2008-2020 Subaru STI Fuel System Package by COBB Tuning
The COBB Subaru Fuel Rails are constructed of 6061 Billet Aluminum and feature black anodizing with a laser etched COBB logo. Each rail comes with -8 AN to -6 AN adapters pre-installed. All lines are pre-assembled with double-swivel sport crimp style hose ends and ready for installation. Stainless reinforced PTFE line with black covering has a 3" minimum bend radius which allows for a straight forward installation when used as intended. With a 2500psi operating pressure and >10000psi burst pressure, these lines are incredibly robust. Also includes a COBB fuel pressure regulator.
The COBB 1050x Fuel Injectors provide increased fuel flow while maintaining stock idle and driveability with proper tuning. Corrosion resistant internals make them compatible with all known fuels, capable of extended service life with corrosive fuels. Replaceable inlet filter extends service life. AEM's 320lph E85-Compatible High Flow In-Tank Fuel Pumps feature robust internal construction that is designed to withstand the low lubricity characteristics of ethanol and methanol fuels, and are tested to work with ethanol fuels up to E100, methanol fuels up to M100 and all types of gasoline. Its compact, short body design (65mm length) with mounting hooks also makes it ideal in universal applications that have fuel tanks with tight tolerances. The 320lph E85-Compatible High Flow In-Tank fuel pump includes a wiring harness, pre filter and O-rings.

COBB Manufacturer's Warranty
The products are all very high quality and go together well. The process is long and there is a lot to do, but the instructions are very clear. They give you before and after pics of every connection and good tips. Unfortunately, they did not cover several things that my 2014 STi had. My car had OEM steel brackets bolted to the heads covering both fuel rails. The instructions made no reference to this at all. It was a major procedure that was not one of the steps. It required the removal of a high pressure oil line that uses copper washers, which obviously aren't included and I didn't have. Couldn't start the engine without them. I eventually had to go to the Subaru dealer and work with the parts guy to figure out which part it is (part of the variable cams) and buy new copper washers. They were only 2 bucks but still an unexpected major pain that left me unable to even start the car after this major install. Also didn't cover the removal of the air pump. Again, very easy, but the instructions made no mention of this process and it is a necessary step. I assumed from the very detailed instructions that I missed something - "surely they wouldn't just leave this part out... right?" The majority of the instructions are very precise and help a lot, which is why the left out steps were confusing.
