i have a dixie chopper that has a very small leak on the left hydro pump. about 10-20 drops a day after using it. will this make it threw the year, and how hard are they to change out. i am planning to ride it out this season if i can and replace the pump myself this fall. its leaking where the pump attaches to the center box part, i don't know if thats just a seal there or the pump need to be replaced.
