David Bathe,

you can download Perry pump instructions here http://www.perrypumps.com/instructions.htm.

Instead of using the pressure fitting that comes with the Perry VP30 pump I use the O.S. 140EFI pressure fitting installed in the upper left crankcase cover bolt hole of the O.S 1.60FX and find that the pressure line diameter is not critical. Maybe there is more pumping action available through that fitting. I'm running three OS 160's in that configuration.

The picture shows the pump mounted snug with the engine and oriented as suggested in the instructions.
