Continued from #52a. 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. Hagar. may be continued.
