Alex,

I replaced the mechanical fuel pump with a Facet electronic. I use a regulator 
set at 2 PSI. 

I use the same setup on my 3 and 4. The 3 with SU H6 and the 4 with HS6. All 
set at 2 PSI. Both the 3 and 4 have run with out a problem for the 3 years 
since I switched to electronic fuel pumps.

I don't expect any problems with the 6 with the same setup.

The carbs will have to sit in their boxes for now as the engine is all masked 
up while I continue on the body work/paint etc.
