if you use a 190 or 255 fuel pump (regardless of engine upgrades) as long as you use an adjustable fuel regulator.

 

i could be wrong here but pressure doesn't have anything to do with actual amount of fuel flowing.

 

No and you don't need an afpr either. The unused fuel will just be returned to the tank.

 

ok thanks, was just curious cause i have never run juice before and want to make sure everything is right.

 

if your squirting 100 jets on a mostly stock stang the stock pump and injectors is fine, you should get a new pump though simply cuz the one you have is really old, so might as well bump to a 190.

a 190 + 24# injectors will support 400 hp no probs

 

Didn't say anything about running juice in your opening post[&:]

 

go with a 255, u cant out grow it that easily and its not that much more money. Just another thing u would have to change later if you went with the 190

 

an AFPR is NOT a replacement for getting a fuel pump. the fuel pump is rated on how much fuel it can push out in an hour. the fuel pressure regulator adjusts how much fuel actually goes in. so you arent going to make a 190lph pump as much fuel as a 255.

 

sorry, but you had answered the question i needed....but i'll make sure to add all info in the future.
thanks

get the 255lph
