 I think it was Don at Aoirflow Performance who told me fuel boils at 130F at
sea level. at 100F at 10,000 ft., and if pulled throuogh a filter to the pump,
at 80F.
 Question: For hot situations like Frded related, does it sound like a good
idea to install a low pressure transfer pump to assure moving fuel from the
header through the 'off' boost pump to the engine-driven pump?  My Airflow
boost pump is on-off, and is located after the filter which is between the
header and the boost pump.
