Hi Folks-I need your guidance please-I am new at this. Working on a standby Diesel Generac. Replaced the Stanadyne Model 80 Filter and assembly, re-attached all the hoses etc. and now the unit won't fire. I can't find the procedure on how to bleed/prime the filter...Is that required...Can anyone shed light on where I am going wrong.? Appreciate any help with steering me in the right direction. t
