I know its a bit late in the day but just thought I'd let people know it can be done!
Just in the process of fitting an electric fuel pump to my 109.
Knocked up a bracket to mount an SU ( puller type pump ) in the engine bay, same type as fitted to the old Morris Minor, I chose this SU AUA66 pump as it's a puller pump and it's low pressure, only 1.5 PSI at the outlet of the pump so no fuel pressure regulator needed at the carb.
discard the original petrol lift pump and pipe to the carb, blank off the hole but also retain a water trap in the same position.
the pipe from the tank will screw into the water trap inlet and the outlet will rise up to the fuel pump inlet positioned on the bulkhead.........The outlet of the pump then routed round to the carb and job done bar the electric wiring........the pump has an earth tag and will need a Live from the ignition either wired through the oil light switch or via an Inertia switch which in case of a crash will cut off the electrics to the pump.
I opted for the simple set up and just wired it via the ignition switch just like the old Morris 1000, lets face it thats how they wired them back in the day, for me simple will do just fine.
This is the way I have done it not necessarily the only way or the best way, as we all know there are more than one way to skin a cat so you can do it your own way, I just thought I'd let people know that it's possible............the pictures were taken during the installation and after the wiring and pipe work was done.
