Anyone that was reading this and asking the same question, static pressure for a single turbo RX7 seems to be 50psi.

 

I hooked up my new FPR this weekend, but something is wrong with the setup because it reads ~22psi no matter how much the adjustment screw is tightened.



I think it's because of the stock FPR, but for ***** and giggles I'll lay out how it's setup:



Fuel out of the secondary rail --> FPR inlet --> FPR outlet --> fuel return line to tank.



So I think this means I need a new secondary rail in order to work with this setup. In order to make this more complicated, I've already modified my 1680s to fit in the stock secondary rail...

 

Hey dude it is a rising rate regulator not just a fuel pressure reg ? and it doesnt matter if it sounds like your fuel pump is running its what comes out of the pump - google what pump you have and see how much pressure it should be at straight from the pump like someone already suggested put the lines in a bucket. also are you running omp still or are you doing it with premix straight into the tank?
