Walbro 255 fuel pump on test rig
This shows a Walbro 255 makes 250cc/min at 3 bar and 200cc/min at 4.8bar which is max before blow off. Our new pump flows 37% more, as much as a Bosch 044 and fits in tank on many applications. Its no longer necessary to have an outboard fuel pump for big bhp. email me on [email protected] for more info.
