1. A refueling assembly of an engine comprising: an external housing;a door positioned within the external housing; anda flow guide positioned within the external housing and downstream of the door, the flow guide including an inlet in fluidic communication with the door; an outlet to flow fuel into a downstream filler pipe in fluidic communication with a fuel tank during a refueling operation; a nozzle seating section receiving a fuel nozzle during the refueling operation, the nozzle seating section including a planar surface which tapers in a downstream direction and is parallel to a central axis of the flow guide; and a contraction section positioned downstream of the planar surface,the flow guide further including an extension section having a substantially constant diameter positioned downstream of the contraction section. 2. The refueling assembly of claim 1, further comprising an additional door positioned upstream of the door. 3. The refueling assembly of claim 1, where the flow guide is coupled to an internal housing of the refueling assembly. 4. The refueling assembly of claim 1, further comprising a preloaded spring coupled to the door providing a return force to the door when opened. 5. A refueling assembly of an engine comprising: a nozzle stop actuator sized to allow a standard fuel nozzle to open a door, the door positioned downstream of the nozzle stop actuator; anda flow guide comprising a nozzle seating section positioned downstream of the nozzle stop actuator and including a planar surface which tapers in a downstream direction, the nozzle seating section receiving the fuel nozzle during a refueling operation; a contraction section positioned downstream of the nozzle seating section; and an extension section downstream of the contraction section that leads to an outlet of the flow guide into a downstream filler pipe, a central axis of the flow guide parallel to the planar surface of the nozzle seating section, the extension section having a substantially constant diameter. 6. The refueling assembly of claim 5, wherein an inner diameter of an outlet of the extension section is between 20 and 25 mm. 7. The refueling assembly of claim 5, wherein the nozzle stop actuator inhibits a non-standard size fuel nozzle from opening the door. 8. The refueling assembly of claim 5, further comprising an additional door upstream of the door that automatically closes without assistance from a refueling operator.
