Hey guys, as it well known Ralliart's fuel pressure regulator is constant rate inside the tank type. This limits our options for regulating the pressure. I was thinking, the pump and regulator are Denso brand, and I'm guessing a bunch of cars use that brand and maybe there is one that fits and has more than ralliart's stock 43psi?

 

proly just easyer to switch to the return fuel system form and evo ro and 04 lancer then add the FPR. this also makes tuning much easyer and you woudnt be set at one pressure also u have to do the same amount of work to get the " so called new FPS in there any ways to why not.

 

Just weld the stock regulator put it back in play with your fuel pressure and problem solve....
