Damo is right, its dead easy to do that way, for road use though i would advise putting fuseible link between ecu and your live feed, 40A should be ok. Also, you will need the larger diameter fuel line from the k11, use the original feed pipe as your return pipe then. External pump certainly the easiest option, just remember to put it well out of the way and isolate it from the body... i.e, in a bracket with some kind of rubber mount....helps stop sharp shocks from damaging it.
