The Walbro GSL393-3 fuel pump – 155 lph gas inline universal is the OEM-quality replacement and performance upgrade choice for carburetor and port-fuel-injected engines demanding reliable, consistent fuel delivery. Built to Walbro's exacting standards under the Ti Automotive division, this compact inline pump handles high-flow demands across a broad spectrum of muscle cars, hot rods, and modified street vehicles.
Whether you're rebuilding a classic carbureted engine or upgrading a fuel-injected platform, the 155 lph flow rate delivers the volume needed for naturally aspirated builds and moderate forced-induction applications without sacrificing pressure stability. This inline pump utilizes proven rotary-vane design with integral check valves and bypass regulation, maintaining precise fuel pressure across the RPM range while minimizing heat generation during sustained operation.
The GSL393-3 architecture prioritizes low electrical draw and whisper-quiet operation—critical for street and daily-driver applications where pump noise invites unwanted attention. Sealed commutator brushes and quality internal components ensure durability in fuel systems exposed to ethanol-blended gasoline and seasonal storage, while the compact design allows flexible mounting in engine bays where space is tight.
