Hi guys. I have a 1971 Bombardier snowcat that has a 251 chrysler flathead 6 cyl. It's near impossible to find parts for because all the auto stores want to know what the engine is in. When I tell them, they look at me like I have 3 heads. It's a very basic mechanical fuel pump. It does not have a glass bowl on the bottom. Any ideas where to buy one? thanks! Here's a pic of the engine. The top of the fuel pump is barely visible just under the manifold.
