    What's a diaphragm? *scratch head*
    From what I read in this thread, it seems that fuel pressure regulators benefits almost all fuel injected cars. I'm running a satria 1.6L manual tranny with just a k&n air filter. I saw the arospeed ones (see link below).

    Click on picture for details.

    I was wondering about something. Some have mentioned in-car fuel pressure meter. Is it one of the products above? Or is there another separate meter to be installed in the car?

    yup.if i'm not mistaken,the ori press is around 22-28psi.32 psi should be
    enough for ur car.too high n ur car will be sluggish due to too much fuel been
    injected into u engine.
    diaphragm is a piece of rubber found inside the fpr.it benefit ur engine by
    spraying a more even fuel so the spark plug can burn more complete.making
    a bigger explosion inside the combustion chamber thus increasing ur engine power.
    no,it's not bro.the pic that u see is the meter that attach to the fpr itself.
    to install a meter inside the cockpit,u need to buy meter like defi,apex'i or
    those taiwan meter that read fuel pressure.

    gt auto,
    oh, like that ar. erm.... well, I think I'm going to install e-manage before all else la. hehe Heard that e-manage is a good investment and can help obtain some easy bhp's too. hehe I won't be expecting much from it, though. 10% also happy already. hehehe

    I have problem with my FPR, my engine is 4G92P, with harder valvesping & P&P head modification, currently my FPR default reading is ard 50psi, im using 2nd hand arospeed FPR and im using honda civic (denso) fuel pump, are my reading reading normal or the FPR diaphragm broken or damage due to leaking or something??
    p/s: if i tighten it, it can only compress to max 52psi & if i loosen it, the indicator pressure also shown decrease less than28psi, the question is...
    1. Fuel pump problem or
    2. FPR diaphragm problem?
    3. Where can i find the Arospeed diaphragm kit?
    Thanks in advance...

    might be ur fuel pump cannot put out more pressure than 50psi.
    i think aerospeed afpr cannot changed the diaphragm. as u can see, it uses rivet instead of bolt and nut.

    that might give better voltage to ur pump.
    might be u wanna check the voltage drop at ur fuel pump while running 1st.

    rewiring dedicated cable for pump (bigger/better cable) + relay will help deliver most of ur pump performance.
