Just spoke to Martin and although he can charge up to 3000psi, he will have 4500psi next year. His fill system has an 1/8 bsp female at the end, which is the same thread as the quick dissconnect adaptors we use. i will pop down there tomorrow to have a look and see what i need to sort it out.
P.S. Jo are you a student.
