I need to order the fitting for my AEM rail so I can use the OEM fuel line. Do I need the one with the hole or without. The OEM rail doesn't have the hole but I just wanted to double check before I order.

 

when i ordered mine, i ordered PART #:2-603. it has the hole for the banjo bolt. the issue i had was that the threads did not match up, but back then i was in a pinch and "stripped" them on. never leaked for 2 years. its not ideal but it works.

the correct thread pitch i needed was PART #:2-602 but it didn't have the hole.

if i was to go back i would get the second one and drill a small hole. after all of that i found out that as long as you have the correct "free flow" head, you do not need the banjo hole in the stud.
