Re: whats the diference between the gss340 and the gss307 ok, i guess i will answer my own question but i have a new one also, here http://www.gnttype.org/techarea/fuel...albroflow.html i found some flow graphs of various pumps, it shows the 340 and the 307 about the same at 60psi, it also shows them at only 50gph. thats not going to get it done, on another page it shows the flow at 57gph at 13.5v. lets say i go with the 57gph, i don't think that is going to get it done.
right now i have 41lb@58psi injectors, that works out to be 55gal/hr. and i maxing those injectors out.
so my new question is, is there a single intake pump that i can toss in there that will flow more like 80gph?

Re: whats the diference between the gss340 and the gss307 it is always a good idea to throw a relay in the stock wiring and bring a hot wire from the battery to run your pump at 14 volts instead of the stock voltage which is regulated around 12
i have measured mine to be 14.11 volts to each of my pumps.
if you paid for a 340 and got a 307 i think its worth your time to send it back and get what you paid for.
what kind of power you looking for? a single gss340 will support 550rw FI
