My trim pump (#21945915) is leaking hydraulic fluid. Can I get the lines fixed or do I have to buy a new pump?

You can purchase the top cover that will go over your old existing pump.   It comes with a cover and
the four new hydraulic lines.   This cover only work around was made by the Europeans who screamed
about having to purchase a whole new pump to fix the leaking hydraulic lines.

So Volvo Penta would like you to purchase the whole new pump assembly which includes the cover,
but you don't have to.

If you are just having some leaking issues around
the hydraulic lines then go with the cover, but if your pump is making noise or you have to jiggle
the wires sometimes to get it to work then go with the whole new pump.
