Can anyone advise how efficient the oil pump needs to be on the Jerry Howells V2 twin engine. The pump I have built does self prime (just) and does pump oil in a steady flow, more of a trickle than a flow and pumps at the same rate irrespective of shaft speed. I'm confident I have built as designed and can't see why it does not produce any better pressure. Any assistance would be greatly appreciated.

Many thanks,

Max
