    Default Larger fuel pump

    If I install a larger pump like 345 Lph. will the stock in tank regulator control added fuel ?? stock pump is in the area of 235 lph. Thanks again.

    If you add anything over a 300lph pump the stock wiring will not be enough to power it. you have to put a new harness to the pump. Easiest way to modify the basket is to buy Hypotek's basket bracket. if you go look at BoostedMotorsports YouTube he has a good video of modifying the stock basket.

    however to answer your question yes the stock regulator will control the added fuel. But for how long idk and how efficiently idk. if you are planning over 300lph i would just get an aftermarket Aeromotive one and run a return with it as well.
