I'm going to do mine, once I fit the Walbro
This can be done on anything that you want to supply more current to. The coil is another good contender, I used to wire up the headlights of my cars this way too (because I was fitting illegal 150w bulbs !) you would be amazed how much current loss you get through the standard wiring. My air-con pump clutch is also wired through a relay as the existing current wasn't enough to kick in the tired clutch.

the fuel pump drops voltage once its under load and can run cars lean etc , the fuel pump mod just keeps the pump workin as it should
tim williams does a nice kit for them
cheers
you shouldn't need a kit, its just a relay you can pick from anywhere
but yal need a decent cable from the battety m8
I looked into this when i had my 850.
I done a few runs on full boost and i only saw a .3 drop so i dont think its a must mod unless you see that theres a big enough drop from battery to pump.
