Question: A fuel pump is a frequently (but not always) essential component on a car or other internal combustion engined device. Many engines (older motorcycle engines in particular) do not require any fuel pump at all, requiring only gravity to feed fuel from the fuel tank or under high pressure to the fuel injection system. Often, carbureted engines use low pressure mechanical pumps that are mounted outside the fuel tank, whereas fuel injected engines often use electric fuel pumps that are mounted inside the fuel tank (and some fuel injected engines have two fuel pumps: one low pressure/high volume supply pump in the tank and one high pressure/low volume pump on or near the engine). Fuel pressure needs to be within certain specifications for the engine to run correctly. If the fuel pressure is too high, the engine will run rough and rich, not combusting all of the fuel being pumped making the engine inefficient and a pollutant. If the pressure is too low, the engine may run lean, misfire, or stall. does a carbureted engine have a fuel pump

Answer: yes

Question: Fans would only have to wait another year for Cowboys--Steelers III in the Super Bowl, as both teams advanced to Super Bowl XXX. Like the previous two matchups, the game was close, but this time favored the Cowboys, who won 27--17 after Steelers quarterback Neil O'Donnell threw two interceptions to Cowboys cornerback Larry Brown, who would be named Super Bowl MVP for his efforts. have the cowboys ever beat the steelers in a superbowl

Answer: yes

Question: Any function induces a surjection by restricting its codomain to its range. Every surjective function has a right inverse, and every function with a right inverse is necessarily a surjection. The composite of surjective functions is always surjective. Any function can be decomposed into a surjection and an injection. is the inverse of a function always surjective

Answer:
yes
