the fuel tank. I'm almost certain the wet tank is the right one as that's the one that had some water spray out when I drained them.

 

Shouldn't be any certain order. Really on the new trucks they usually stay pretty dry. Sometimes it depends where you are running too. I have found when you come out of the desert and get towards Oklahoma that you get a little more moisture build up. Same with running in the southeast states where the air is more humid. Try to just remember to include it in your post trip at the end of the day. Personally I found I could do it once a week and be just fine. Like I said though it depends what truck you are driving and where you are driving it. Good luck.
