Our John Deere 450j dozer has a manual fuel pump with a lever. I drained the water trap and figured I would pump the lever a few times. I notice that when I push the lever it has resistance, it is moving fuel. However, I have to wait 12 seconds before pushing the lever moves fuel again. Is this normal? It seems if I had to prime the tractor with this it would take forever.
