Walbro 525lph Fuel Pump

The F90000285 is the highest performing fuel pump in the Walbro lineup. This pump is identical in form factor to the F90000267 and F90000274, but has a slightly higher output. Like the F90000274, this fuel pump has a high pressure relief valve for high boost applications. Due to the additional heat this pump generates, we generally recommend this fuel pump be used as a secondary pump in conjunction with a F90000274 primary; however, it may be used as a primary pump for demanding applications.
