How long do plastic gas tanks last on boats?

How long do plastic gas tanks last on boats?

Workers at Tiara Yachts install a plastic fuel tank in a new 38 LS. Luckily, it’s a choice most boat owners won’t have to make, unless they keep their boat for a long time, or decide to buy and rehab an older vessel. Most fuel tanks last for 15 years, maybe 20, if properly installed and maintained.

What material are boat fuel tanks made of?

There are 4 main materials that are used for marine fuels tanks; polyethylene, aluminum, fiberglass, and stainless steel, of which the latter two are not as common so I am directing this article to polyethylene marine fuel tanks and aluminum marine fuel tanks.

Do aluminum fuel tanks corrode?

Aluminum tanks can be affected by pitting, crevice and galvanic corrosion. 55% of these problems involved removing permanent structures to access below deck fuel tanks. The repairs ranged any where from a few hours to several months. 92% of reported failures were due to corrosion.

Is aluminum good for fuel tanks?

All things considered, the recommended fuel tank material is 5052, either 1/4 or 1/2 hard aluminum.

Does gasoline eat through aluminum?

Gasoline fuel is not conductive, but the presence of ethanol or ethanol and water will conduct electricity. The galvanic process that occurs to aluminum trim tabs, stern drives, shaft couplings, etc. will occur within the aluminum fuel tank.

Will gasoline dissolve fiberglass?

yes, gasoline or any minerial based product (even paint; paint thinner) will swell the fiberglass. But covering the “glass” in a gel coat, or high end body filler, and painting it with an epoxy primer first… you should have no problems.

Can you put gas in an aluminum tank?

Can I use your refueling tanks for gasoline legally? Yes, we manufacture our aluminum refueling tanks to meet and exceed the requirements for gasoline, kerosene, methanol, and diesel. In fact, many government agencies are currently using our aluminum refueling tanks.

Does diesel fuel corrode aluminum?

Fazal et al. (2010) did an assessment of aluminum (99% commercially pure) corrosion in diesel and palm biodiesel by static immersion was performed. Aluminum experienced higher pitting corrosion in biodiesel than that in diesel.

Can you use Aluminium for fuel tank?

All things considered, the recommended fuel tank material is 5052, either 1/4 or 1/2 hard aluminum. The 5052H32 designation is for the 1/4 hard, and the 5052H34 designation is for the 1/2 hard aluminum. The 5052H32 aluminum is very easy to form and is readily available from homebuilt suppliers.

How long do fiberglass oil tanks last?

Oil Tank Lifespan While typical industry standard for an inside tank is 15 years and an outside tank is 10, it is critical you do not wait until that age to start thinking about a regular inspection.

Is plastics or aluminum better for boat fuel?

Plastic is probably more common than aluminum at this point, and changes in boat fuel may mean long term changes in which is best for you and your boat, but for now we think it’s fair to say that there are no losers here. Choose either and you’re likely to walk away a happy boater.

Should I Choose an aluminum or polyethylene fuel tank?

Whilst it is soft for a metal, aluminum is still far more resistant to damage, and crucially leaks, than polyethylene. Where plastic might crack on impact, aluminum is far more likely to bend or dent. Whilst a dented tank is certainly irritating, crucially it isn’t going to be as damaging as a tank that leaks all over your boat.

Do you need a metal fuel tank for your boat?

Should you ever find yourself in the unfortunate position of your boat catching fire then aluminum, or metal fuel tanks of any kind aren’t the best option to have fitted. While plastic is a heat insulator, metal conducts heat and therefore the risk of exploding diesel fuel becomes a very real and dangerous possibility.

Why choose a HDPE fuel tank for your boat?

In the event of a fire onboard your boat, HDPE tanks will buy you a little more time than aluminium tanks because the plastic is a heat insulator rather than a heat conductor. Whilst the tank will still ultimately melt and expose the fuel to the fire, the fuel is less likely to explode in this scenario.
