noisy fuel pump

You may find that somebody has bypassed the fuel ECU controller (becuase its failed), which will cause the pump to run at full speed permantly, hence the noise.


Remove the Rear seat, and the rear trim on passenger side and you should see a couple of electronic boxes. If you see any extra wiring that looks non standard then thats whats happened.


If it does turn out to just be the pump on its way out then I have a couple spare. £50 each.

The standard fuel pump is good for about 600bhp anyway so why would you need to upgrade it now?!

One of the last mods you ever need IMO :rolleyes:


Absolutely! I don't think there are ANY Zs in the uk that would require an uprated fuel pump! To get over the limit of the stock pump you would more than likely need to be running race gas in order to achieve the power levels in the first place....
