[Vwdiesel] Pump timing/Reading a dial indicator

[slatersfb at aol.com]

I prime pump before final installation of belt & timing. Crack all lines at the injector, 12 volts to stop solenoid & use 600 rpm electric drill to spin pump. When fuel pisses out at injector, stop. Install belt, tighten everything up, time the pump & engine starts instantly. Save that $200 starter. Works every time.

I use an "IV Drip" methog, hang a container from the open hood with su[[ly
and return lines, start the syphon, and the drip will fill the pump. the
engine will start almost instantly, and you run it until the air is all out
of it.

Then you connect the tank, restart, and watch for bubbles.

If there are a lot and they continue forever, you have other problems with
the lines.
