Combined fuel tap and filter - what model?
« on: 22 Nov 2013 at 09:25 »

This petrol tap and filter is made by Ewarts, and is stamped on one face of the top hexagon with the Douglas DK trademark.

From the patent date, it would seem that this "improved" model (with the horizontal outlet, so that the filter can be removed and cleaned without disturbing the fuel line) would have appeared about 1925 or 26.

An expensive item - can anyone say what model Douglas used this tap?

Leon,

My F28 (600EW) uses this very same tape. My (former) electroplater lost the hex cap on the bottome with the Ewarts stamping after I had spent a considerable time reconstructing a buggered up hex. The 350EW also used this tap, and I would expect also all the Douglas models (excluding the TT) during the 1926-28 time frame. Probably even some of the later 2-3/34hp models had it.

I am not sure just when the started or stopped using this petrol tap. It was a bit fancy with the built in filter and a position for draining off some fuel for priming cups.

Thanks Doug and Edin - I'm not surprised that is was used on the big bikes, but the 350 EW surprises me as I though that model would have been built down to a price, and choosing a cheaper tap would have been a good way to save a few pence. The RA used an earlier version of the tap, where the outlet was in line with the filter.

Hello,
What's the thread (both) of the tap ? Do you are certain is the right one for EW350 ?
Thank you.
