TUELETFU Fuel Filler & Vent Hose Kit for Jeep Wrangler YJ 1987–1995 — 20‑Gallon Plastic Tank, OEM Fit with Clamps

TUELETFU's fuel filler and vent hose kit replaces worn hoses on Jeep Wrangler YJ models (1987–1995) equipped with 20‑gallon plastic fuel tanks to restore a secure, leak‑free fill system.

If your YJ has a 20‑gallon plastic tank and you notice fuel smell, seepage around the fill spout, or degraded hoses, this two‑hose kit is built to match the OEM fit and function. It replaces factory part numbers 52040079 and 52040081 and includes clamps so you can install both filler and vent lines and return to safe, confident refueling. Before ordering, confirm your Wrangler has the plastic tank (not the metal tank used in some 1987–1990 variants) and check the hose end sizes to ensure compatibility.

How do I verify these hoses fit my Jeep Wrangler YJ?

Fitment is strictly for YJ models that use 20‑gallon plastic fuel tanks produced from 1987 through 1995. The kit will not fit Jeeps with a metal fuel tank found on some early model years. Measure the hose end diameters of your existing fittings and compare them to the specifications below to confirm compatibility.

• Applicable model years: 1987–1995 with 20‑gallon plastic tank only.
• Replaces OEM numbers: 52040079 and 52040081.
• Confirm your tank material — kit incompatible with metal tanks in some 1987–1990 vehicles.

What are the exact hose dimensions I should check?

Two distinct hoses are included; each hose has a wall thickness of 3/16". Measure the inner diameter (ID) and outer diameter (OD) on the ends of your current filler and vent hoses to match the data below and guarantee a proper seal at the tank and filler neck.

• 52040079 hose: small end ID 1" / OD 1 3/8"; large end ID 1 1/8" / OD 1 9/16".
• 52040081 hose: small end ID ~3/4" / OD 1 1/8"; large end ID 1" / OD 1 3/8".
• Wall thickness for both hoses: 3/16" for durability and fit.

What comes in the package and how does installation look?

The kit ships with both the filler and vent hoses plus four clamps so you have all basic hardware to secure the connections at the fuel tank and fill neck. Installation is straightforward for a mechanically inclined DIYer: remove the old hoses and clamps, verify orientations, slide on the new hoses, and tighten the supplied clamps to factory‑tight specifications.

• Contents: 2 hoses (filler and vent) and 4 metal clamps as shown in product images.
• Tools typically required: screwdriver or socket for clamps, and basic safety gear.
• Inspect hose routing and clamp tightness after first fill to confirm leak‑free operation.

Are there any important cautions before purchase?

Yes — this kit is specific to plastic 20‑gallon tanks; it will not work with metal tanks used on certain early YJ models. Double‑check the tank type and hose sizes to avoid returns, and contact the seller with photos if uncertain. Keep in mind correct hose orientation matters for proper venting and to prevent fuel odors.

• Not compatible with metal fuel tanks found on some 1987–1990 Wranglers.
• Verify all measurements and product details before ordering to ensure fit.
• Reach out to the seller for fitment help or questions — customer support is available.

Who this is for: This kit is intended for Jeep Wrangler YJ owners (1987–1995) who have the 20‑gallon plastic fuel tank and need to replace deteriorated filler or vent hoses. It suits DIY mechanics and shops seeking an OEM‑style, ready‑to‑install replacement set (complete with clamps) to restore a secure fill and proper venting without fabricating adapters or hunting individual parts.
