Overview
The Crown Automotive 52040079 is a fuel filler hose for a 20 gallon tank, with a 1-1/8” inside diameter on its flared side and a 15/16” or 1” connection on the other side. It is a replacement fuel filler hose from a brand that builds its catalog around Jeep replacement parts.
Measure the ends of your existing filler hose and compare them with the diameters above before fitting. Confirm fit for your vehicle’s year, model and trim before ordering.
Key features
- Designed for a 20 gallon tank
- 1-1/8” inside diameter on the flared end
- 15/16” or 1” on the opposite end
- Replacement fuel filler hose from Crown Automotive
Choosing matching hose ends
Filler hose ends have to seal against both the filler neck and the tank nipple, so matching the diameter on each side matters more than overall length. A flared end usually seats over a tapered neck, while a smaller end often slides onto a fitting. Mixing up the two ends is a common reason a new hose leaks at the first fill.
Before buying, measure the old hose ends with calipers or a tape across the outside of each opening, and note whether one side is flared. Compare those numbers with the sizes shown above. If the old hose was replaced at some point, its ends may already differ from the original, so measure rather than assume.
- Measure both ends, not just one
- Note which end is flared
- Check clamp size for each end
- Inspect the filler neck for dents before fitting
