Gene Berg takes a Schadek high quality 26mm pump and enlarges and aligns the oil galleys then hard anodizes them for long life.
An o ring is also fitted to the pump housing to prevent oil pressure from bleeding back into the crankcase.
This pump is also pre plugged for use with full flow oiling systems.
These are 26mm pumps, late style for dual oil pressure relief cases and running a "flat" 3 bolt camshaft.
These are the best oil pumps on the market!
Gaskets sold seperately!
