P-7100 Upgraded Pump Springs





These springs are made in the USA out of the best wire available, triple shot peened for low load loss, and have a low mass and high natural frequency. When doing a performance pump cam in your P-7100, you will need to use these pump springs to aid in keeping the roller in contact with the cam at higher rpm. We also recommend increasing fuel pressure in accordance with what your pump builder dictates.

All of our pump springs are for off-road use only. Buyer accepts all liability for their use. P-pumps in performance applications can occasionally stick the rack, which allows the pump to keep fueling until there is a loss of air via an air-shutoff, until the mechanical limits of the motor are reached, or you run out of road.  Installation needs to be handled by an experienced pump builder with the proper tools and test equipment.
