    Looking for MFI Part # for Return Oil Seal

    So I have a freshly rebuilt MFI on my '70 911E and as I'm test driving it I found a pretty big oil leak. It appears to be coming from the cover plate on passenger side of the pump where the return oil line(??) is attached. I checked the parts catalog but don't see anything shown for the gasket. Any ideas on where to find one?

    Thanks

    Chris

    Thanks beh911! Ever used fiber or cork rather than neoprene rubber?

    Why didn't the rebuilder use a gasket that doesn't leak ?

    I pulled the cover off the other day and the gasket was fine. Not sure why it was leaking. I did find some type of silicone on the gasket so I cleaned everything up, reinstalled it and no leak. I haven't gotten it up to operating temperature so I don't know if things will change.

    If those gaskets get over tightened, they can leak. I always use a thin coat of curil t on both sides.
