fuel pump question

I need to change my fuel pump soon, and wanted to know if I can put a performance pump in now. I dont have any mods done yet but will eventually. That way I dont have to change it to a higher flowing one after the mods. Or do I have to put a stock one in until then? thanks for the help

Do a good swap now while it is out. Throw in a single walbro 255 and hotwire kit from racetronix and it will be good to 500whp or more

Re: fuel pump question

So, the higher flowing pump won't mess with the stock set-up ?

Re: fuel pump question

No because your fuel pressure is controlled by the fuel pressure regulator, not the fuel pump.

Re: fuel pump question

yeah its a nice kit because it runs direct alternator current/voltage to the pump to gain even more flow since voltage is higher. Its good if you plan on doing some mods down the road. Its not all that more expensive either. Easy to install as well.
