Fuel Filter Replacemnent and other Difficulties- Be Prepared!
When my '82 300DT lost power on the freeway I managed to nurse it to my destination and got out my fuel spare filters. I installed a new prefilter and main filter, bypassed the FM10 water separator, pumped on the hand pump, and then found that the lack of a 17mm end wrench made bleeding the lines at the injectors real difficult as all I had was an adjustable wrench. Too bulky for that job. Then I screwed up by not reading Kent's instructions carefully and ran my battery down before the fuel lines were bled enough to get the engine going.
