a few electric fuel pump questions:
1) If you are installing an electric fuel pump in a chassis that originally just had an engine mounted mechanical pump----where the fuel lines run into the top of the fuel tank----this means that the electric pump is not gravity fed for a few inches but it is still pretty close to the tank. Is this generally ok and not a problem?
2) In cases where you are still using the stock mechanical pump but also using an electric pump (say for racing) and sometimes you don't use the electric pump---like driving on the street, is this ok for the electric pump? How does this work----does the electric pump just "freewheel" when not turned on? Like if you put a fan outside on a windy day but did not turn it on, i would imagine that the fan would still turn. Would this be harmful to the elec pump?
