how big of a fuel pump do i need?
i have a 1988 5.0 engine in my 1990 body mustang. I just did the swap and i am haveing a problem with the engine running really lean and at full throttle its ass is falling out. i think it is because i have the stock GT pump in there with stock 19lbs injectors. i have a bunch of upgrades including bbk intake, edelbrock upper and lower intakes with phenolic intake spacer, bbk headers, bbk underdrive pulleys, bbk h-pipe, flowmasters, you know just all the bolt ons. now my question is with all those add ons how big does my fuel pumpo have to be? 155lph or 190 lph? also how many pumps does my car have? 1 in the tank and one in-line or just onbe?

190 would be enough for you. there is really no such thing as too big, cause your lines and fpr only allow a certain amount through anyhow
