Quick Answer: How To Make A Motorcycle Gas Tank Fiberglass

Can a fuel tank be made of fiberglass?

There is no prohibition on fiberglass for gasoline tanks. But they do, as you said, have to be done right. The unfortunate thing is in the past many people used plain old polyester resins which do not play well with gasoline.

Will fiberglass hold gasoline?

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.

Is polyester resin gasoline resistant?

Polyester resins, gel coats and fillers commonly incorporate phthalates. Since they are in solution, the phthalates and the other heavy dissolved molecules are able to pass through the fuel line filters.

Will gasoline eat through fiberglass resin?

Fiberglass will definitely withstand gas, but that will not be your problem. Because you can’t get in and super-clean the rust the fiberglass will most likely fail to adhere 100%, ‘missing’ just a bit here & there.

Can you JB weld a gas tank?

What you need for a wet repair is JB Weld Autoweld or SteelStik epoxy putty stick. Once cured, the epoxy can withstand 300-degrees and 900 psi of pressure, so it will be perfect for your leaky gas tank. This is the fastest way to keep that expensive fuel in the tank and not on the asphalt.

Is epoxy resin gasoline resistant?

Gasoline Resistant Epoxy- MAX GRE Resin for Coating, Bonding, Potting, Fiberglassing Reinforcement & Repair – Resistant to E85 Gasoline & Diesel Fuel.

Does ethanol eat fiberglass?

The ethanol slowly dissolves resin in older fiberglass tanks. This dissolved resin deposits itself on intake valves, and then the intake valves stick and that causes engine damage. There have been several reports of gas tanks that started to leak because they were weakened by ethanol.

Is fiberglass oil resistant?

Fiberglass rose into prominence in the 1960s when oil refineries started using it for storing crude oil and petroleum. According to tank manufacturers, fiberglass tanks are just as strong as steel tanks and are resistant to rust and corrosion.

What metal are motorcycle gas tanks made of?

The gas tank can be made out of plastic high-density polyethylene, which can be made into complex shapes, save space, and can improve crash safety. The gas tank can also be made out of steel or aluminum, which is welded from stamped sheets.

What gauge steel is a motorcycle tank?

This course uses 20-gauge steel for ease of use. The Canadian DOT standard for a motorcycle gas tank is 16-gauge (the lower the number, the thicker it is and therefore harder to work with).

How thick is a fuel tank?

The HDPE structural layers are typically in the thickness range 0.1 in. to 0.2 in. (2.5 to 5 mm), and the EVOH barrier layer is typically 0.004 in. to 0.012 in. (0.1 to 0.3 mm). Tank manufacturers need to measure both the thickness and the depth of the barrier layer.

Is 2 part epoxy gas resistant?

Loctite® Epoxy Weld Bonding Compound is a two-part system consisting of an epoxy resin and a hardener. Loctite® Epoxy Weld does not shrink and is resistant to most shop fluids such as water, diesel fuel, gasoline, antifreeze, hydraulic fluid, motor oil and transmission fluids.

Is Bondo gas resistant?

Bondo is resistant to fuel, but only after it is cured. If you are smoothing out a gas tank, that is great, it you are trying to fix a rusted out gas tank, this is not going to do a good job.

Is fiberglass resistant to petrol?

Fibreglas is NOT impervious to petrol.. It soaks along the miniscule cracks.. and underseal is dissolved by petrol.

What JB Weld is fuel resistant?

When fully cured, J-B Weld is completely resistant to water, gasoline, and about every other petroleum product or automotive chemical. For wet-surface or submerged water or gasoline repairs, try our SteelStik or WaterWeld. KwikWeld is a great alternative to original J-B Weld when you need a quick-setting epoxy.

Will Super Glue work with gasoline?

Superglue does dissolve in petrol, so don’t bother with cyanoacrylates.

Can flex seal be used on a gas tank?

No, Flex Seal is not resistant against a corrosive flammable like gas or oil. It is strongly recommended that you do not attempt to use Flex Seal Liquid™ on a gas tank. Don’t be deceived by the fact that it may not ignite or leak through right away.

Will Gorilla Glue work on gas tank?

Gorilla Glue is a polyurethane based glue, which is what gives it its fantastic gluing abilities. Petroleum products can dissolve polyurethane based glues, so I highly advise you to replace your fuel pump over gunking up the entire thing with gorilla glue.

Can you weld a metal gas tank?

The process of welding gas or diesel tanks can be extremely dangerous. There is the possibility of igniting fuel vapors, and if the welder is using the welding process of MIG or TIG inside a fuel storage tank, they are in danger of suffocating from fumes if argon gas is used.

How do you fix a pinhole in a motorcycle gas tank?

Repair the holes in the tank with the epoxy. Pour the epoxy into the tank’s fuel fill hole. Immediately cover the hole with plastic wrap secured with a rubber band around the mouth. Swill the epoxy around the tank for two minutes to allow it to cover and fill any cracks or holes.

What sealant works with gasoline?

Permatex PermaShield Fuel Resistant Gasket Dressing and Sealant is a polyester urethane sealant with strong resistance to gasoline and all other automotive fluids, making it excellent for a variety of applications, including oil pans, axle assemblies and fuel injectors.
