I ran a m8x1.25 thru the smooth bore above. The correct drill size for a m8x1.25 tap is 17/64

Since it is a straight thread I am going to use some pipe dope to help prevent leaks. I ended up using 3/8 barbed fitting because I had 3/8 fuel line laying around. You could use 5/16 barbed fitting and hose. I just have to cut my return line and Tee into my factory return line to my tank and its complete. I plan on bracing some because of my homemade fitting has some weighting to it and I don't want to broke my injector return line

Had time to get a picture of it. So far no leaks
