A lot of things won't stand up to modern fuel. At the VTR/Triumphest last
year, I had a feed hose from the tank to the fuel pump start leaking. I
replaced it with a Teflon lined hose that was quite expensive but well worth
it for piece of mind.

If it was really NOS, you might want to consider changing the diaphragm
sooner rather than later. The original diaphragms won't stand up to our
modern 'oxygenated' fuel, and will very likely start leaking fuel out the
weep hole (or into the crankcase).

That's interesting. I had a similar problem with my original TR3A radiator,
but it didn't seem to have ever been soldered. Apparently, the tubes were
just pressed through the fins, and either thermal cycles or corrosion had
loosened them. I'm thinking I may have a similar problem with my current
TR3 radiator, which was apparently recored many decades ago with the same
type of core (but no crank hole).
