Europa-List: Fuel smell 912S XS front fire wall

[ctsmallwood <ctsmallwood@onetel.com>]

Hi All
Occasional slight  SMELL of fuel. ALL connections fully checked.
On both sides of fire wall(with developer).Fire Wall sealed prior to engine fit,
and again after  engine/ flights.All Ally fittings aft. firewall
Only place I believe it may be originating from is the Air Box.
2 small holes under each connection to the Carbs(in Airbox).
and entering cockpit thro throttle and brake slots via tunnel
Any help greatly appreciated
Regards
