Square root old vs new fuel pressure? what?

Installing a walbro pump with no other modifications to the fuel delivery system will not increase the fuel pressure. At a celing of say 60psi, a walbro can still maintain 255lph, but that doesn't mean it increases the fuel pressure to a figure over that which is set by the stock regulator. at all.

OP- I did read your original post. I know you bought it for your SR. There is no reason to. You should just find a stock SR MAF instead of using an AFC to gimp a Z32 MAF install. Get rid of your AFC, or else your SR will run like shit too.
