Finn,
Per our conversation in Jan at LakeLand, I am 99%
(well, 95%) convinced that your bubbles are indeed due to heating and not air
leaks. When are you going to do a temp reroute of your fuel line away from
the bottom of the aircraft?

I'm beginning to think that it takes very little heating to get
vapour on the suction side of the pumps. Probably especially with auto gas.
The lower the pressure, the lower the boiling point, right?

have not tried returning fuel from the "unused" pump to the tank)

In Paul's case, I am not certain it was
vapor lock since he mentioned he found the his header tank cool to the
touch. Certainly not a definitive temperature sensor - but a
reasonable one. Certainly not to be discounted as a possible source of
the problem and it possibility needs to be confirmed or
eliminated.
