If the CG spigot is high enough off the ground, I put the water regulator, then the filter, then the hose at the spigot. Want to keep the regulator and filter off the ground. If it's not high enough, I have a 90 degree fitting from the TT, with the filter next (upstream), then the regulator, then the hose. So the filter/regulator hang from the 90 degree fitting at the TT.
