6. The apparatus in claim 1 wherein the fuel level detection system comprises:

a first caged floatball device mounted to said first end of said draw conduit whereby a first floatball in close proximity to said first end of said draw conduit acts as a flow restriction device;

a U-shaped conduit with a first end connected to said first end of said return conduit; and

a second caged float device connected to a second end of said U-shaped conduit whereby a second floatball in close proximity to said second end of said U-shaped conduit acts as a flow restriction device.

7. The apparatus in claim 6 wherein:

said U-shaped conduit is proximately close to a bottom of the tank.

8. The apparatus in claim 7 further comprising:

a weep hole in said U-shape conduit wherein said weep hole is proximately close to a bottom of said tank.

9. The apparatus in claim 1 wherein:

said draw restriction device is a valve.

10. The apparatus in claim 1 wherein:

said return restriction device is a valve.

11. An engine system having a circulating fuel supply system which balances fuel among multiple fuel storage containers comprising:

at least two tanks;

a draw conduit mounted to each said tank, and having a first end extending into said tank;

a pump adaptedly connected to a second end of said draw conduit;

a fuel consuming engine connected to said pump;

a return conduit mounted to each said tank and having a first end extending into each tank;

a second end of said return conduit adaptedly connected to said fuel consuming engine;

a shaft having a first end rotatably mounted to said draw conduit and extendable into said draw conduit;

a second end of said shaft rotatably mounted to said return conduit and extendable into said return conduit;

a float arm with a first end connected to said shaft;

a float connected to a second end of said float arm;

a draw butterfly valve mounted to said first end of said shaft; and

a return butterfly valve mounted to said second end of said shaft.

12. The apparatus in claim 11 further comprising:

a fuel level sending device which is mountable to said tank whereby a fuel level in said tank is monitored.

13. The apparatus in claim 11 wherein:

said draw butterfly valve is mounted on said shaft at a 90-degree angle relative to said return butterfly value when viewed from either end of said shaft; and

said float arm that is moveable through a 90 degree angle from a high fuel level position to a low fuel level position.

14. A vehicle comprising:

a chassis;

an fuel consuming engine mounted to said chassis;

a fuel pump mounted to said chassis and connected to said fuel consuming engine;

at least two tanks mounted to said chassis;

a draw conduit mounted to each said tank;

a first end of said draw conduit extending into each said tank;

a second end of said draw conduit connected to said fuel pump;

a return conduit mounted to each said tank;

a first end of said return conduit extending into each said tank;

a second end of said return conduit connected to said fuel rail of said engine;

a draw restriction device attached to said draw conduit;

a return restriction device attached to said return conduit; and

a fuel level detection system mounted inside each said tank for detection of a fuel level for use in the control of both said draw restriction device and said return restriction device.

15. The apparatus in claim 14 further comprising:

a fuel level sending device which is mountable to said tank whereby said fuel level in said tank is monitored.

16. The apparatus in claim 14 wherein:

said draw restriction device is a valve.

17. The apparatus in claim 14 wherein:

said return restriction device is a valve.

18. A method for balancing the fuel in a circulating fuel system with at least two tanks comprising:

drawing fuel from the at least two tanks to a fuel consumption system;

returning fuel to the at least two tunics from said fuel consumption system;

detecting a fuel level in each of the at least two tanks;

restricting a flow of fuel returned to each of the at least two tanks based on said fuel level; and

restricting a flow of fuel drawn from each of the at least two tanks based on paid fuel level.

19. The method in claim 18 further comprising:

comparing said fuel levels in at least two tanks whereby a differential fuel level is determined;

restricting a flow of fuel returned to each of the at least two tanks based on said differential fuel level; and

restricting a flow of fuel drawn from each of the at least two tanks based on said differential fuel level.
