Featuring a pre-calibrated fuel-level sending unit designed to work with the factory fuel gauge for this application is included. This module also features a HydraMat filter which has a unique internal reservoir that keeps fuel available at the pick-up and also provides protection from contaminates \n\nFuel pressure is internally regulated to 58 psi eliminating the added expense and effort of purchasing and installing an external fuel pressure regulator - no separate return line is required because this module returns excess fuel right inside the tank! This 1973-1987 GM C\/K Series Muscle Car EFI Fuel Pump module was designed as a direct replacement for your factory pick-up and sending unit. There is no need to purchase a custom EFI fuel tank. You can even retain the factory fuel hard line - just connect the outlet of the pump module to the hard line on your vehicle with EFI-rated fuel hose and hose clamps available in the Earls Vapor Guard line. This Muscle Car EFI Module includes a 350 LPH fuel pump and a Holley HydraMat. HydraMat is an amazing patent-pending fuel reservoir system that reduces fuel starvation issues that might otherwise occur while cornering, accelerating, stopping, traversing inclines, and during low fuel conditions.\u003cbr\u003e\u003cbr\u003eThis pump module is compatible with 1973-1986 fuel tanks that do not have the fuel injection baffles (GM11B style).\nIf you have the 1987 (GM11C) tank, you will have to use the earlier non-fuel injection tank.\n\nThe pump is not compatible for use with PWM (Pulse-width Modulation)\u003cbr\u003e\u003cbr\u003eDetails:\u003cul\u003e\n\u003cli\u003eApplication: 1955-1957 Chevrolet Coupe\/Sedan\u003c\/li\u003e\n\u003cli\u003eFree Flow LPH: 350\u003c\/li\u003e\n\u003cli\u003eFuel Sending Unit Ohms: 0-30 Ohms\u003c\/li\u003e\n\u003cli\u003eFuel Type: Gasoline\u003c\/li\u003e\n\u003cli\u003eInlet Diameter (in): 5\/16\"\u003c\/li\u003e\n\u003cli\u003eMaterial: Steel and Plastic\u003c\/li\u003e\n\u003cli\u003eVent Size: N\/A\u003c\/li\u003e\n\u003cli\u003eWarranty: Limited 90 Day\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003cbr\u003eLinks\u003cbr\u003e\u003ca href=\"https:\/\/www.holley.com\/\/documents.holley.com\/199r12275.pdf\/\"\u003eInstruction Sheet\u003c\/a\u003e","brand":"The Tuner Store","offers":[{"title":"Default Title","offer_id":44811654299734,"sku":"12-379","price":583.95,"currency_code":"USD","in_stock":false}],"url":"https:\/\/ezbuyco.com\/products\/holley-efi-fuel-tank-modules-350-lph-1955-1957-chevrolet-vehicles","provider":"EzBuyCo","version":"1.0","type":"link"}
