how about a pump off an OS 155 (click my first link), but most likely it runs off crank case pressure so you will have to tap the back side of it for a hose barb, and make a mount for it. if you want it check into it well so you will know if you can put a hose barb on it. and you will have to tap the engines back plate..
also, with a pump on such a large engine will you need a regulator ? if you do some of the OS 91 and 105 Heli engines have regulators, I bought some for my Saito engines I will mount inverted, the older os 91 regulator is like $70 or $80, and the newer one is nicer but cost $115

there is one more OS regulator, it's the same as the older one in my last link, but it mounts like the newer regulater..
