Product Details

The Moeller 032518 is a permanent, below-deck marine fuel tank built from rotationally molded, cross-linked polyethylene — a construction method that enables complex shapes while delivering superior corrosion and pit resistance compared to traditional aluminum tanks. With its low-profile design measuring 36.5" L × 18.25" W × 7.25" H, this tank installs cleanly into tight below-deck spaces on a wide range of vessels.

All fittings are molded directly into the tank shell, including Hose Tite™ machined aluminum fill spouts, a 3/8" withdrawal fitting, and a vent fitting. The machined aluminum withdraw fitting features 360° rotational capability, making fuel line hook-up fast and convenient. All fittings meet E10 ethanol compliance requirements, ensuring long-term compatibility with modern gasoline blends.

Key Features:

  • Rotationally molded cross-linked polyethylene construction — corrosion and pit resistant
  • Hose Tite™ machined aluminum fill, withdraw, and vent fittings molded directly into shell
  • 3/8" machined aluminum withdraw fitting with 360° rotational capability
  • E10 ethanol-compliant fittings and materials
  • Suitable for gasoline or diesel use (diesel applications require Fuel Return Kit Part No. 035724-10, sold separately)
  • Hold-down grooves molded into tank shell — compatible with Moeller Tank Hold Down Kit (Part No. 035710 or 300110, sold separately)
  • Includes sender, pick-up, Fill Limit Vent Valve (FLVV), and Grade Vent Valve (GRV)
  • Conforms to all ABYC, NMMA, and U.S. Coast Guard regulations
  • Available with CE certification

The Moeller 032518 below-deck boat fuel tank is a reliable, regulation-compliant solution for permanent marine fuel storage, engineered to deliver lasting performance in demanding on-water environments.

I ordered on Sat. Dec 29th. With the new year holiday, I expected package to arrive on Wednesday. Was told it would arrive Thursday by the end of the day. I did not receive it until Friday afternoon.. In short, they shouldn't say 2 day delivery, since it took 6 days. I am however very happy with the product I ordered.
