oil pumps

[Davy Sprocket]

hi another very interesting question ?
doing few different projects are the oil pumps all the same or do they have different flow rates/markings
i cant see anything and they may have got mixed up after a bottle of wine-- the flow rate of which does remain constant--- cheers dave

I'd not seen Darth's page of test results before Dale, that's great!

So in effect, there are only two different pumping gear sets.. S Series and H Series..
Then any model differences are simply down to the cam plate diameter.
That must be why some cam plates are engraved with the model.

That's bound to help many people who have odd Pumps hanging around.
