Overview
The Omix-ADA 17743.03 is a gas filler neck for the 1991–1995 Jeep Wrangler (YJ) with a 15 or 20 gallon gas tank. It is a Direct Fit replacement built to the original Omix-ADA specifications, so it takes the place of a worn or damaged factory neck. The neck carries fuel from the filler opening into the tank, making it a practical repair part for YJ owners restoring the factory fuel fill.
Omix-ADA makes Jeep parts and accessories and backs this filler neck with a limited five year manufacturer warranty. Its listed type is Direct Fit, which points to a replacement for the original neck rather than a modified fuel fill setup.

Working safely on the fuel fill
The filler neck is part of the fuel system, so any replacement is more involved than a bolt-on trim piece. Lowering the fuel level before disconnecting lines reduces spills, and working outdoors or in a well-ventilated space helps keep fuel vapor from building up. Keep sparks, open flame and hot tools away from the area.
Before fitting a new neck, inspect the tank flange and cap seat for corrosion or debris, since a clean mating surface helps the new neck seal. If the rest of the filler system shows wear, such as a cracked hose or weak clamp, replacing those parts at the same time is practical. Old fuel hoses and clamps are often the first failure point, so do not reuse anything that looks worn.
- Disconnect the battery before fuel work
- Keep a fire extinguisher nearby
- Use new clamps and hose where needed
- Dispose of old fuel and parts properly
