I got my walbro 255 off of ebay. One of those online ebay stores where you just buy it now. It is still the cheapest you'll find one.

I would be very cautious when upgrading your pump. You must be careful because upgrading the pump without upgrading the fuel rail and injectors can cause pressure drops in some injectors and cause lean conditions, even though your a/f ratio will not show this.

What kind of injectors are you using, and what kind of fuel pump is installed now? You may not need one at all as the GT pump is decent upto a certain point.

i'm in the process of a 5sfte project and i will be using the green top injectors and right now the stock fuel pump is in there right now.
