I thought the " in high detail" includes the tools and procedures, too. What you answered is nothing specific, it's obvious. I'm interesting in how to access the bolts to remove them and replace them!!??
Sorry, Ron, may be I'm wrong, but there are six bolts on my oil pump, four size 10 mm and two size 8 mm and the upper three are really hard to access with a simple wrench, they are in a very tight place.
Yes, you are right, may be a 3/8 will do it! Thanks for your answer!
