quote FrankR:

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”

Thanks for the measurements, Frank. I have done tap and die jobs on things id rather not mention…lol like broken bolts down deep in engine blocks that when i recall them, i still cringe…haha so this looks a bit like fun. i just like the option of being able to go back to stock on things.

with that being said would the above bypass cover work on my engine?
