Feature:1. This 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.2. When 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.3. This 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.4. Using 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 9904 return style NBS (Silverado/Sierra) truck and other applications.5. This 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.Specification:Condition: 100% Brand NewItem Type: Fuel Pressure Regulator Filter Material: Aluminum AlloyColor: As picture shownInterchange Part Number: GF822, 10299146, 19239926, 33737Fitment: Fit for C5 Corvette 19992004Includes: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 Return.Package List:1 x Fuel Pressure Regulator Filter Note:1.
