These Walbro high output in-tank electric fuel pumps produce flow ratings of 255 liters of fuel per hour. These particular pumps flow significantly more fuel at higher pressure. 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.

Walbro in-tank electric fuel pumps utilize a proven gerotor design. The outside dimensions, however, are compact enough to fit existing hanger assemblies, without modification. These are complete fuel pump kits and include all drop parts and accessories.  Also included is an inlet filter that meets or exceeds original equipment specifications and provides improved filtration and durability.

Questions our customers have asked...

Can this fuel pump replace my own fuel pump that's on my g35?

Response: This pump is a higher output but will fit. Drilling of the siphon jet on the assembly to keep base pressure stock may be needed. Regards, The Z1 Team

Can this pump be installed into any Z32 with no modifications? I will be installing this into an NA 2+0 fuel tank, with a TT swap. Does the various speeds of the pump or wiring of different models have any effect on the installation of this pump?

Response: It will go right in without modification on a 2 seater. The pump controller is what manages speeds and you will still have 2 speed control. We recommend having the NA ecu socketed and upgraded for the swap. Regards, The Z1 Team

If this is used to replace the OEM pump in a G37, can it be installed without any modification? Will the increase in fuel pressure cause problems further down the line, i.e. the injectors? Thanks

Response: We would recommend adding the CJ install kit at the same time. Available here: (Link) We have not seen any issues develop with injectors.

the whalbro 255 fuel pump for nissan 350z is plug and play or do i need to make modifications for installation?

Response: Fitment into the assembly is similar to stock. We would recommend adding a new pump grommet (Link) and tank O-ring (Link) Also you may need to step up the size on the siphon jet if your base fuel pressure is too high. We usually handle this on a case by case basis depending on the fuel system.

I currently have the VHR manifold swap on my 350z HR. In the VHR fuel rail I am running R35 injectors I want to retune my car on e85 and would wanna know if any modifications are needed for this fuel pump to go in my Z

Response: When installing a higher flow pump most will slightly oversize the siphon jet orifice to keep base pressure from being too high. Also it is a good idea to pickup a new pump grommet (Link) and tank o ring at the same time. (Link)

Is this pump plug and play for a 2012 370z Touring or do i need to make modifications for installation? Thanks!

Response: You will probably need some minor trimming but we recommend the CJM Fuel Pump install kit with it found here (Link) And the Bulk head O-ring found here (Link)
