Tim,

I know this issue has been talked about many times in the past but my 
advice is to replace the stock pump with a Facet or similar pump mounted 
close to the fuel tank. Remove the mechanical pump and replace with a 
blocking plate.

I mounted a fuel regulator where the pump was on all my 3 Triumphs. The 
4 was done first well over 15 years ago and no problems. The 3 followed 
a year later and when I did my 72 6 it got the same treatment.

All 3 have been flawless. No leaks, drips or errors! And when I turn on 
the ignition, the carbs are primed by the time I pull out the choke!
