In looking at fuel pumps, how does one compare lbs. per hour and gal. per hour. I am trying to figure out the low pressure pump to the sump and the high pressure pump to the injectors. The high pressure ones are rated in lbs. per hour. ex. "Flows over 450 lbs. per hour @12 volts and 45 psi". The low pressure pumps are,"maximum pressure in psi" from 2.5 to 7.5 typically. with a flow of 15 to 35 gals./hr. at 1 to 2 psi. with max gals/hr of 28to 45.(small pumps). I assume that is unrestricted flow. I am currently looking at the Holley blue pump with max flow of 110gph for the low pressure side, and the Aeromotive for the high pressure side. Is the low side overkill and a waste of money?
It is a little confusing to me. I don't want the high pressure pump ever to starve, although I don't think it will with the return line from the injectors to the sump, and an overflow back to the tank. I am just trying to be careful. Any help would be appreciated.
