The Full Function 13B-RE Rail Set is engineered for enthusiasts seeking to upgrade their fuel system for high horsepower applications. This set includes both primary and secondary fuel rails, featuring a substantial 1/2″ bore to accommodate increased fuel flow requirements. Installation and reliability are enhanced by several key design elements. The rails utilize O-ringed end fittings, eliminating the common issues associated with Teflon tape or damaged threads. Centering spacers are provided to guarantee precise injector alignment, which is critical for preventing air and fuel leaks. Furthermore, the set comes complete with high-strength, corrosion-resistant stainless steel hardware. This fuel rail set is specifically designed to fit the 90-95 Mazda Eunos Cosmo equipped with the 13B-RE engine. It is compatible with various Injector Dynamics injector models, including the ID1050XDS, ID1300XDS, ID1750XDS, and ID2600XDS for both primary and secondary applications. The product page notes that injectors purchased with the rail will be supplied with their corresponding lower inserts.
