i have a 89 mustang, 306 with gt40 heads, dome top pistons, eagle crank , small cam not sure of ratio, 2and half inch exhaust with h pipe. The guy i bought the car from had the motor rebuilt. When the fuel pump went out he installed one on the frame instead of replacing the one in the tank. im not sure of the size. What i want to do is drop the tank and fix it back like it is supose to be cause the external one is so loud. If i do this will the stock fuel pump be enough, or do i need a bigger one? thanks for the help.

bigger is better. But you dont need it yet. Do you have the whole shabang? H/C/I?

grab a 190lph fuel pump, itll be enough for most mods you want to do down the road

sorry this newbie dont know what h/c/i is. What size is the stock fuel pump? lph

Crazyfast50stang

head/cam/intake manifold stock fuel i think is 155??? Im not sure but its not great

i think stock is 95 lph, like posted above a 190 lph will be plenty for your set up

Yup go with a 190, and actually the pumps are fairly easy to replace and not a pain in the A$$ like other cars. Good luck

i'd uprgrade it right now instead of puttin the stock pump back in, but the stock pump is something like a 87 lph i think, real ****ty.

do they make a 190 that goes back in the tank or are they external only?

razarr69

they make up to 255 lph intank pumps that im aware of, there coul be bigger ones out there.
