I only fitted one vent on top of the fuselage as detailed in the build
manual. One vent was not required as I discarded the fuel sight tube when I
fitted the capacitance fuel gauging system. In practice I have found the
vent, close to the filler, very useful during refuel. The hissing of
displaced air and the bubbling gives a very good indication on approaching a
full tank. Saves unnecessary overflow, which invariably runs down the
fuselage side and into the flap slot, causing a bad fuel smell until it has
all evaporated.
