F-BIRD'88 Remove the in tank EFI pump and use this pump on TBI to carb conversion.

against all odds But how does it work when the pump is not turned on? Would this be a restriction in the line somehow?

a) What about TBI to carb conversions? Can we leave the stock electric pump in the tank?

F-BIRD'88 As long as the electric pump is mounted at the back near the fuel tank and mounted level or slightly below or slightly above the fuel level it will work like a charm.

Electric fuel pumps do have ability to "draw" fuel in on the inlet side.

A Carter P4070 makes for a very good axillary "pusher pump" to add onto a performance car with a engine mounted mechanical fuel pump.
The carter pump ensures the mechanical pump does not vapour lock and
sees a steady fuel supply.
You can drive with the electric pump off and switch it on when needed. You can even control it with a WOT "nitrous switch", on the carb,, controlled thru a relay.

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?
