My 04 LB7 wont start. Changed fuel filter. Still wont prime. I have ordered the deluxe fuel filter head rebuild kit and am awaiting the arrival of these parts. I have read that some of you recommend pressuring the fuel line by using a shop vac or leaf blower? Could you please describe this process in detail? Also, should I put fuel in the filter manually? I have read some posts that say you do and some that say do not do this. I need clarification.
