Hi Pete, I was in the same boat as you needing to fill my Theoben Sirocco and not having a pump I was lucky an FX Pump turned up at a good price so I bought it along with a best fittings adapter kit. Pity you are not closer to me otherwise you could have used /borrowed it I've heard good reports of the bay pumps doing the business plus you will like me only use your pump once in a blue moon
