that looks a bit like a coffee grinder. I had seen a small drawing on the Yanmar site somewhere but can't find it again. My dealer listed one as included with my new 3YM30 but sent a monstrous orange thing with a handle big enough to turn the engine over! I'm guessing it's the wrong part... Trouble is the boys in the Parts Dept are in the dark on what is the correct part. A photo or part # would be helpful. I had a small brass handpump plumbed into my oilpan on my old Pathfinder and it worked slick. I don't need anything too fancy for such a small motor but I'd like to get my dealer to sort it out. Thanks for your help. Best regards, David
