Abstract
A fuel supply system for an automotive vehicle having an internal combustion engine, comprises a fluid inlet line configured to receive fuel from a vehicle refueling station. A manifolded Y-connector includes an inlet port at an upper end of the Y-connector and in fluid communication with the fluid inlet line, an elliptical lower wall, a manifolded section extending from the inlet port to the elliptical lower wall, and a first and a second outlet port having substantially equal circular cross sections and each having a straight portion extending perpendicularly from the lower wall. A height of the manifolded section from the upper end to the lower wall is approximately four to five times a diameter of one of the outlet ports. The supply system further includes first and second fuel tanks fluidly connected to the first and second outlet ports of the manifolded Y-connector. Whereupon filling the fuel supply system, the manifolded Y-connector operates to deliver fuel to the first fuel tank first and to the second fuel tank second and accommodates any filling turbulence.
