Of course in true Cummins fashion they all need primer and paint, so I am outside at the truckstop painting them on some cardboard in the dirt. I will install them tomorrow, hopefully the end of leaky number 5.

What size socket is needed for the part in the middle? I know fuel lines use 7/8 crows foot...
