Fuel pump upgrade - better?

[normality78]

Well in a meet up today, i've heard a guy complaining to his mech saying his car was slightly heavy on FC. heard his mech suggested to him to upgrade his fuel pump and install an Adjustable Fuel Regulator thn get SAFC to do some tuning by cutting some fuel supply.

he said by doing so, it can improve his Fc marginally and better responsive. Does any of u heard about such thing before? The mech is driving Ae101 supercharged himself. He claimed full tank, he can travel 210 miles with 81 mph speed, and reached destination with at least half tank left . Well to me definietly is good FC.

He said have to get Power Enterpise fuel pump, 210cc thn adjustable fuel regulator and SAFC.

What do u guys think about it? make sense or simply bull****?

In here, i would also like to know, Is there any different on different brand fuel pump like Power Enterprise, Walbro? how about those 2JZ, RX7 fuel pump to be use?

Firstly I am going to assume you are talking about a corolla and if you are also talking about a current model corolla then the following will apply...

The walbro GSS342 fits in the STD pump housing with a little modification to the retaining clip, it flows 255ltrs per hour. If you intend on upgrading your fuel pump you may want to consider switching to a return style fuel system.... which means you will need to run a return line to your tank, replace or modify your current fuel rail to accomodate a return line aswell as a FPR.....

But if all you are worried about is fuel consumption them all you really need to do is install an E-manage or some other piggyback ecu that will control youe A/F ratios..... the STD fuel pump is more than adaquate for a modded NA or even lightly boosted 1ZZ or 2ZZ rolla....

Of course if you have a different model then all that really applies out of what i have just typed is
