I think that you should check the pipe system on your vehicle! Is the tank bolted to the undercarriage or cylinders (safefill or others) as they have a non return valve built in , if the gas escapes when you remove the pump you have a serious problem, best get it looked at ASAP. ED. PS. PIGTAILS ALSO HAVE NON RETURN VALVES BUILT IN.
The tank is bolted to the underside of the vehicle and is designed to take up the space once occupied by the spare wheel. The flow pipe is solenoid controlled at the tank and at the engine. The return pipe has a non-return valve at the tank, which prevents gas escaping from the tank in the event of damage to the pipe (according to Vialle). The filler pipe has a non-return valve at both ends (tank and filler port), to prevent gas escaping in the vent of damage. The tank itself has an internal valve to prevent overfilling, thus 80% maximum fill. Hope this answers your question.
