Should be able to remove gland seals and orings, and bring them to a seal shop and match everything up.

Thanks guys,

I plan to pull the bad one apart this weekend and see if I can get the parts.

It would be wise to do all four or else you may be revisiting this issue. Also clean out the trim pump reservoirs to clean out any particulate/water contamination.

My plan is to pull one and take it apart, if I can get parts easy enough then I will buy enough to do all four. Right now I am in the process of making a spanner wrench to remove the end caps. The pumps are all cleaned, new selonoids and all new wiring!

Thanks
