No Granatelli, go Racetronix. For a long time there was only one company making the 255lph pumps and it was Walbro but more recently it seems a chinese company has started making some cheap.

I say go Racetronix because the kit will fit better than any other, is a Walbro pump very much like all the others but the details make it worth it. Go with the wiring upgrade too, for the price you can not build anything half as nice.

I tried using a higher volume GM pump and a DIY wiring upgrade and ended up buying the Racetronix kit later anyway.

The wiring upgrade makes sure the pump gets adeuate voltage. Cars are run with pretty much the bare minimum wiring sizes and a higher capacity pump will draw a little more power.
