Was checking fuel pressure, looking for a stalling when idling issue, and that danged cap got away somehow!

No luck with AutoZone, btw. Where should I look to find one (some)?

HVAC supply stores have them in brass.

I expect to find mine the next time I pull my plenum.

I think I capped mine with an AN fitting. Can't remember if it was -4an or -6.
