Propane Tank from UK

With the recent shortage of undermount lpg tanks, I've considered ordering one from the UK. I'm hesitating because their tanks don't have a bleed valve. Of course, they include an OPD for 80% fill but no bleed valve. Are bleed valves required on permanently mounted rv tanks in the US, or will I have to add a bleed valve to be compliant? Thanks!

Bleed valve.......Fix Liquid Level Gauge
The only proper means of confirming tank is not overfilled (above the 80% liquid level)
OPD is NOT to be use as Primary ----Fixed Liquid Level Gauge IS

*Attendant cracks open 'bleeder valve' when filling
Vapor vents out until 80% liquid level is reached ---then spews Liquid Propane
Stop filling/close bleeder valve

Fixed Liquid Level Gauge
Valve that screws into tank wall and is connected to a Stand Pipe which has an open end at the 80% level
NOT something one just Adds....built in during manufacturing

LP Tanks are under the jurisdiction of the American Society of Mechanical Engineers & National Fire Prevention Association

Tank Internal components----Left to Right
Level gauge...magnetic float assembly
Pressure Relief Valve/Stand end in Vapor Zone
Fill Valve/OPD
Fixed Liquid Level Gauge/Bleeder Valve---open end at 80% level
Service Valve/Stand end in Vapor Zone

I can see how a tank manufacturer in the UK making tanks for use in the UK could not give two figs about what ASME specs say but I would wonder they would purposely not equip a bleed valve? Seems odd. Different fill procedures/equipment over there?

If the fellow filling your tank is sharp, he may check to make sure your tank is ASME certified and approved.

I think it would be better to stick with a Manchester tank made here in America.

OK, I haven't had MY RV tank refilled a whole lot but my refillers have so far seemed to fall into one of two categories. Either so bored with life and their job they don't care about anything or "OMG OMG, I'm not sure about any of this. I only started here just last week." Not a single "sharp" one yet.
