Abstract
A fluid flow control mechanism includes a crossover fuel assembly which controls fuel flow between tanks such that an engine fuel intake pipe remains submerged. It is for a work vehicle with a fuel system which has two tanks, three flexible couplings, a tube assembly and a valve assembly. The crossover fuel assembly includes a suction tube assembly, a check valve assembly, a connecting polymeric or elastomeric coupling and multiple clamping mechanisms. The engine fuel intake pipe fluidly connects the crossover fuel assembly to the engine.
