SPE Motorsport 2020-2022 GT500 Fuel Rails blower pulleys This design reduces restrictions inSPE 2020 2022 GT500 Fuel Rails SPE is happy to introduce our new 2020 2022 Shelby GT500 mustang billet fuel rails. When trying to make more horsepower with the new GT500, be it with pump gas, race gas, or E85, the factory fuel rails become a bottleneck mainly due to the way the fuel is distributed to the rails. The feed hose tees in from the side and has to be distributed to two rails through a very inefficiently designed crossover fitting assembly.
