I have the o-rings from diesel o-rings (1 large for backplate,2 small for solinoid). I removed the backplate and piston from bore in the pedestal. Wher is the solinoid located that has the other 2 o-rings ? how do i access it? i assume its in the front of the pedestal where the wire connects to? How does it remove? Never mind I think I got it by removing the nut on the front...
