what size fuel pump 190 or 255 for a 6 psi supercharged stock 302 has stock cam and heads but not injectors or tb and supercharger sits atop the engine. full exhaust though on it

 

Go w/ the 255!!

 

would i have any engine trouble or computer trouble running that big of a pump or any trouble installing that big of a pump?

 

No, the physical size is the same. As for the volume, it will be ok.

 

well i never plan on making anywhere past 400 horses, so wouldnt a 190 be enough?

 

I run a 255 in tank and an external w/ my set up. Buy the 255. You'll be fine.

 

you can probably get away with the 190 but why push your luck. after a while youll get tired of the hp and want more and end up doing more mods and will need the bigger pump.

i run a 255 in the tank and an t-rex in line pump. it wont do anything to the ecu. any fuel that isnt used just goes right back to the tank
