The “Gold standard”

HP (High Pressure) - GSS340,GSS341,GSS342 are the main Walbro 255 high pressure intank fuel pumps. GSL392 is also a 255LPH high pressure pump, however this model is an inline fuel pump, which means it usually mounts outside the fuel tanks. 
If your vehicle is used for racing purposes, heavy hauling, or in high powered turbo vehicles, OE spec Walbro Fuel pumps may not supply enough fuel to satisfy your engines needs. The Walbro 255LPH high pressure fuel pump is highly recommended for vehicles with engine performance purposes. Installing a Walbro high pressure fuel pump in a non-performance vehicle will not damage your motor. All fuel first passes through fuel injectors and a fuel pressure regulator which only send the required amount of fuel into the intake manifold, sending the unused fuel (usually more than 1000%) back to the fuel tank.

The Walbro GSS line of high-performance fuel pumps
have been widely recognized as the “Gold Standard” in
the industry for more than 20 years. Walbro GSS pumps
are compatible with a wide range of vehicles, feature
unsurpassed quality, durability and performance, and are
designed and manufactured in the USA.
