hey man.... I removed stock air compressor and ran lines into a "t" and the fill line was ran into the stock inflator nozzle in the cargo area. I checked for leaks and after finding none i bought a $25 5 gallon tank and a viair compressor and mounted the compressor in stock location. The tank is inside cargo area. Ran a switch with gauge up to the radio area. Retained ride, fully adjustable when i want, faster than adjustments than stock, and i love that after i installed belltech 2" drop on front, i was able to level the truck! Food for thought!

You have a leak, probably the air bags. The compressor will not run when the iginition is off, hense the "sag".

This is what I would do, there are choices http://www.strutmasters.com/gmc-envo...parts-s/95.htm

I'm not affiliated with strutmasters but I like their products.
