Fuel pressure regulator

[Celica RZ]

What's the logic on this? Why do you want higher fuel pressure than stock? Do we have one? cause if I'm not mistaken with the return less systems fuel pressure is always constant.

I'm not sure if I'm making any sense, feel free to flame my ignorance :silly

Ha Ha fuel/flames....

Come on you should know by now it does not have to work to be a "must have" mod

The easiest way to richen the misxture is to increase the fuel pressure.

More pressure means more fuel delivered during the injectors "open" cycle.

It's a very affordable way to richen the mix (rather than bigger injectors).

I still have no clue how the Celica regulates the pressure, possibly a bypass in the pump? If so, we could bump the pressure by changing this bypass (spring tension probably).
