Hello all

Dave , I have no extra support for the just the exhaustheader.
How thick are the walls of Your tubing?
It sounds like the pump You got is pretty powerful.
Do not plumb the suction pump straight into the oil return !
Then You will suck the bearing dry. Use a mini oil pan.
Blocking will not cause the bearing to break, it will just blow
some oil out the sealing. it happened qite often on My old

regards / Christer
