Dean we used to run the holley pumps on our I70 racer we had a problem with the spring loaded bypass plungers sticking man we chased this problem for awhile.I think the Aeromotive are a higher quality pump from what all the racers around here say they wont run the Holley stuff anymore .We still run a standard Holley electric pump on the street car but it doesnt sit much any moisture in the fuel while sitting for extended time seemed agervate my pumps,hope this helps...WB3
