[TR] Question on Fuel pumps TR3-4

[Don Hiscock]

An original AC fuel pump from the period of our TR3-4 cars would be marked
"AC" in big letters and "made in England".  Our friends in the UK have a
fine resource available to them in the person of Dave Davies, a guy in
Manchester who does superb restorations of fuel pumps.  I have two examples
of his work here now, courtesy of my regular trips over the water and a
number of TR friends in the UK.  He does all the normal stuff for notalot
and even makes a few upgrades, such as the block-to-pump rubber seal shown
in this gallery of one of his restorations.
