Upper Housing Assembly (3/8 to 6AN)

Convert your pump to work with 3/8 fittings and enjoy convenient expansion possibilities plus superior intake flow capacity. This part fits water/meth pumps from all vendors using Aquatec pumps with seven screw attachment points. Pressure adjustments will be required using a 1/16" allen key. Do that with our famous Tuner's Pressure Gauge.

Once converted to a 3/8" threaded top, USRT's high-performance plumbing solutions may be installed. See
