[TR] TR2/3 fuel pump flex line

[Angelo Graham]

Hello List:
  I just installed a NOS steel wrapped flex line between the fuel shut 
off valve and supply side of the pump on my '2. . Not sure of the age, 
but it has never been used. Am I courting problems here? Will the rubber 
interior line stand up to our "new" fuels? I can keep an eye on the 
sediment bowl for any bits of debris, but not sure if the rubber inside 
line will just collapse or otherwise deteriorate.
Any alternatives to this set-up? Wondering about canabalizing the 
existing line for the fittings and graft rated fuel line to the ends.
Thanks for any help with this.
