Lift pump with electric boost pump
Just wondering if anyone has added an electric fuel pump in line with their lift pump and if they noticed a differance.also placement and type would be helpful.

Infidel pretty much summed it up.....
I have seen many very high powered 12v's perform flawlessly with the stock LP.....I don't know what their limitations are but I have personally seen 600 hp with a stock LP and have heard of even more than that here on a stocker....my 12v was in the 450 hp range on the stock very high mileage LP with zero problems. I think this is definitely a classic case of "if it ain't broke, don't fix it". Don't expect any type of positive gain from adding some other form of inline pump to the stock 12v LP.
