Default intank fuel pump conversion

I am installing a 1982 fuel sending unit with a electric fuel pump .
I have a 1979 coupe (carburated)
can I cross a wire from the fuel gage sender to the + terminal of the fuel pump
to power the fuel pump.

fyi: i want the car to start easier.
a filter and regulator will be install on the chassy somewhere.

thanks

You cannot power the pump with the wiring from the gauge.

You will need proper fuel pump wiring--including the ground. I strongly suggest an oil pressure safety switch if not an oem-style fuel pump relay so the pump doesn't continue to run if the engine dies. (like if you're in a collision, and there's a fire--you don't want the pump to continue running if you're unconsious. Hopefully the collision will stall the engine, which eliminates oil pressure, which kills the electric pump.

Some folks--including Ford--add an inertia switch to disable the fuel pump in a collision.

Thanks
The grd wire is there.
I will check the fuse / relay boxes for a fuel pump relay hook up
The electric pump was an opp in 1979 , so maybe I will get lucky.
Thanks again
