What do you use for sealing the hose to the gauge, any trick your willing to share?
Seems like it's almost daily routine for you trying out different pumps / setups
Ive recently changed out my hose but im getting leaks after holding pressure for a while,
I must have done something wrong
You want to use teflon tape on the threads, and then I also recommend to get the fittings tightened down all the way, sometimes you think it's tight but you can still twist the fitting down another 1/2 turn or so.
I'd also recommend to follow the bleed instructions for the pump make sure there's no air in the line.
