1999 Chevy Dually

CREW CAB DUALLY. ORIGINALLY BAGGED BY DREW BROTHERS. NOTHING WRONG WITH THE WORK, BUT THE AIR SYSTEM WAS SUB-PAR FOR A CREW CAB DUALLY. SO WE MOVED EVERYTHING BEHIND THE AXLE IN ONE LOCATION INSTEAD OF VALVES COMPRESSORS BEING MOUNTED EVERYWHERE THROUGHOUT THE TRUCK. UPGRADED FROM TWO 3 GALLON TANKS, TO 2 6 GALLON TANKS. AND PROBABLY TOOK 2/3 OF THE FITTINGS OUT OF THE SET UP. THAT ALONE SOLVED MANY OF HIS AIR LEAK PROBLEMS.
