Inserted and prosealed vent fitting to on first fuel tank rib. This fitting lets air into the tank as fuel is used to equalize pressure.

Other side of same rib showing the vent line attached to the AN fitting.

The other end of the vent line goes to the last rib and is held in place by an aluminum strip that is riveted to the fuel cap fitting.  Its the highest point in the tank so no fuel will get in the vent line.

Before the tank is closed up, its a good idea to bend the float bar to the correct position so the float will go to the top of the tank and also to the bottom of the tank   The float bar comes as a straight piece of metal.  You have to play with it to get it to fit the tank correctly.

Float on bottom on tank to simulate a "no fuel" condition.

Its also a good idea to put an ohmmeter on the lead of the fuel level sensor and make sure the resistance varies as the float moves from the bottom position to the top position.  These Stewart Warner senders are actually used commercial trucks (big rigs) and Vans adapted them to the RV series.

Fuel tank is ready to have back plate installed then to be pressure tested for leaks.
