Rube.....Having no experience with pushers, on my first one I put the tank in with the stopper to the rear. Boy it fit great and looked good too. BUT (notice the caps) when we held up the nose to check the needle setting the engine quit, tried it three times and quit three times......it seems the clunk has to be at the rear of the plane with the nose up to get any fuel, odd huh! This time, on the EZE I put the tank in with the stopper fwd and it works great. Cliif good luck
