Replaced the delivery valve seal and copper o-ring. Got the spline socket from the dealer. Seal and o-ring from the local diesel injection specialist. Just gave them the Bosch Inj Pmp SN#. They had it all in stock for $2.58 a set.

Turned out to be a simple job. While I was at it, I wanted to replace the primer pump with the new Bosch pump. But I had a tough time unscrewing the fitting where the primary fuel filter goes in to. I just could not budge the 22mm hex fitting. Its a tight spot down there and the stubby combo wrench could not do it. Have to remove this fitting since its in the way of removing the old pump. But, since the old pump still works ok, I backed off from doing it.

Can't believe how easy the car starts now. It was 25 deg this morning and it started at first crank

. I believe its due to no more leak in the fuel and injection system.
