Question about wiring in an electric fuel pump
Its time to put in my fuel pump in my GLC 12a conversion. I have a couple of questions...
My car is running a stock nikki carb and stock rx7 fuel pump
1. Can I just pick a circuit that is "hot " with the key on and wire in my pump or do I run a whole separate circuit with its own fuse and relay?
2. Is it ok to mount the pump in the engine bay or does it need to be near the tank?
The car originally had a mechanical fuel pump so there is no existing circuit to use already. Thanks for any help in advance

I'd run a fused power wire through a relay. Use a wire that is powered as the trigger for the relay. For example, on an FC, power comes through a 15A fuse in the interior fuse box, and is directed to the pump by the circuit opening relay.
For placement, search around to see if anyone mounts them in the engine bay. OEM placement is always at the tank as far as I know.

If you do wire the fuel pump through a relay that is powered anytime the key is on, make sure to include a tipover/inertia switch in the circuit so that if the car ends up in a collision the fuel pump cuts out.
