I have inherited a Plus 8, built in 1980 from my father.
The car wasn’t driven in the past five years.
Currently I am going to prepare the car.

Unfortunately I have not yet managed to provide the fuel pump with electricity.
If I give directly 12V electricity to the pump, it runs.
I suspect that the pump is switched via a relay. Is that right?

Where is this relay for the fuel pump?

For any help I would be grateful!
