I am going to be running DSM 450's w/ the AFC hack. I have an aftermarket fuel pump (Walbro 255) but I dont have the $$$ to get it installed. My fuel tank needs to be dropped to install it, and I dont feel confortable doing something like that myself. Will my OEM pump be able to provide enough fuel for the injectors, or should I stick with just an FMU till I have the $$$ to have the pump installed?

Yes you can.


I guess it really depends on what kind of fuel pressure you plan on running, but you're probably going to run around stock.

stock pump will prvide more than enough for the 450's. with stock everything else, you will run too rich.. that is why you need a way to control the injectors by correcting fuel in the negative direction.

I want to run rich. Not too rich, but richer than stock. Nothing worse than leaning out a turbo setup. I have the AFC to control the a/f mixture, and I am not gonna install the DSM's without the AFC.

yeah, just use the afc, dsm injectors, and resistors and leave everything else stock

yeah, without a way to control them, you will run so rich the car will bog.

Now that you have brought it up, resistors is another thing. I got a resistor box from Boostaholic, but when I called InlinePro to see about installing my whole fuel setup, I was told that I didnt need that resistor box with my car. Is this right? I thought that I did.
