The Walbro high output in-tank electric fuel pumps are available in flow ratings of 255 liters of fuel per hour. These particular pumps flow significantly more fuel at higher pressure than standard-pressure versions. For example, at 80 PSI the standard 255 lph pump will flow around 132 liters (35 gallons) per hour. At that same 80 PSI the equivalent HP (high pressure) fuel pump will flow over 210 liters (50 gallons) per hour.
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.
