Review on 🔧 KIPA R12T Fuel Filter Water Separator 120AT NPT ZG1/4-19: Complete Combo Filter for Automotive Racor R12T, Marine Diesel Engine, Outboard Motor - Durable Spin-on Housing (10 Micron, 3/8 Inch NPT Fitting) by Brian Cooper

Filter works great having bought quality NPT fittings. I recommend buying the filter separately, not the kit. I'm not familiar with the barb fittings, but the NPT plugs in the kit are not airtight. Tried several times with various pipe thread sealants, but without success. I bought a second set of filters thinking I overtightened and snapped the thread. No, the candles were still flowing. Bought high quality NPT square plugs and they sealed on the first try. The other two fittings received an off kit NPT tube and adapter, both soldered the first time.
