This is the basis for the can of worms that Alan means:
3. (1) Every connection for filling a fixed gas container shall be on the outside of the vehicle.
(2) There shall be fitted to every fixed gas container either—
(a)a manually operated shut-off valve and an excess flow valve, or
(b)a manually operated shut-off valve and a single check valve, or
(c)a double-check valve.
and all parts of these valves in contact with gas shall be made entirely of suitable metal except that they may contain non-metal washers and seals provided that such washers and seals are supported and constrained by metal components.
(3) In every case where a pipe is attached to a gas container for the purpose of filling the gas container there shall be fitted to the end of the pipe furthest from the gas container a check valve or a double-check valve.
(4) There shall be fitted over every gas filling point on a vehicle a cap which shall—
(a)prevent any leakage of gas from the gas filling point,
(b)be secured to the vehicle by a chain or some other suitable means,
(c)be made of suitable material, and
(d)be fastened to the gas filling point by either a screw thread or other suitable means.
It's the relevant section of the Construction and Use regs.
He and I kicked this one around a few months ago on here as to whether the remote filler can be fixed just inside the locker or has to be out in the day-light as it were.
Also the industry code of practice does say that to be considered safe by pump attendants the fill should not be directly onto the bottle. Gaslow do a leaflet that outlines this.
Those are just some of the worms.
