I just changed the fuel filters on my newly acquired W124 diesel. It's after I replaced the main filter and proceeded onto the inline, that I noticed that there was no manual hand pump tp prime the engine. I decided to crank her over anyways. The inline filter filled up and I did put some fuel in the main filter. The engine ran for only about 10 seconds and then stopped. I figured there was air in the line and that cranking her would push that through. At this point though I am afraid to kill my battery or kill the starter. Any help I can get would be appreciated. Fortunately this is our 3rd car, so I am not stranded, just frustrated.
