I totally agree with you on this one, Rob (BlueWasp) also runs smaller than 42's on a stock pump....36's I think, but farscape1a's post was for 42's on a 383. And given that he wants to use the 42's, then the 255gph is the way to go. I also need to point out that I didn't just pull 42's out of my Butt. I asked Jon before hand and with his calculator and my estimated FWHP, he told me that I should use 42's. Will uses 36's or something close to that and I told him that I think he's using injectors that are way too small for his setup. His reply was centered around the duty cycle of his injectors and felt that they were fine based off of his calc's and measurements.

The kit is actually a nice deal since the in tank harness they provide allows you to bolt it in. In addition they include the gasket, the o-ringed bolts that secure the filler neck to the tank, a new sock, etc.

Whats the part number for the 255gph pump? What should I expect to pay? Would this be a good upgrade for racing on a mostly stock engine?

I thought my racetronix kit came with instructions... but its been 2 years i cant be for sure. However you dont really need it. Connectors only plug into the appropriate spots and one end of the wiring harness goes to alternator. its really easy to install
