Installed alternate vent with one way check valve below the 4-way manifold inside the spar. Redid the fuel lines from tanks to sump because I did not like the way the fuel lines were contacting the gear bulkhead as thay went through them. Enlarged the holes in the bulhhead, bent new tubing through it so that it did not touch. Filled the hole with RTV. This should give the tube plenty of flexible support through the bulkhead. Tightened up all fuel and vent connections
