I spoke with a few performance shops and they said they really don't rewire pumps unless they are asked to do so by the owner. Boosted cars ran fine with stock wiring.
I had Walbro 255 and now have FullBlown 340. Both worked fine. Is this mod REALLY necessary?? I am sure pump performance will be "better" with more voltage but do we REALLY need to do this?
Just asking.

DEPENDS.
I've got a 255 as well, it'll be running me short on fuel soon no doubt, by wiring it directly you can get a substantial increase in fuel out of it since it was designed to work at higher voltage than it currently is. Generally though the gains aren't insane so probably going to a larger or dual pump is the next move but if someone wanted jut a little more out of or wanted to get rid of the whine sound that commonly works.
Bottom line is it IS a superior and the "proper" way to wire the pump in this case since that's the voltage it was designed for.
