Whether you are replacing an old tank or setting up a new boat, the right fuel tank depends on how far you go, how much space you have, and what outboard you run. Here is a simple guide to choosing a boat fuel tank in New Zealand, using the Moeller, Scepter and Easterner tanks we stock in Auckland.
Quick answer
- Portable tanks are easy to take off the boat and fill at the service station. Great for small and medium outboards.
- Underfloor (fixed) tanks give more range and free up deck space, but must fit the space under your floor.
- Make sure the tank fitting matches your outboard’s fuel line connector, or buy the right fitting.
- Fit a water separating fuel filter to protect your engine.
Portable boat fuel tanks
Portable tanks sit on the deck or in a well and connect to the outboard with a fuel line and primer bulb. They are simple and handy, and many owners carry two so one can be filled while the other is in use. We stock Moeller 45 litre portable tanks, Scepter portable tanks and Easterner tanks with a gauge.
Underfloor fuel tanks
Underfloor tanks are fitted under the deck and filled through a deck filler. They hold more fuel and keep the deck clear. Measure the space carefully, including height, and allow for the fittings and hoses. See Moeller underfloor tanks, plus Perko deck fillers and anti-siphon valves.
How big a fuel tank do I need?
Work out your engine’s fuel use at your normal cruising speed, multiply by the hours you usually run, and then add a good reserve. A common rule on the water is to use a third of your fuel going out, a third coming back, and keep a third in reserve. If your trips are long or you head offshore, go for more capacity or carry a second tank.
Fuel fittings for your outboard
Yamaha, Mercury, Honda, Suzuki, Tohatsu and older Johnson/Evinrude engines use different fuel line connectors. The fitting on the tank and the one on your fuel line must match. We stock fittings for each brand, including Yamaha, Suzuki, Tohatsu and Honda and Johnson/Evinrude, plus fuel hose assemblies and primer bulbs.
Spare parts and gauges
Most tank problems are small parts: a cracked cap, a worn vent or a faulty gauge. See fuel tank spare parts and Moeller tank level senders and gauges.
