I installed the doubler and the gascolator tonight.
I got everything located and drilled yesterday and today I cleaned up the holes and dimpled for rivets. I also enlarged the hole for the fuel line elbow that transitions through the firewall and into the gascolator. With everything ready and the doubler primed, I riveted it into place.
Applied a small bead of sealant to the back of the gascolator and bolted it into place. I installed the elbow and fabricated the fule line that goes between the aux fuel pump and the gascolator. I must be getting good at bending tubing--it only took me 20 minutes to make the fuel line. :-)
