Trim pump parts.

[Alex from GA]

I have a '74 Merc 850 with power trim and need orings for the trim pump. It's an external 4 line Prestolite pump that came with thousands of larger Mercs back then. It takes 6 round and 2 oval orings and I can't find the oval ones. Is there anywhere I can go? Thanks.

This is for the control valve to plate and plate to trim pump, right? If so, the orings are round, and when pushed into the oval grooves, become oval.

Hope that helps....
