Get the most fuel flow possible from your stock CP3 pump with this “high flow” PPE CP3 Pump Inlet Fitting. The key is the larger inner diameter of the PPE fitting, which allows fuel to flow 70% more efficiently than with the restrictive stock unit. With a greater volume of fuel available to it, the CP3 injection pump will be able to perform at its optimum capability.
