Fuel Tank Closure Cap for Hirobo Helicopters HRB-0404761  [HRB-0404761]

Hirobo GE gasoline tank cap — product overview

The Hirobo HRB-0404761 GE gasoline tank cap is engineered as a replacement closure for fuel tanks on Hirobo Eagle, Freya, EX and SX helicopter ranges. Its purpose is to ensure a secure seal at the tank opening, aiding maintenance and fuel delivery checks.

Use with the specified helicopter families only; confirm your tank neck and thread compatibility prior to purchase. Fitting involves seating the cap and tightening until secure, followed by a static inspection for fuel seepage. Regularly examine the cap and tank rim to maintain dependable fuel flow during bench tuning and functional tests.

During setup and tuning, a correctly fitted cap minimizes fuel pressure swings and helps achieve reliable engine behavior when adjusting needles and throttle settings. Replace any cap showing surface damage, deformation or compromised sealing to reduce variability during preflight checks.
