[Vwdiesel] Injection Pump testing ---( the fuel flow test )

[Svend M Kjong]

Isn't there also a pressure regulator for the vane pump?

Andrew

Svend sez :     yes Andrew  -- BUT NO it is NOT a pressure regulator  --it is a SPECIAL
modification of a Pressure regulator.  ----remember the pressure in the housing has to
change according to RPM.----BUT you are right it is a Regulator and it IS
adjustable  ---That regulator and the ORIFICE  --are working in unison to feed the right
amount of  fuel , to satisfy the timing piston.    Can a DIY adjust  the regulator valve
? --yes I do it all the time. And the way I do it will follow . But Andrew you are jumping
ahead a bit.
After the Flow test show that pressure in housing is LOW  ---then we do a number of
things --and adjusting the Fuel Regulator valve is on the LIST.

Svend ,

PS :  This is where the border between Chore and FUN  --begins. (for me) ---In my case the
only chore is testing Tire (Tyre) pressure ---- BOSCH IP.s ?  never a chore for me.
