A 12V S.U. fuel pump.It was rebuilt over 20 years ago and has been in a box in my garage ever since.I recently tested it and it works perfectly. However, I do not know if the diaphragm is compatable with modern fuels. So it may be necessary to change this before use. It is fitted with the wrong cap, which is for a 6V unit. Otherwis..
Broken down. Not working. Could bake a working engine from the 2. Found in grandfathers / uncles garage along with large amount of other de Dion parts..
