I have come into possession of a new, 17 gal 1.8HP 150PSI oil-less, air compressor (it's this one from HF: https://www.harborfreight.com/air-to...sor-68066.html)

My son-in-law and I plan on using it for the car repair work that we do, as it also came with various 1/4 and 3/8 ratchets, and a 50' 3/8" air hose (I believe it's pvc/hybrid).

He is suggesting that I upgrade all the fittings, hose, etc. to be 3/8 instead of 1/4 to get maximum airflow.

I have no idea where to start, as the title says, I'm clueless when it comes to air compressors & fittings/connectors/couplers! I only know how to put a few drops of oil in, and go... And I do know there are basically 3 types of plugs/connectors: NPT, Auto and Universal! And something called high-flow (H)...

Can anyone give me some specific products, links to products, that I need to acquire in order to change all the 1/4 fittings to 3/8? I believe this uses the standard 1/4 NPT fitting stuff.

I was told to get a filter also to go in the air hose 'line', so I assume that needs to be 3/8 as well?

Thanks!
