I'm a bit confused about high flow fittings and couplers. I can find high flow couplers and plugs, however it's tuff to find hoses, with high flow fittings. If the fittings on the hose aren't high flow, then doesn't that defeat the purpose of high flow couplers and plugs? I tried to find barbed high flow fittings to replace the OEM fittings on hoses, however those are also tuff to find.
Specifically, I'm looking for a 3/8 hose with high flow 3/8 fittings and also, 1/4 npt with 3/8 barbed ends to replace the OEM hose fittings.
