ExtraFuelTanks OXP V1.8

This OXP adds buyable extra fuel tanks. These are primable equipment - 'Shift-n' to prime, and 'n' to activate. There are two types of tank available.

The Reserve Tank holds 1LY of Liquified Quirium Gas.

The Auxiliary Tank holds 3LY of Liquified Quirium Gas.

You may only fit one type of tank, so decide which will be the best for you. The 'Reserve' is an emergency top-up for when you are almost out of fuel. The 'Auxiliary' is much more of a game-changer allowing you to be much more flexible in terms of refuelling by docking or sunskimming.

You can buy a Full Tank (Cr 10 000 for the 'Reserve' and Cr 50 000 for the Auxiliary) from any TL10+ station. This will appear on the F5 screen as 'Reserve Fuel Tank' or 'Auxiliary Fuel Tank'. 

The fuel can be moved into the main tank when the main tank is empty. The F5 screen will then show the Reserve or Auxiliary tank to be 'Empty'.

After use you can refill the tank. 'Refill Reserve Tank' for Cr 10 or 'Refill Auxiliary Tank' for Cr 30. The tanks can be refilled at any Main Station.

If you have a Reserve Tank, you can upgrade to an Auxiliary Tank. The Reserve Tank must be empty, and the cost of the conversion is Cr 40 000. The new Auxiliary Tank will be full and ready for use.
