502 Mag Mpi Fuel Pump
 

Hey does anyone know what the fuel pump for a 502 mag mpi flows...GPH...going from 502 mag to 555 with 850 carb ..i really want to use the merc cool fuel for this build I personally dont see this being a problem but i would really like if someone had actuall flow numbers for this pump ..any help would be appreciated

If I am not mistaken, it will be too much pressure.

Im guessing he is talking about the mechanical pump off the gen V mag mpi that feed the VST.

I looked and looked, never found a hard number for the flow of either pump.

However, CP Perf sells one advertised as moving 130gph. $140, not bad.

I am talking about the electric pump on an mpi pressure doesn't bother me I will be regulating ...and I'll tell u what the merc cool fuel is a nice set up ... no worries for vapor lock and no strain on the pump since it returns to filter housing very nice

I'd be willing to bet it has to flow 120 or better and that's plenty for this project
