Product Details

The Moeller 32512 is a 12-gallon permanent below-deck marine fuel tank built from rotationally molded, cross-linked polyethylene — a superior alternative to conventional aluminum tanks. Engineered for reliable, long-term installation aboard gasoline or diesel-powered boats, this tank is a trusted choice among quality boat builders and serious boaters alike.

Key Features:

  • Cross-linked polyethylene construction — provides excellent corrosion and pit resistance, and allows for complex shape designs not possible with aluminum tanks
  • Ethanol & biodiesel compliant — safe for use with modern fuel blends
  • Machined aluminum 3/8" withdraw fitting with 360° rotational capability for easy and flexible hook-up
  • 1-1/2" diameter fill spout with Hose Tite™ fittings; fill, withdraw, and vent fittings molded directly into the tank shell
  • Integrated electrical sending unit compatible with industry-standard 33–240 Ohm dash-mounted fuel gauges
  • Hold-down grooves molded directly into the shell — compatible with Moeller Tank Cradle Hold Down Kit (Part No. 035710 or 300110, sold separately)
  • UV rating of 8 — temperature rated from -40°F to 176°F
  • Meets all ABYC, NMMA, and U.S. Coast Guard regulations; CE certification available
  • ABYC-compliant fittings with seamless connections to low-perm hoses

Tank Specifications:

  • Capacity: 12 gallons (45 liters)
  • Dimensions: 24.50" L x 18.50" W x 7.25" H (add 2-1/8" to height to accommodate fill spout height)

Note: Due to Moeller production changes, below-deck tanks may be shipped with molded polyethylene fuel fills in lieu of aluminum fuel fills. For diesel applications, a return kit (Part No. 035724-10) is recommended. Compatible installation kit: Part No. 035723 (sold separately).

Competitive pricing

Easy to order and nice to know inventory quantity availability.

Love them!!! They send E-Mail conformation when order is placed and tracking number when shiped.

Great price! Can't wait to see how the rest of the transaction goes.

Rather amazing and uneventful service in this day and age. Ordered a Thule bike rack for my Nissan Murano. It was in stock (unusual for high-end specialty products), shipped the next day, and was on my doorstep in a few days (excellent for a 60 lb. large box). I'd buy anything from these people without any reservation. AND, your order is insured - completely superfluous. Oh, and did I mention, the lowest price I could find ANYWHERE, and not by a few dollars - a lot.

Phone service was quick and personable wanting to solve my problem immediately. The weight of my package was wrong causing shipping to be $300 to ship a gas can but was fixed right away. Prices were great! I would purchase through them again!
