My SPF clutch reservoir is leaking. I noticed the fluid level was down some, topped it off, couple of days later rechecked and down again. Checking things over, NO leak at the 3/8 hose connection on the bottom, NO leak from the cap on top, the seepage is from where the plastic reservoir joins the plastic base component that bolts to the firewall. Diagrams I have found on this Wilwood 4 oz remote reservoir system is that there is an O ring that seals the top container to the base and a clamp is secured externally around that area. I'm going to replace the reservoir but wondered if anyone recommends any particular sealant or technique of installing to prevent leaks from the 0 ring area? Is the O ring to be lubricated or treated somehow when assembling? This is just the reservoir on the firewall, not any part of the high pressure hydraulics, so it is apparently just a gravity leak from the Wilwood assembly Thanks for any advice
