    Default How much fuel pressure?

    My KP61 fuel tank is in horrible, rusty shape. I'm replacing it with an inside the car, outside venting, aftermarket, aluminum tank and want to also replace the lines from the tank to the 4-age stock fuel rail and the return back to the tank with 5/16" braided line.(it's currently a mix of 5/16" and 1/4"Fuel injection hose)
    I have a stock, but not to the car 4-age.
    How much fuel pressure does say a stock AE86 have/need?
    I don't want to order an aftermarket pump with too much or too little and if I do, I'll need to know how much to dial into an aftermarket fuel regulator.
    This is NOT a race car. But it is starting to look like one. A fact that is fine with me.
    Thank you.

    40psi is about right for a stock 4A-GE powered Corolla. A standard replacement pump is fine, no need for a massive Walbro/Bosch etc.

    Thank you.
    Other than the Starlet having the 1/4" steel lines for its tiny carburetor. Replacing them with 5/16" is all I will do then. The fuel injection pump I already have seems adequate.
