Use caution when installing Raptor 100

Recommended Posts

Had an pureflow VP- 100 Raptor start running erratic with fuel leaking from elect motor and motor running in spurts. Got shipped a warranty replacement. Installed it. Fuel pressure was 5 psi. Adjusted the relief up to 20. After few seconds pressure dropped back to 15. Let it run there for 10 minutes. Wait and see what happens. Then I cranked it up to 18. I thought the adj. screw was pretty deep compared to the last one. Should have trusted my instincts. Next morning on the way to town, I hear a pop. Blew up my oil filled guage. Installed a 0-100 test guage and found it pushing 65 PSI. Cranked it back to 18psi. Going to run the 100psi guage for a while and see if this thing is going to stay adjusted. ( 6 hrs of running so far) I think there was debries under the regulating ball and seat.
