[Vwdiesel] Filling IP pump

[William A. Thompson]

Exactly how I do it but it doesn't fill the hard lines between the pump and the injectors due to the spring pressure on the internal seat in the injectors.

After filling the injection pump by using a pump on the return line off the injection pump .... I crack the hard lines at the injectors and watch for fuel with the first cranking to get the air out of the hard lines. Then I retighten the hard lines and fire it up.

Mityvac will work but will take awhile due to low volume with each pump.

I use this ....
