Ummm... . I thought the plunger, including the groove in the top, is one of the advantages.

Reb.

You need to listen to Joe D. on this one.
BrettWilliams said:Just for the record, it makes a difference at what rpm you record your fuel delivery. Some test benches don't have enough hp to turn a big pump at a rpm thats very high.
The lower you run the rpm and record fuel delivery the bigger the number can be.

That was worth repeating.
Did everyone read that? Now rush back to your pump shop of choice and ask them what rpm they tested your pump at.
When they can't answer that, ask them how many hP the pump stand motor has.
