My understanding is that the Rewarder and Bassett T's are regular flare (JIC) type, but AN is fine, especially at the low pressures we're operating at. I have one of each here, but musta got rid of all my -8 AN hose ends somewhere else I'd verify that. I don't think it matters, 'cuz I've run with AN fittings and even 5/8 hose shoved over with a hose clamp with zero leaks. Well, ONE.......but that don't count because the hose clamp forgot to tighten itself before we got on the lake......
