Mine's empty too but it because of other things. My list of upgrades for the Cummins is still TWINS and a real nice clutch but the A/C is bummed and the fan is screwed up and the E-brake doesn't work anymore. Oh did I mention the rust on the drivers door and the need for bumpers and a new long box? Oh well, it's a truck that is paid for and owes me nothing. It isn't a daily driver anymore so it will be ok for a while in the state that it is.

Like I said before it's a slippery slope. -

13 psi is not a terrible pressure by any means. However, if you would like to get a couple more pounds out of your AirDog, you can install a 17 psi spring to replace the 15 psi that is sent in the pump from the factory. This should give you a couple pounds more pressure at your VP pump. This spring is available from your local AirDog dealer or directly from us, and is easy to install. Feel free to give me a call if you have any other questions.
