Trial fit of fuel tank. Several failed attempts with the factory glare shield to firewall angle indicated the piece needed to be removed and an alternative made. Once the angle was removed the tank fit snugly between the firewall and rear glare shield stop. The vent cutout on the glare shield was cut back a bit more to eliminate the remaining interference with the vent fitting, filed and smoothed with Scotchbrite. Drilled out firewall angle rivets. Removed and primed glareshield with Optiflow epoxy primer.

Used a 45 deg AN6 Female/Female adapter to connect bulkhead fitting to inline fuel filter to the AeroConversions AeroInjector. Stacked length of fittings pushes the AeroInjector a bit out of plumb. At least an initial assessment appears to provide an acceptable fit.

Drilled rivets on glare shield firewall angle. Removing firewall angle provides room for tank to move forward in front of stop.
It is my current understanding that the supplied firewall angle was installed to simply hold the glareshield curve during shipping. Will be replaced with the supplied firewall angle SNB-F07-09.
After contacting the factory for a replacement angle, I was told that the supplied angle was an easier installation than the one called out in the plans. Several years later, I understand that Sonex was correct in providing the mount.
Located and drilled for rear tank strap. AN3-20A bolt in drawing is too long. Several years later I regret trying to mount the fuel tank so early in the build without more complete understanding of the kit construction steps.

Test fit fuel tank with glare shield. Having a difficult time getting tank to seat in the last 1/2 - 3/4 inch. Tried removing the flashing with a belt sander to provide additional room, but was unable to fit the tank.
Finally determined that I was using the fuel tank instructions for the legacy model, causing a misunderstanding that the factory supplied the incorrect firewall/glare-shield angle. As now understood, the tank is to be lifted into position and the retaining straps secure the tank to the longerons.
