Walbro Fuel Pump

[Shannond]

hey guys my fuel pump is going in my NA R33 series 2, i was just wondering if i put a walbro fuel pump Flow rate 255 L/H in if it would be okay? Would it be out of tune because of it pumping to much fuel or will it be fine?

Fuep pump has nothing to do with the state of tune, so will be fine.

okay thanks because someone told me that he rekons it will lag or something because it will be trying to pump to much fuel or something? so my car will run and be exactly the same yes? just a more reliable fuel pump?

What u were told may apply to non bosch jetronic fuel injection set ups and carbys however 99% of efi cars changing the fuel pump has no impact on mixtures... The pressure is regulated by a pressure reg on the engine fuel rail and any excess fuel above this pressure is fed back to the fuel tank. Upping the fuel pressure will change mixtures.

oh ok thanks for that i thought so i just wanted to make sure, is it hard changing the fuel pump

There is a DIY for a bosch pump in the tutorial section, same deal with the walbro apart from the size of the pump.
