Nice ! I never get water that is actually enough to drain out of mine. So I just leave the top cover off when it isn't in use so it just dries out between uses and doesn't stay damp
I also put a good amount of silicone lube on the o-ring on the cap so it lasts. As far as longevity goes, I have filled my 9 liter tanks like 20 times with no visual difference or loss of pressure or fill time at all. So i would think it would last a long time as long as it doesn't get moldy from leaving the cap on.
Doesn't the filter need to be upright so the water sinks? Does the metal filter cap with the bolt in the side need to be at the bottom to drain water? I don't have one just guessing? Nice kit Roy.
It shows the outlet is that way so I'm going with what they telling me here on instructions and yeah it should be up right I would think but this is the best I could do by having the gun higher than the hose for now until I get that bracket made
