When to Replace
Replace this clamp if it's cracked, distorted, brittle, missing, or no longer grips the fuel hose securely. Inspect fuel-line clamps any time primer bulbs, connectors, hoses, or fuel fittings are replaced.
Installation Notes
Install over the correct fuel hose at the original factory connection point, making sure the hose is fully seated on the fitting before positioning the clamp. Inspect the hose for cracking, hardening, swelling, or abrasion while the connection is apart.
Technical FAQ
How many clamps come in this listing? This is sold as a pack of 4 clamps, matching the Mercury catalog quantity.
How do I know I have the right size? Match part number 41582T7 and confirm your fuel hose is approximately 5/16 in. (8 mm) ID before ordering, since similar nylon clamps come in other sizes.
Parts Desk Insights
This clamp pack is best used when servicing small-diameter fuel line on portable fuel tanks, primer bulbs, or outboard fuel connectors. The most common mistake is choosing a similar-looking nylon clamp by appearance instead of matching the exact part number and hose size, since Mercury uses several clamps that look nearly identical. For sizing, confirm your fuel hose is close to 5/16 in. (8 mm) ID before installing.
