I have in mind old VW 's  -- so there.

I have in mind old VW 's  -- so there.

The word today is " Viscosity"    so aside from vane-pump what else is affected ?
The fuel regulator valve is   (adjustable)  And the orifice in outlet banjo is fixed.
So heavier diesel less flow  ergo more pressure in pump.  VW  demands # 2. 
diesel for those reasons.  The timing piston allso gets sloppy with times.
The cumulative effect of all these things . Gives a lot of us problems.

So as Loren observed  " Hillbilly tuning" advances pump to compensate for
the missing dynamic timing advance.Plus all the other factors.  
In simple Ham language we tune for maximum signal , not from numbers on
the dial. -----And it works.
