Fuel pump

[Robo]

HI There,

If a fuel pump is on it's last legs what are some tell tail signs that it needs replacing?

Could one be that when I turn the boost up (to say 11 psi) and floor it a sudden fuel cut comes in.... like all power stops, cause when I turn the boost down to 9psi it works fine...

Also when I touch the accelerator lightly I can here a high pitch noise from the back of the car.. (and also when cruising at 60 I can also here it then).

So that said, if it is my fuel pump should I just replace the unit with a new factory Nissan one or buy a second hand GTR or what?? ( I have an R33 gts-t with FMIC, Air, boost - 163 rwkw's)

Are they just a simple replacement or do they need a lot of work to get in?

Thanks for the advice.

Welcome to the world of boost cut - above 12psi and your computer says I've had enough.

You can buy a defender to stop this happening, but if you are thinking about upgrading the ecu or fitting a SAFC(I think), you wont have to worry any more.

As to what to do if you have to replace your fuel pump (which I dont believe you do yet) that will depend on what your future hp goals are

AFAIK im using a factory ECU and a factory Fuel Pump and my car drives dead smooth with 192rwkw @ 12psi.

I dont think your problems are your fuel pump but then again i know about 3% about cars.

Thanks Steve & Benm,

That is really good info....

Yeah my power goals aren't really that high.. Not looking for more than 200 rwkw's...

SAFC is something I would buy...

Regards

You shouldn't have any problems with the stock fuel system with that sort of power goal. I am at 203rwkw with completely stock fuel system - a SAFC will certainly help you get there.
