-10% Walbro / TI Automotive 255 and 335 LPH Inline Fuel Pump

Now With Bigger Flow Option!

Everyone in the industry recognizes this pump. The iconic GSL392 Inline Fuel Pump produced the TI Automotive, originally under the Walbro brand. And everyone knows that it flows 255 LPH. But as I write this I am about to deliver a bombshell announcement. Starting mid-April 2021, TI is going to produce a new version of this pump called the GSL396 that produces 335 LPH of flow at 43.5 PSI at 13.5 VDC. That is enough fuel to feed an _additional_ 200 HP naturally aspirated or 170 HP turbocharged. Just what the doctor ordered for higher-end engines that were out-pacing the fuel flow of the 255 LPH pump.

You can't improve on perfection. Simply stated, there is not another high-performance, high-pressure-capable inline fuel pump in the world that comes close to matching the original TI Automotive 255 LPH in-line fuel pump for quality or price. For that reason, no other pump is so duplicated. Buy your Walbro 255 LPH GSL392 in-tank fuel pump from EFISystemPro.Com to guarantee that you are getting a genuine Walbro pump made by TI Automotive.

Note that the inlet and outlet adapters on this pump are neither pipe-thread nor AN.  They are 10mm x 1.0mm straight thread.  Finding inlet and outlet adapters in the local marketplace is extremely rare.  Save yourself some frustration and buy them with the pump.  The GSL396 pump is nearly identical to the GSl392 except that it measures 1.3mm longer from end-to-end.

The Holley Billet Pre Filter and Holley Billet Post Filter can also be purchased separately.
