Feuling Oil Pump PSI Tester For M-Eight - 9006

Bench test the Feuling M-Eight oil pumps, cycle the pressure relief valve, testing operation and assuring the valve moves freely, seats and seals each time, any leakage at the relief valve will reduce oil pressure
This tool allows the engine builder to know what psi the relief valve opens; the spring tension can be adjusted to achieve the desired pop-off psi
Tool includes: air regulator, 0 - 100 psi pressure gauge, plugs for water and oil cooled oil pumps, gasket and needed hardware
Feuling recommends the oil pump relief valve be seated and sealed from 0-30 psi with full pop-off at 50-60 psi
Proper relief valve seal will insure good hot idle oil psi and reduce oiling system cavitation and related pressure issues
Made in the U.S.A.
NOTE: Fits Feuling oil pumps only; does not fit factory HD oil pumps
