    can I ask why you are doing this?

    how do you plan on regulating the fuel pressure?

    if the fuel pressure is higher doesn't this mean you will be richening up the mixture?

    the oem fuel pump bolts to the top of the tank - you can see all the nuts that hold it in place if you look at the top of the gas tank - undo those nuts and the fuel pump will come right out

    if you want send me an e-mail and I'll send you some pics

    For few reason :

    i'm going to premix , i thing oil+fuel mixture is more "thick" than fuel only , so perhaps the stock fuel pump need to do more to push it for the injector .

    I use the "255" on many aftermarket turbocharged car i make , the 255 is very reliable compared to stock and you can count on his performance in any situation .

    it's cheaper to replace than stock .

    i have see here the #3 cylinder broken perhaps due to a lacks of fuel in the #3 perhaps due to a lack of pressure in the fuel rail .
    better fuel pump is perhaps the solution .

    i need the picture of the electrical pump in the plastic encloset .
    you can post here for everyone , i will post my work too .

    do you have an aftermarket fuel controller?
    Do you have any mods?

    yes
    my ski is in building : 3 key, riva efi , D plate , reed stuffer & spacer ,bb 85 or 86mm piston (not buy yet ) , freew flow , r&d plenum filter , head cut , r&d valve & weave eater , cylinder ported , r&d trim tab , r&d plate , r&d aquavein .

    i'm friendly with piggy back like the riva efi , i use smt6 , apexi , aem etc... piggy back on car .
    you can add more fuel by tricking the injector pulse duration , but if you have fuel pressure drop issue , it can't solve it .

    10-4, I do believe WFO has some tips in this category.

    There are some other EFI gurus on the forum too...

    Fuel system

    I was wondering how much power will the stock fuel system support? I think a 255 is overkill, the fuel pressure regulator may not be able to return all the extra fuel. I have not even seen a picture of the fpr, I assume it is a return type? Larger guage wire to the pump may be all thats required, a pressure guage will answer this question.
    FYI a 255 with 10awg wire easlly supplies my Syclone with fuel and it makes about 465hp on pump gas & meth/h2o injection.
    FYI2 a 190 with stock wire supplies my GSX Sypder with fuel for about 330hp, it overuns the stock FPR it idle.

    I love turbos!

    i have no issue of overun with this pump .
    and no problem about the pressure regulation .
    on my car i have fpr and set them to 3bar , they do their job .
    for me car injector or pwc injector is the same .
    just give me some pict because i can't remove mine for the moment ,and i will see what i can do or not.
