Fuel tank bulkhead fittings

Do I need to install the fuel fittings on the inboard fuel tank with proseal? What I mean by that is can I install everything dry and then coat the inside and outside with proseal or should I apply sealant to the shoulder of the fitting as I install it into the rib and torque it down? Then come back and encase both sides in sealant.
 
Be sure to clean the area on the bulkhead thoroughly as well the fittings. Apply sealant to the fitting shoulder, a bit of the threads, washers & nut than tighten down. Follow up by applying a bead over the nut and washer surfaces on the inside.

For the 1/4" vent bulkhead fitting, install the fitting from the OUTSIDE and the washer & nut are on the INSIDE.
