XAT Racing 3UR Billet Fuel Rails 3URFE 3URFBE Fuel Rail Kit 1URFE
Now exclusively black anodized!
When we first began to modify and tune the mighty TOYOTA 3UR 5.7L v8 engine we dug into the areas that we could improve the performance and reliability of the engine. We all know that production equipment is made to work within stock performance parameters - so we knew that the fuel system would be the first place we would need to address. While the stock 3UR fuel rails do work just fine- when you start adding HP with a Supercharger or Turbo the fuel demand starts to exceed the flow capabilities of the stock fuel rails. Stock fuel rails are made from pressed and welded steel that have bent crossover and feed ports- these ports are as narrow as 5mm!! To put this measurement into perspective- each injector has a 6mm port on each rail- MEANING the feed port for all 4 injectors on each rail is smaller than just one of the injectors feed ports- WOW - so this is why Tundras approaching 600WHP start to run lean and drop pistons and start welding rings and breaking ring lands- the engine is going seriously lean under these high load situations- this is where we stepped in-
XAT Racing 3UR billet -8AN fuel rails are made from genuine RMR fuel rail stock- machined to perfection in a multi phase manufacturing process. We designed our fuel rail kit to exceed the performance of the stock rails when needed most- so we started with -8AN fuel rail stock- feed and drain ports are all -8AN ORB meaning you get a perfect o-ring seal on all inlets and outlets. Our injector standoffs have locating tabs so your injectors are facing the correct direction as TOYOTA designed- meaning your injector spray pattern is optimized- and not spraying in the wrong direction- this design feature is exclusive to the XAT Racing 3UR billet fuel rail kit. Injector standoffs have 14% larger (7.15mm) feed ports at the injector vs stock(6mm), while the rail inlet and outlet ports are a whopping 82% larger (9.15mm) than stock (5mm). All standoffs as well as inlet and outlet ports are e-85 safe o-ring sealed for a leak free design- this also means an easy replacement of o-rings if you ever need to refresh the setup. Mounting tabs are located in the same OEM locations and even use the OEM poly spacer and bolt for install- making install as easy as it can get.
XAT Racing 3UR billet fuel rail kit is offered in Anodized finishes as well if your looking to change up the color or look of the fuel rail setup-
Each kit comes with both fuel rails with all inlet and outlet ports in -8AN pre-installed as well as all standoffs installed.
