I bought a repair kit for my fuel pump from a local Mercury dealer, when I opened the fuel pump, the diaphragms was split and one of the check valves was in wrong (both facing up) and one was mashed because of being in wrong. Went back to dealer and he sold me another kit with the check valves plus it had a Block filler that held the check valves in place and a spring with a cap that clipped on top. The block filler screw holes lined up where the check valve old retainer screw in. Everything fit and boat runs great once you are on top of the water, but a lot slower getting out of the water before very fast coming out. Could that spring with the cap be causing this or what is the reason for the spring? I have looked at part list and none show the block filler or the spring with cap for my model.
