Everything is included for comolet rebuild of your fuel pump. Worked well on my 2004 mercury 90hp 2 stroke. This is the same kit many different size mercury and mariner engines use

This kit fit the pump on my 1995 115 hp Mercury. The directions were clear and easy to follow. I didn't have any problems putting in the new parts and this is the first time I've rebuilt an outboard fuel pump, although I do have mechanical experience with other parts of the motor. I'm happy with the purchase and would buy it again.

Was exactly what I needed. Buy this and rebuild instead of buying a Chinese knock off pump replacement. It's easier than I thought to rebuild.

My Merc 40 started acting sluggish and would stall when accelerating. It would barely run at half-throttle and eventually stall. However it ran fine at full-throttle. I replaced the primer bulb first with no change, so this was the next step. It was easy to do and had clear instructions. Motor runs perfectly now at all speeds. 4 Stars instead of 5 because the instructions said to reinstall the fuel up and torque bolts to 50-60 pounds. NO - It should be 5-6 pounds instead. BIG mistake. However, it listed the 'newton-meters' correctly.
