Protect yourself from fuel contamination by visually checking the fuel for water and debris. Fits all quick-drain valves and has an adapter for recessed drains. The transparent cylinder is 6" long with octane color-coding molded in the side. Also includes a screwdriver blade with both Phillips and slotted heads.


Excellent piece with a nice box to keep it in. Just like my older ones that Ive had for years. This one is so clear. Get one, you wont regret it.

Lost my fuel tester and replaced it with one from aircraft spruce. Its a simple tool and seems to be constructed to handle pretty rugged use. I am very pleased with this product and everything I purchase from Aircraft spruce.

Tester for the fuel, screwdriver, for the cowl fasteners. Unscrew the housing and the screwdriver bit reverses, slotted and Phillips. Buy several, one in the headset bag, your car and the aircraft. Buy one more for that student pilot you meet that needs a helping hand that day.

Works great, does what its supposed to do, at an affordable price. The dual tip screwdriver feature is just icing on the cake.
