Ok,.. what about this one:
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=110174410189&sspage name=ADME:X:RTQ:UK:11
I asked the seller a few questions,.. here's his reply:
Hi, thanks for the inquiry. No, the unit does not have an internal pump - however your 12v pump will operte with the unit just fine. The maximum pressure is around 150psi and the absolute minimum is 10psi. The default is "off" if the unit senses that there is no water, gas, overheat, etc. It is top vented. The gas burnoff (carbon monoxide) would be harmful in an enclosed area so we only recommend the unit be installed outdoors only. It comes with a 1/2" to garden hose adapter and a CSA approved LP regulator for use on a standard grill propane tank. The unit has 1/2" standard fittings so if you wanted to put it on a smaller or larger unit, you would be able to find an adapter. I hope this answers your questions and please do not hesitate to contact me with any further questions.
