Hello, Can you help by measuring the overall height of the 3 HW oil pump plus the length of the 2 plungers. I am trying to re-build a 3hw engine and am lacking the correct oil pump ,so have a pre-unit one with an alloy body in good condition,but its too tall to operate properly, hence the request. The size from the machined face with the oil port holes to th top would be a great help.
