    If you are going to buy a newer bypass cover, use the 18-7351 fuel pump that I posted earlier

    If you are going to drill and tap your bypass cover, use the Mikuni pump that you posted. You would use a 5/16" drill and a 1/8" NPT tap.

    It kind of sounds like you don’t know what that is. It might be easier for you to bite the bullet and get the bypass cover and 18-7351. Besides, that would make it "Factory"
