The “Gold standard”
HP (High Pressure) - GSS340,GSS341,GSS342 have been the mainstream Walbro 255 LPH high pressure intank fuel pumps for many years. Recently Walbro released a uprated version of these pumps which are the GSS350, GSS351, GSS352 and are rated at 350LPH.
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 and 350LPH 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 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.
The difference between the 3 model of pumps would be the inlet position. Note that the GSS34XX series is 255LPH whiles the GSS35XX is 350LPH.
The GSS340/GSS350 has a larger 22mm centered inlet.
The GSS341/GSS351 has an 11mm inlet offset from the outlet 180 degrees.
The GSS342/GSS352 has an 11mm inlet in line with the outlet.
MORE PRESSURE = MORE POWER
High pressure GSS Pumps
- F20000311 = GSS340 = GSS350 : 22mm center inlet
- F20000312 = GSS341 = GSS351 : 11mm inlet, 180 degrees from the outlet
- F20000313 = GSS342 = GSS352 : 11mm inlet, in line with the outlet
- F20000311 = GSS340 with a higher pressure relief.
- F20000312 = GSS341 with a higher pressure relief.
- F20000313 = GSS342 with a higher pressure relief.
- GSS350 = GSS340 with higher flow at 350LPH
- GSS351 = GSS341 with higher flow at 350LPH
- GSS352 = GSS342 with higher flow at 350LPH
The images below are to illustrate the physical differences of GSS340, GSS341, GSS342 and the uprated versions GSS350,GSS351,GSS352 fuel pumps. As well as any other fuel pumps in the GSS family.
This also applies to the following pumps: F20000311, F20000312, F20000313
