I got the Walbro 255 pump, you have to modify the casing slightly on the holder but fits OK.
The emanage will take care of your fuel needs but here is a list of what I got in addition to the Greddy Kit:
1. Type S Greddy BOV (1 ea)
2. Greddy e01 boost controller (serves as 3 gages and program emanage)
3. Pressure harness to run emanage using boost instead of MAF
4. PLX Devices wideband 02 sensor to keep track of AF ratio
5. J&S Safeguard to retard timing
6. Parts to make fuel return system (hoses/FPR/modified rails)
7. Walbro 255 Fuel pump
The pump is probably not needed if you keep the stock setting on the kit as it will be rich as hell from Greddy and the fuel return system is not needed unless you want to boost higher than 8 pounds, I am installing it for future engine rebuild and higher boost.
