Pump will not go lower than 26psi. Thats the lowest it can be internally regulated. I really think it is too much pump and causing spikes at the guage that I can't see(gauge under hood)while car is under a load. As fuel demand goes up I think the internal bypass is causing it to just push by the regulator. I can take the adjustment screw on either regulator all the way out, in my hand, and it still has the same issues. I also just discovered that there is NO fuel filter in this system anywhere
