Luso Aviation Fuelhawk aircraft fuel gauge for Cessna 172 — 11" tube, calibrated 19 gal usable, aviation-safe clear plastic

This compact, purpose-built gauge is calibrated to the Cessna C-172 with 19 gallons usable per tank and manufactured from durable, aviation-safe clear plastic that resists yellowing, fading, and cracking. It provides a simple, portable secondary method for estimating tank contents when exact weight-and-balance calculations or partial fuel loads are needed. Because it is tailored to a single make, model, and usable capacity, it’s essential to use it only on the aircraft specified and on level ground.

How do I use the Fuelhawk to check my Cessna 172 fuel quickly?

Using the Fuelhawk is straightforward: insert the tube until it contacts the tank bottom, cover the open end with your finger to trap fuel, then withdraw to read the fuel level in U.S. gallons. The process takes only a few seconds and requires no tools.

• Insert tube fully until you feel the bottom of the tank.
• Cover the top opening with your finger to capture fuel.
• Remove and read the calibrated marking showing usable gallons.
• Repeat for each wing tank on a level surface for best accuracy.

What makes this Fuelhawk suitable for aviation use and long-lasting?

The Fuelhawk is made from a heavy-duty clear plastic formulated to resist common forms of deterioration such as yellowing, fading, and cracking from exposure to fuel and sunlight. It’s built to be safe for aviation fuel contact and durable enough for frequent ground checks.

• Heavy-duty clear plastic resists discoloration and brittleness.
• Designed specifically for contact with aviation fuels.
• 11" overall length fits standard Cessna 172 tank depths calibrated for 19 usable gallons.
• Made in USA construction and quality control.

When should I rely on the Fuelhawk versus aircraft instruments?

The Fuelhawk is intended as a secondary, manual method to estimate fuel quantity and not a replacement for certified aircraft fuel gauges or official procedures. Use it when filling a partial load, confirming suspected gauge errors, or when precise weight management is required.

• Useful for verifying suspected instrument discrepancies.
• Handy when taking less-than-full fuel loads for weight control.
• Not a substitute for AFM/POH procedures or certified fuel indicators.
• Always park the aircraft level before using the device.

Who is this for? The Luso Aviation Fuelhawk calibrated for the Cessna 172 (19 gallons usable) is ideal for flight instructors, private pilots, and maintenance crews who need a fast, low-cost method to verify usable fuel on the ground. It suits operators who frequently adjust fuel loads for weight-and-balance or who want a reliable secondary check when gauges are in doubt. Remember this is model-specific — use only on the C-172 with 19 gallons usable per tank and follow your AFM/POH for official fuel system guidance. The user bears responsibility for confirming accuracy and proper use.

• Features: calibrated for Cessna 172 w/ 19 gallons usable per tank, easy to use, aviation-safe clear tube, made in USA.
• Caution: use only on the specified aircraft model and capacity; aircraft must be level; consult AFM/POH for definitive fuel information.
