I am a new member to TDR and all I can say is WOW. This is by far the most informative site I have ever belonged to. I am NEW to diesels but not new to spinning wrenches as I have been into street cars and bikes all my life. After I bought my '95 2WD,auto,dually last year,I was hooked. The guy I bought the truck from did not know alot about it as he was just a used car salesman. He told me it had a '97 pump (Thats a good thing)injectors and a #6 plate. I know for sure that it has full 4' exhaust with no muffler or converter. It also has a K&N cold air induction kit. Is there any way of identifying injector size???Can the year/HP rating of the pump also be identified??Any help will be greatly appreciated. Thanks.
