Bought myself a 2nd HP 4500psi preset for a spare, and its decided it wants to misbehave and has started leaking from the pin .. Was fine when i bought it until i ran it out of air today and now it wants to leak every time i fill it up...
Ive tryed to get the reg bonnet off to give the inside a quick clean and check for dirt but i can seem to budge it.. doesnt appear to be any grub screws holding it on like on my pmi reg so does it just need a little heat etc to remove the bonnet from the reg???
Alternatively will the pin deside to stop leaking if it get a decent pressure inside, was only getting a very slow fill upto about 3k today..
Any ideas ???
