My fuel pump seems to stop buzzing under heavy acceleration, as if a 
drop in line pressure allowed it to stop straining/cavitating for a 
moment.  Could this be, or am I imagining things?  I hope to investigate 
this further when it warm up.  Maybe there's too much pressure in the 
line for the OEM pump to handle, it sounds like even new pumps with new 
filters don't last long.  Perhaps I could add a booster pump in-line to 
relieve the OEM pump.  How is the fuel rail pressure regulated?  Back to 
my Bentley again.....
