Many thanks DavidAU. Google did find that link for me but I dismissed it because the first page described an electric fuel gauge, I did not look further. I now understand the purpose of the the two extra tubes. Hopefully we will be able to get the gauge working, it appears we may be only missing the small hand pump. There are a lot of Rolls parts in the shop, a good search may turn it up.
An Enots oiler showed up and we have worked through all the dripper plugs of the Bijir chassis lubrication system (an amazing pump, the one in this car puts out 80 psi at the start of the stroke)
Currently working on roof covering, carpeting, upholstery and head cloth in the Packardward body.
