A recent thread got me to thinking. I understand having the power removed to the fuel pump would cause the engine to turn off on a fuel injected engine, but carbs, I think, would be a different matter. On the fuel injection engine when the fuel pump shuts down, the fuel pressure goes to zero very fast as there is no reservoir to keep pressure steady. With carbs, the engine would continue to run until the fuel level in the float bowl gets too low. Wondering how long that would be and would that be long enough for engine damage to occur?
Don't newer cars have several reasons for the fuel pump to shut off for safety reasons? Crash, low oil pressure, over temp??? Tom |
