Ok fellas, fer us dumb ol' country boys that speak psi. instead of nm. What kind of pressure are you talking about? If I understand correctly the pump you're working with puts out 43gph at 45psi free flow. I gather that' not enough. Summit sells a pump that is 43gph at 85 psi free flow, part # sum-g3138. It's also cheaper, $81.95. I've had good luck with Summit's stuff as far a quality. It looks like a twin brother measures 1.87 x7.25. Probably comes out of the same factory. This with a bypass regulator and a return line to the tank to keep the fuel and pump cool? Am I out of line?
