Walbro HO 255Lph Fuel pump

Now that you have the injectors, you need something to supply the needed fuel pressure at high boost.  Choose from some of the best when you choose Walbro.  Please specify application and if you require an installation kit.  On Evolutions without a prior walbro installation the install kit is mandatory for safe operation.  This is a high output pump, not to be confused with high pressure.  It will max out above 80psi of fuel pressure and start to drop off.
