Accusump plumbing

["Jack W. Drews" <vinttr4@geneseo.net>]

I plan to plumb the new Accusump directly into the oil gallery, since I 
have the engine out and can drill and tap properly.

The Accusump comes with 1/2 NPT ports. Tapping the block for this size 
seems pretty big but I do want good flow.

Fittings seem to come with 3/8 NPT to 6 or 8AN, and 1/2NPT to 8 or 10AN.

My tendency is to use 3/8NPT to 8AN.

Question for you guys who are plumbed this way -- which size do you use?
