Kinsler diaphragm high speed bypass valve with restrictor jet provision, neoprene diaphragm, gasoline and methanol, hard-anodized aluminum. The advantage of this valve over the “jet can” type used in the past is that it has less internal friction on it’s moving parts, and it has a much larger area for the pressure to act on for regulation, resulting in a valve that opens at the same RPM every time. Easily adjusted using a blade screwdriver and a 7/16″ wrench.
Recommended to run between 20psi – 90psi.
