a cylindrical tank that includes a first end and an opposing second end;
the cylindrical tank is housed within the frame that such that axis of the cylindrical tank is oriented generally perpendicular to the frame rail of the vehicle; and
the cylindrical tank is supported by a portion of the first driver side tank support and a portion of the first passenger side tank support.
2. The fuel system of claim 1 , further comprising a manifold that is in fluid communication with the cylindrical tank.
3. The fuel system of claim 2 , further comprising the manifold assembly is configured to be attached to a portion of the frame.
4. The fuel system of claim 2 , the manifold assembly includes at least one of a fill receptacle, a high pressure gauge, a low pressure gauge, or an outlet port.
5. The fuel system of claim 4 , wherein the fill receptacle is in fluid communication with a valve assembly in which the valve assembly is in fluid communication with the cylindrical tank.
6. The fuel system of claim 4 , wherein the outlet port is in fluid communication with an engine of the vehicle.
7. The fuel system of claim 1 , further comprising a filter that filters a content of the cylindrical tank prior to delivery to an engine of the vehicle.
8. The fuel system of claim 1 , further comprising a regulator that controls a portion of flow of the content delivered to an engine of the vehicle.
9. The fuel system of claim 1 , further comprising:
a portion of the first end of the cylindrical tank is supported by the driver side tank support; and
a portion of the second end of the cylindrical tank is supported by the passenger side tank support.
10. The fuel system of claim 1 , further comprising one or more panels to cover the frame.
11. The fuel system of claim 10 , further comprising an access panel that provides access to a manifold assembly and the manifold assembly is located inside the one or more panels.
12. A fuel system, comprising:
a frame that is configured to be attached to a first frame rail and a second frame rail of a vehicle such that the frame is positioned above the first frame rail and the second frame rail of the vehicle and behind a cabin of the vehicle, the frame includes a driver side pair of vertical brackets, a passenger side pair of vertical brackets, a first driver side tank support attached between the driver side pair of vertical brackets, a first passenger side tank support attached between the passenger side pair of vertical brackets;
two or more cylindrical tanks, wherein the two or more cylindrical tanks each include a first end and an opposing second end;
a manifold assembly in fluid communication with at least one of the two or more cylindrical tanks;
the two or more cylindrical tanks are housed within the frame that such that axis of the two or more cylindrical tanks are oriented generally perpendicular to the frame rail of the vehicle;
the two or more cylindrical tanks are supported by a portion of the first driver side tank support and a portion of the first passenger side tank support; and
one or more cross members that structurally support the first frame rail and the second frame rail.
13. The fuel system of claim 12 , further comprising a filter and a regulator that are each mounted on or within the frame, wherein the filter is configured to filter gas from the plurality of tanks, the regulator is configured to be in fluid communication with the filter.
14. The fuel system of claim 13 , further comprising an inlet configured to receive a fueling nozzle and be in fluid communication with the plurality of tanks.
15. The fuel system of claim 12 , further comprising the manifold assembly includes at least one of a fill receptacle, a high pressure gauge, a low pressure gauge, or an outlet port.
16. The fuel system of claim 12 , wherein the vehicle is a truck.
17. The fuel system of claim 12 , further comprising a housing that covers the two or more cylindrical tanks within the frame.
18. The fuel system of claim 17 , the housing further comprises at least one of a cap, a rear panel, a front panel, or a side panel.
19. The fuel system of claim 17 , the housing further comprises one or more access panels.
20. The fuel system of claim 19 , further comprising:
the manifold assembly includes at least one of a fill receptacle, a high pressure gauge, a low pressure gauge, or an outlet port; and
the one or more access panels provide access to at least one of the fill receptacle, the high pressure gauge, the low pressure gauge, or the outlet port.
