cheers dude.....u may have saved my day!!! if anyones got 4500 psi it would be even better!!!!! but beggers cant be choosers!!!! will sort you some cash out!!
by the way, im the very tall lad with an impulse!!!
you will be lucky to get much more than a 4000psi fill from a 300bar tank & only a couple at that I've found it much better to take a 3500 fill each time.
