h/c/i do i need a better fuel pump

[feifong]

my car just had a h/c/i swap when i let go of the accelerator in first gear seems like it wants to stall out It will sputter like it is in high gear going slow could this be my mechanical fuel pump cant keep up with the new boltons? Should i switch to an electric fuel pump? Wich one do i buy?

What size fuel pump do you have now, what kind of power are you making, and is this carb'd I'm assuming?

It is def time to upgrade your fuel pump and fuel injectors. These could be what are causing this problem but I dont know enough to be sure.

He said it was carbed so there are no fuel injectors. But yes I would go with a different fuel pump. When ever you go with a combo like H/C/I then you are making a lot more power then before and you are pulling in a lot more air then before as well. So you need to pull in more fuel as well.
