FUELAB 3/8 SAE Make Outlet Low Pressure In-Tank Lift Fuel Pump - 49503

This engine parts collection covers oil catch cans, thermostats, thermostat housings, radiator components, coolant accessories, engine covers, fuse box covers, cap covers, throttle bodies, supercharger pulleys, idler pulleys, tensioner pulleys, and engine bay dress-up parts for trucks, SUVs, muscle cars, boosted builds, high-horsepower street cars, and performance vehicles that need better reliability, cooling, airflow, oil control, and under-hood styling. The collection is particularly strong for Dodge Challenger, Charger, Durango, Jeep Grand Cherokee Trackhawk, and Ram TRX platforms running 6.2L Hellcat, 6.4L HEMI, and 5.7L HEMI engines, where oil catch can and cooling upgrades address known OEM weaknesses in the PCV and thermal management systems. Import performance platforms including GM LS-based builds, Chevrolet Camaro, and Corvette applications are also represented through Mishimoto, CSF, and ZPE GripTec product lines. Builders who invest in engine bay organization and reliab...

A properly designed fuel delivery system is the backbone of any high-performance engine build, ensuring the injectors or carburetor receive a consistent supply of fuel at the correct pressure regardless of engine load, RPM, or fuel demand. From factory replacement pumps keeping daily drivers on the road to high-flow in-tank modules supporting 1000-horsepower builds, the right fuel delivery components prevent lean conditions, injector damage, and fuel starvation at the worst possible moment. Modern EFI systems are particularly sensitive to fuel pressure variation, with even small drops causing misfires and power loss under hard acceleration. Whether you are restoring a factory system or engineering a purpose-built race setup, matching pump flow rate and fuel pressure regulation to your injector and engine requirements is essential. Popular Upgrades Top-selling fuel delivery components include Aeromotive Phantom in-tank fuel pump kits that retrofit into factory tanks without custom fa...

A fuel pump is the foundation of every fuel system, and matching pump flow capacity to your engine's actual demand is one of the most critical decisions in any EFI or performance build. Undersized pumps cause lean conditions under hard acceleration that damage pistons and injectors, while oversized pumps can pressurize the fuel system beyond regulator capacity and require additional return plumbing to handle excess flow. Modern in-tank brushless pump designs from Walbro, TI Automotive, and Aeromotive deliver high flow rates with lower current draw and longer service life compared to older brush-style commutator designs. Diesel lift pumps serve a different function, providing pressurized supply to the high-pressure injection pump while also filtering water and particulates, and selecting the right lift pump for your diesel platform directly affects injection system longevity. Popular Upgrades Top-selling fuel pumps include the Walbro 255 LPH and 450 LPH in-tank pumps for popular turb...

Fuelab has established itself as a premium manufacturer of precision fuel system components designed for high-performance EFI applications where conventional fuel system hardware falls short under sustained high-load conditions. Known for their billet aluminum construction, tight pressure regulation tolerances, and comprehensive AN-ported product line, Fuelab components are used by professional race teams and serious street performance builders who demand measurable fuel pressure stability across the full RPM and load range. Every Fuelab product is engineered with a focus on internal flow efficiency, with oversized passages and precision-machined valve seats that minimize pressure drop while maintaining regulation accuracy. Whether you are building a naturally aspirated high-revving engine or a high-boost forced induction platform, Fuelab offers a component for every position in the fuel system from tank to rail. Popular Upgrades Top-selling Fuelab products include the 515 Series ad...
