300LPH External Inline Fuel Pump Kit for 12V EFI Systems<\/h2>\n
Weak fuel delivery, pressure drop under load, and mismatched plumbing parts can delay an EFI build or make troubleshooting harder. This 300LPH fuel pump kit<\/strong> combines a 300LPH external inline fuel pump<\/strong>, adjustable 20\u2013120 PSI regulator, 100-micron pre-filter, 10-micron post-filter, 25FT aluminum fuel line, mounting bracket, and connection adapters. It is intended for custom 12\u201313.5V EFI installations where the pump, filters, regulator, line routing, and vehicle connections have been verified before installation.<\/p>\n

Complete custom-install EFI fuel delivery package; confirm all vehicle-side connections and electrical components before ordering.<\/figcaption><\/figure>\n What Comes in the 300LPH Fuel Pump Kit?<\/h2>\n
- \n
- \n300LPH External Inline Fuel Pump:<\/strong> One 12V EFI pump with a black 60 mm mounting bracket.<\/li>\n
- \nAdjustable Fuel Pressure Regulator:<\/strong> One regulator with a listed 20\u2013120 PSI adjustment range.<\/li>\n
- \nPre-Pump Filtration:<\/strong> One serviceable 100-micron inline fuel filter with selectable AN adapters.<\/li>\n
- \nPost-Pump Filtration:<\/strong> One serviceable 10-micron inline fuel filter for compatible EFI layouts.<\/li>\n
- \nAluminum Fuel Line Kit:<\/strong> 25FT of 3\/8 inch OD 1060 aluminum tube with line-forming tools and AN6 connections.<\/li>\n
- \nPump Adapters:<\/strong> One M12\u00d71.5-to-AN6 adapter and one AN6-to-M18\u00d71.5 straight adapter.<\/li>\n<\/ul>\n
The package brings the main fuel pump and pressure regulator<\/strong> components together, but it is not a vehicle-specific direct-fit system. Relay, fuse, complete wiring, fuel rail, injectors, return-line hardware, tank fittings, and additional vehicle-specific adapters are not automatically included unless listed with the selected package.<\/p>\n
\n\n
300LPH Pump Flow, Pressure and Voltage<\/h2>\n<\/summary>\n
\nThe included external inline fuel pump<\/strong> is designed for compatible 12\u201313.5V DC EFI systems. Pump output must always be evaluated with its corresponding pressure and voltage.<\/p>\n
\n\n\n
\n \nFuel Pressure<\/th>\n Test Voltage<\/th>\n Published Flow<\/th>\n<\/tr>\n<\/thead>\n \n 43 PSI<\/td>\n 13.5V<\/td>\n 300 LPH<\/td>\n<\/tr>\n \n 43 PSI<\/td>\n 12V<\/td>\n 255 LPH<\/td>\n<\/tr>\n \n 75 PSI<\/td>\n 12V<\/td>\n 200 LPH<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n The advertised 300LPH rating does not mean the pump delivers 300 LPH at every pressure. Actual flow changes with loaded voltage, regulator setting, filtration, line restriction, fittings, fuel type, and wiring condition. Select the pump from the required flow at operating pressure instead of estimating horsepower support from the nominal LPH rating alone.<\/p>\n
For buyers comparing a high pressure inline fuel pump<\/strong>, this unit has a listed maximum operating pressure of 75 PSI. It is an external EFI supply pump, not a mechanical gasoline direct-injection high-pressure pump.<\/p>\n
<\/figure>\n<\/div>\n<\/details>\n\n\n
100-Micron Pre-Filter, 10-Micron Post-Filter and Regulator<\/h2>\n<\/summary>\n
\nA reliable external fuel pump for fuel injection<\/strong> needs filtration that protects the pump without creating excessive inlet restriction. Install the 100-micron filter before the pump and the 10-micron filter after the pump in a compatible EFI layout. Follow the flow-direction arrow on each filter housing.<\/p>\n
- \n
- \n100-Micron Pre-Filter:<\/strong> Captures larger tank debris before it reaches the pump.<\/li>\n
- \n10-Micron Post-Filter:<\/strong> Provides finer filtration before fuel reaches the regulator, rail, or injectors.<\/li>\n
- \nServiceable Construction:<\/strong> The removable stainless-steel elements can be inspected and cleaned.<\/li>\n
- \n20\u2013120 PSI Regulator:<\/strong> Set pressure according to the engine-management system, injectors, and fuel rail.<\/li>\n<\/ul>\n
The regulator must be installed according to its port layout and return-line requirements. A wider adjustment range does not make it suitable for every EFI system. Confirm the required base pressure, vacuum or boost reference, return-line capacity, and gauge connection before installation.<\/p>\n
<\/figure>\n<\/figure>\n<\/div>\n<\/details>\n\n\n
25FT 3\/8 Inch Aluminum Fuel Line<\/h2>\n<\/summary>\n
\nThe included 1060 aluminum hard line provides 25FT of tubing for a custom feed or return route. Its listed dimensions are 3\/8 inch OD, 0.32 inch ID, and 0.05 inch wall thickness. The tube is supplied with tools for cutting, bending, and deburring during installation.<\/p>\n
- \n
- \nMaterial:<\/strong> 1060-grade aluminum, listed as ASTM B210 compliant<\/li>\n
- \nLength:<\/strong> 25FT<\/li>\n
- \nOuter Diameter:<\/strong> 3\/8 inch \/ 9.5 mm<\/li>\n
- \nInner Diameter:<\/strong> 0.32 inch \/ 8.1 mm<\/li>\n
- \nWall Thickness:<\/strong> 0.05 inch \/ 1.4 mm<\/li>\n<\/ul>\n
Plan the complete route before cutting. Use suitable supports and abrasion protection, maintain clearance from exhaust heat and moving parts, and avoid tight bends or unsupported sections. Confirm that the selected line size supports the required flow and return capacity of the complete system.<\/p>\n
<\/figure>\n<\/div>\n<\/details>\n\n\n
Installation Position and Electrical Checks<\/h2>\n<\/summary>\n
\nMount the pump close to the tank and at or below the tank outlet when the vehicle layout permits a safe gravity-fed installation. External pumps are designed to push fuel more effectively than they pull it, so a restricted inlet or high mounting position can contribute to noise, cavitation, or unstable supply.<\/p>\n
- \n
- Keep the pump and fuel line away from exhaust heat, suspension movement, drivetrain components, and road impact.<\/li>\n
- Use the supplied 60 mm bracket and suitable vibration isolation.<\/li>\n
- Use a compatible relay, fuse, power wire, and ground sized for the pump circuit.<\/li>\n
- Verify voltage at the pump while it is operating, not only with the circuit unloaded.<\/li>\n
- Prime the system and check every connection for leaks before starting or loading the engine.<\/li>\n
- If the vehicle is raised, support it with jack stands; never work underneath a vehicle supported only by a jack.<\/li>\n<\/ul>\n
This kit may be used as an LS swap inline fuel pump<\/strong> package when the line size, regulator, fittings, fuel demand, and vehicle layout are compatible. It is not automatically a plug-and-play LS or vehicle-specific kit.<\/p>\n
<\/figure>\n<\/div>\n<\/details>\n\n\n
Check Before Ordering<\/h2>\n<\/summary>\n
\n- \n
- Confirm the vehicle uses a compatible 12\u201313.5V DC EFI system.<\/li>\n
- Calculate the required pump flow at the intended base and maximum fuel pressure.<\/li>\n
- Verify the M12\u00d71.5 and M18\u00d71.5 pump connections and all vehicle-side adapters.<\/li>\n
- Confirm a 3\/8 inch aluminum line is appropriate for the feed and return layout.<\/li>\n
- Confirm the regulator range, return-line design, and reference-port requirements.<\/li>\n
- Confirm fuel compatibility for the pump, filters, regulator, seals, fittings, and line.<\/li>\n
- Allow room for the pump, two filters, regulator, brackets, and safe line routing.<\/li>\n<\/ul>\n
Verified compatibility is gasoline and diesel where the installation is designed correctly and oil-gas separation requirements are met. The current product specification does not confirm methanol or ethanol compatibility. This pump is also not a diesel common-rail injection pump.<\/p>\n<\/div>\n<\/details>\n
Is This EFI Fuel Pump Kit Right for Your Build?<\/h2>\n
Choose this kit when the project needs a complete custom EFI fuel pump kit<\/strong> with an external pump, adjustable pressure control, staged filtration, and a long aluminum hard line. Choose a vehicle-specific solution instead when the installation requires an in-tank module, factory electrical connector, integrated sender, fixed OE regulator, or direct-fit factory plumbing.<\/p>\n
- \nLength:<\/strong> 25FT<\/li>\n
- \n10-Micron Post-Filter:<\/strong> Provides finer filtration before fuel reaches the regulator, rail, or injectors.<\/li>\n
- \nAdjustable Fuel Pressure Regulator:<\/strong> One regulator with a listed 20\u2013120 PSI adjustment range.<\/li>\n
- \n300LPH External Inline Fuel Pump:<\/strong> One 12V EFI pump with a black 60 mm mounting bracket.<\/li>\n
