This is a complete top feed fuel system upgrade:
1 ATS Top Feed Fuel Rail Kit (Gen2 or Gen3)
1 set of four top feed injectors
1 fuel feed line with filter adapter - plug-n-play to our rail no cutting hoses/installing fittings
1 ATS FPR adapter - use your oem FPR with our rail - this part alone saves your over $200 in buying/making lines/fittings, etc. We have tested this at 550whp.
4 feet of 1/4 fuel return hose
2 feet of 1/8 vacuum hose for FPR
4 injector connectors - PNP wiring upgrade available as well
1 GENUINE (I can't stress this enough) Walbro fuel pump
This is our go-to 500+whp fuel parts in one easy combo.
UPDATE 8/25/2015 - added additional injector options for combo kit
