You just need to start with a few basic LabVIEW tutorials. Have a look at the learning resources listed at the top of the forum.

• You tank should connect to the current level wire, not an unassigned formula output.
• The cost should decline linearly, not exponentially
• You don't need any formula node (which also has syntax errors)! All the functions you need are in the numeric palette.
• You need to wire a reasonable loop time to the wait function
• You should wire the stop condition.
• Delivery should stop when you run out of money.
• Controls should have reasonable default values (zeroes are not reasonable).
• ... and please give your VI a reasonable file name. "Untitled 2.vi" is not a reasonable name!
• etc.

Here's a simple draft that drains the tank whenever the pump is on and the level greater zero.

You should be able to add your other requirements, such as money input and cost calculation. For example turn the pump off if you run out of money or run out of fluid.

This is intentionally just a picture. try to implement it and try to understand the reason for every single detail!

It is nowhere complete and just serves as proof of concept for part of your problem.
