FYI,
Sure sounds like a pressure problem, but if it's not, Cambridge Motorsports
in merry old England sells a high quality Silicone version of the TR3 top
hose. I have one on the shelf for the next failure. FWIW, a radiator
pressure tester would rule out exhaust pressure as a cause of premature
failure.
