I would like to consult AACA expertise on the choice of fuel line material for the restoration of a 1925 car.
Previous problems led me to restore the whole fuel supply system. This included laying on a temporary twelve-feet length of simple reinforced rubber fuel pipe, between rear tank and bulkhead vacuum tank, thereby superseding the badly blocked (original) copper fuel pipe (5/16" OD).
I have been able to find a supplier of correctly-sized copper replacement pipe only in the UK; otherwise, the nearest product here in the US would be a cupronickel alloy. I have not yet located a supplier of compression and threaded fittings suitable to it.
But is there now in existence an alternative and satisfactory flexible line -perhaps of armored construction- which could prove much more straightforwards to route along the chassis than traditional metal pipework?
