Features: 1This filter/regulator assembly is commonly used when adapting return style fuel systems for use with returnless applications. Popular for simplifying the fuel system for LS swaps or standalone EFI systems such as for Holley, for FiTech, or for FAST designed to operate on 58psi of static supply pressure. 2When mounted near the fuel tank this filter allows you to run a single fuel feed line to the engine and just a short return loop back to the tank. 3This is the correct filter/regulator required for LS Swaps using returnless style fuel rails and also popular when doing popular the TBSS/NNBS Gen IV intake manifold swap. 4Using this filter/regulator between the returnless style fuel rails and your return style fuel lines allows for a plug and play style conversion for retrofitting TBSS/NNBS intake manifolds onto 99?04 return style NBS (Silverado/Sierra) truck and other applications. 5This fuel filter features an internal bypass that regulates fuel output pressure to 58psi. The filter features a 3/8 male inlet, 5/16 male return outlet, and a 3/8 female supply outlet. This fitting combination makes for simple plumbing of fuel systems for LS Swaps and aftermarket EFI conversions.Condition: 100% NewItem Type: Fuel Pressure Regulator Filter Material: Aluminum AlloyColor: As picture shownInterchange Part Number: GF822, 10299146, 19239926, 33737Fitment: Fit for C5 Corvette 1999?2004Includes:Fit for C5 Corvette Fuel Filter/Fuel Pressure Regulator assemblyRed Horse Performance ?6AN Conversion Fitting for OuletRed Horse Performance ?6AN Conversion Fitting for InletRed Horse Performance ?6AN Conversion Fitting for ReturnPackage Included:1 x Fuel Pressure Regulator Filter
