Abstract
A control device 10 for isolating a fuel line 4 from its source 1 and its discharge 7 and preventing line 4 from getting vapor locked when its source 1 runs low or empty. The device combines a sensing device 2 at the fuel line intake and an activation device 3 for disabling fuel flow to a combustion engine at the other end. When fuel runs low or empty, the activation device 3 automatically isolates the fuel line from the reservoir 1 and the engine 7 to prevent the fuel line from further drawing down. Under this protection and upon refueling the reservoir, the fuel line has enough fuel to start back up without first having to re-prime the fuel line.
