Since this carb didn't have a fuel pump built on it like the first one I tried, I robbed one from my lawnmower for testing purposes. It worked so well I decided to keep it on there and buy another for the mower.
I've never heard of or seen a pump design like this until starting this project and am fascinated by how simple they are. If you are not familiar with these, they are pulse pumps and use +/- pressure from the motor to actuate a diaphragm which moves the fuel from the tank and at a few PSI.
Got it mounted and I'm happy with the results, almost looks like it was made to be there
