This kit is compatible with all fuel types including popular alcohol mixtures such as E85. The OEM plastic spacers are reused to thermally insulate the fuel rail from the aluminum intake manifold. If building a custom fuel setup, appropriate fittings must be selected based on the specific application. Ample space around the fuel rail port(s) is necessary for larger accessories such as fuel pressure regulators, fuel pressure gauges, and fuel pulse dampers. To verify clearance, the dimensional drawings on the product pages can be used as a reference guide. Like the OEM fuel rails, the injector bores are 11mm ID so factory inj
