FAQ:

Q: What kind of oil tank fill cap do I Need?

A: When you need to replace your oil tank’s fill cap consider using the OEM 2 in. Locking Oil Fill Cap. This 2 in. female NPT locking is made of black iron.

Q: What is the purpose of a capping cap on a tank?

A: Caps are installed on adaptors when not in use to prevent gasoline vapors from escaping and to prevent water, dust and debris from entering the tank.

Q: Should I get rid of my underground oil tank?

A: The only way to eliminate the hazards that come with an underground oil tank is to remove the tank from your property. If you discover you have an abandoned tank on your property, it’s best to get rid of it. For those that use oil heat, this means replacing it with an above ground tank.

Q: Is there a buried oil tank in my yard?

A: Just because your home has converted to natural gas heat doesn’t mean that you’re risk-free, because there could be a buried oil tank somewhere in your yard. Hopefully, the tank has been properly decommissioned. If it hasn’t been, it’s considered “abandoned.”
