Pushlock fitting on AFPR question

[Royal-T-Ltd]

What thread size are you guys drilling out your existing vacuum port to? and any problems or tips on the install?

I just tapped it out to 1/8inch npt. Can't remember what size drill bit though. Look that up on a drill chart. Just go slow and check the depth of the fitting often. You can always tap it deeper.

1/8" NPT here as well. If you have the tap it will say what size drill on it. I did it on an Accufab so it was easy to take the top off to ensure I didn't drill/tap too deep. Pics here:

thks. i have a lot of push lock fittings too. i bought 1/8npt for my accufab AFPR but it looked huge compared to the hole already in it and was wondering what size everybody was using. i didnt want to drill it out too big for no reason.
