Hi,

I have 3 relays in a row under the bulkhead wiring loom cover but don't know out of the 3 which one it is.

Does anyone know which one it is?

Thanks,

Bhups

Assume it's an M52?

See page 1210.17-04 and check the colours & number the wires going to each of the relays.

Says on there fuel pump relay has 4 connections; wires of the following colours:
Red
Red/white
Green/violet
Brown/green

The red and green/violet wires will be thicker than the other two. Find the relay with those connections and that's your fuel pump relay :) provided the wiring hasn't been hacked about too much.
