I ordered a new Andair valve direct from the manufacturer right as the pandemic started. It delayed the shipment significantly, but I did eventually get it. They are a relatively small business & were impacted by stay-home orders in the UK. It was less expensive than ordering from Spruce, and I was able to get it with the the countersunk face plate screws which does not appear to be a stocked option at Spruce. I think it provides a much cleaner-looking install.
If you order the fuel line kits from Tom at TS Flightlines, you can go ahead & install them with confidence while you wait for the valve to arrive. I did this & everything fit perfectly. Very happy with the experience & with the excellent customer service.
