I called the diesel injector shop myself first thing this morning. They were able to verify that 6 injectors were brought to them for cleaning and testing. So the injector work did take place but the shop broke 2 hoses in the process and replaced them with sub-standard hoses. Much better than my suspicions of no work done.

After I complained about the hoses and the mess the shop took money off the bill and got me a length of new hose. They offered to put the new line on but I declined.

So its on to the delivery valve job. I have viton seals on the way and I picked up the copper washers yesterday. I still need to rent a spline socket from someone. New ones are $50!
