Cat C7 secondary fuel filter
After 30,000 plus miles on my C7 Cat I decided the finally change to secondary or final fuel filter that is mounted on the engine. I did some research and there was a thread in this sight with all kin...

Caterpillar's official position (I know, I present the Caterpillar Maintenance Seminars at FMCA Conventions, Diesel RV Club Rallies, etc) is to install filters dry IF, repeat IF you have a manual primer pump. Done it probably 100 times over the years-- never a problem.
BUT, if you do not have a manual pump (or until you install one which just takes removing two bolts on the secondary filter head and installing the pump in the place of the block-off plate) DO NOT INSTALL THE FILTERS DRY.
Instead, slowly fill the small outer holes which are the filter inlets.
