cool... i gotta Viking tool kit arriving which comprises of a gauage adaptor for the back of the gun, i back out on getting the huge standard 0-700 guage in the kit as they were far too expensive and assumed i could get a guage more a closer range to what the viking cycles at
the standard guage is 1/8"npt. and im going to use a 0-300 ashcroft guage off a timmy, both are american so would assume it would be fine
