REFLECTOR: Hydraulic Pump Leak

[Scott Derrick]

Jeff,

I found the screw finally. I remember wiping off the bottom, but the hole 
in the middle was filled with dirt and crap and I figured I'd clean it out 
when I got the reservoir off.  Wouldn't you know it the one screw that 
holds it on was in that hole!

I guess I will reseal mine with some kind of RTV or Silicone.  Its not easy 
to get that stuff to stay sticking around hydraulic fluid.

This pumps not made for vehicular use..  At least the reservoir sealing 
mechanism isn't..

I screwed up the two little filters and will have to make new ones or find 
replacements.
