Universal 5-Hole Sending Unit Gasket Kit – Moeller 03572810
A complete mounting hardware kit for installing a 5-hole flange fuel sending unit on a marine fuel tank. The kit includes a universal gasket, fine-thread screws, coarse-thread screws, and washers — covering both aluminum and fiberglass/plastic tank flange materials in a single package. Built to Moeller’s OEM specifications for a reliable, leak-free sending unit installation.
Best Use Case
Use this kit when installing or replacing a 5-hole flange fuel sending unit on a marine fuel tank. The universal gasket seals the sending unit to the tank flange, and the included fine and coarse screws ensure compatibility with the two most common tank flange materials — aluminum (fine thread) and fiberglass or plastic (coarse thread). This kit is the recommended mounting hardware for the Moeller Swingarm Electric Sending Unit Kit and is also compatible with most other 5-hole flange sending units including the Seachoice kits: 6–12", 6–24", and 6–27".
Key Features
- Universal 5-hole gasket — fits the most common marine fuel tank sending unit flange pattern
- Includes both fine-thread and coarse-thread screws — compatible with aluminum and fiberglass/plastic tank flanges
- Includes washers for a secure, sealed installation
- Complete kit — everything needed for a proper sending unit mounting
- Lightweight at 57g — compact hardware kit
⚠ Not for use in potable water systems.
Parts Desk Insights
The most important pre-sale check is confirming the customer’s tank has a 5-hole flange pattern — this is the most common pattern for marine fuel tanks, but some tanks use a different hole count or spacing. If the customer is installing the Moeller Swingarm Electric Sending Unit Kit, this gasket kit is the correct mounting hardware. The fine/coarse screw set is a key selling point — customers don’t need to know their tank material in advance, as both thread types are included. If the customer is replacing only the gasket (not the full hardware set), confirm the existing screws are in good condition before recommending this kit vs. a gasket-only option. For the complete sending unit system, see the Moeller Swingarm Electric Sending Unit Kit (4–28" Tank Depth).
