Primer Line routing through firewall ??

Let me check my GPS, gee how'd we ever navigate w
Do you use firewall fittings for the primer lines or do you just run them through using a grommet or other protective measures? Also I've been looking for a restrictor fitting for the oil pressure gauge line for a Cont O-200 and haven't been able to find one, any suggestions on where to find one? Thanks

Make one by welding, soldering or otherwise plugging your fitting closed, then drilling a .040" hole in it.

Piper used a grommet. Oil pressure restrictor is Item 34 Figure 10 in the J3 parts manual.
