conversion fuel pump

[Stuart]

I've got a 1303 super with a standard 1600 fuel injection engine. I've bought a normal aspirated engine and are in the process of fitting it in my bug. The problem is that i need to swap the original injection fuel pump for a "normal" electrical fuel pump as the injection fuel pump gives a way to high pressure! Does somebothy know how i connect the pump because the original fuel injection pump is wired over the injection computer and some relays in the back. Every help welcome!!!!
