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.
Bob
