That's a fairly uncommon engine, Chops. The 160 is the one that seems to be standard, but the 180 is the one everybody used to keep watch for. You'll be amazed at the torque it produces.
I'd be surprised if there wasn't a provision someplace into the crankcase for a line to the pulse pump, but if there isn't, you can make one like you plan to.
Good luck!
