Fuel pump
Ok got a question for the fuel folks out there. If I'm runing a 40gph mech pump that puts out 7.5-9psi reged @ 6.5 psi. Would putting a e-pump 35gph 4-7psi at the tank and still having the mech pump. Hurt, Help, or do nothing. Mech pump has a return and reg is deadheaded @ the carb 3/8 main line. Think I might be dropping pressure under WOT in 1/4 run.

Re: Fuel pump
It would help if you had a problem with vapour lock but wouldn't do much for performance.
