Aeromotive Ultra Low Pressure Regulator 13222 - Those who love and run the classic Weber, Mikuni, Dellorto, Solex and other side-draft style carburetors have been asking Aeromotive for a high quality, high flow regulator suitable for these low pressure applications for years. Following a late night discussions at SEMA 2014, Aeromotive knew it was time to dedicate a serious engineering effort in this direction, which has now culminated in the new P/N 13222 Low Pressure Regulator. With an adjustable range between 1.5-5 PSI, and a soft-seat style valve designed to eliminate pressure creep, racers and enthusiasts can now take advantage of high flow fuel pumps with 15-20 PSI of line pressure, without fear of flooding. The new P/N 13222 Low Pressure Regulator features a completely unique body, designed to support high flow at very low pressure. Intended for multiple, smaller carburetors, the body features one ORB-06 inlet port and two (2) ORB-06 outlet ports, along with a dedicated, 1/8” NPT gauge port. Constructed of billet, CNC machined 6061 T6 aluminum and finished in bright-dip, clear-coat anodizing, it has a clean, subtle look that blends nicely into the engine bay.
