OCD taking over here ... but I would bet no one ever thought to check the ID of their brand new AN-3 fittings! Well I received my Fragola fittings for the brake lines, mainly bulkhead fittings and some 90 and 45 degree fittings and after inspection I noticed there was a difference in the 'shoulder' of many of the fittings at the 37 degree flange. So I investigated the difference and found the straight through fittings would easily accept a 1/8' drill bit … hmmm, so I went through the entire order of fittings and made them all 1/8" minimum. I put the drill bit in the vice and 'hand drilled' the fitting onto the bit. Most obstruction came from the bulkhead fittings with 90 and 45's that weren't drilled all the way through to the end [if that makes sense].

Definitely time consuming, but a task I needed to get done to ensure all ID's were the same. Pictures may not be that good but you get the idea











I got the brake lines mocked up and will steady the course and continue the task of routing the brake lines …. thanks for looking!
