My Carter electric fuel pump took a crap on me and has forced me to look at replacement options. When I picked up the 70, the owner said the motor needed 8 psi of fuel pressure. That said, the single carter was pumping out 5.5-6psi according to my autometer gauge and the motor seemed to be running just fine. As all of us know, those electric pumps are noisy as can be, even when installed with rubber insulators. I see that some of the mechanical pumps on the market put out 8 psi max now. If I can avoid the noise and hassle of the electric I would like to, but I also don't want to starve the motor. What are the benefits of an electric vs a mechanical fuel pump?
I haven't found any good explanation for how the mechanical works in terms of psi it puts out. I would imagine they run 5-6 psi at idle with 8 psi under full load? Has anyone had good luck running those higher pressure mechanical fuel pumps with a more built motor? Anyone know of any mechanical pumps that put out more than 8 psi?
Thanks for the edumication guys!
