Dual fed P7100 pump
 

anyone ever heard of doing this? i heard there is a allen head you can take out on the front of the pump and put a fuel fitting and run another lift pump, to make it dual fed, kind of like a common rail? put some input please

Yeah you can dual feed a 7100, its not going to be any more similar to a common rail then before, and you have a couple options on the second feed port, you can use the allen head screw out and feed it, or feed the stock return and have the allen screw as a return. Either way, you better be pushing SERIOUS fuel before starting to think about the need to dual feed...
