Thank you so much Back_Roads for posting the helpful link. I too am interested in a starter setup for PCP filling. Will that whip hose extension listed down in the "frequently bought together" work with the Hatsan nozzle. I am a complete novice to PCP's so bear with me. I assume the Hatsan fill nozzle has the standard 1/8 thread. When looking at the sellers' websites online, the way fill options are marketed is confusing. When looking for PCP hookup options, many expensive tanks and pumps are presented. I have no doubt this has scared off many potential buyers. I am glad cheaper, effective options are out there.
