I just bought a Marzocchi pump on ebay cheap, it's 750 milliliter/minute @ 1,500 rpm, will go to 7,000 rpm. Will give more info if there is any interest.
Most of the hobby pumps appear to be 300-350 milliliter's/minute.
The furnace oil pump in a previous post, Well I had to find a new conversion app for my phone, number's are off!
