Stagea Fuel Pumps

[tRUkbOY]

Ok, not sure if this is a subject covered before but I'd thought I'd bring it up.

People talk about fitting a fuel pump to their Stagea but I haven't ever seen any detail about it.

I currently have a Walbro 255 in the tank behind the 26 but to be honest its not right. It won't run right when its cold (like its starving of fuel) & if you thrash it it doesn't seem to catch up for a while. Talking to a fuel pump expert he said that some Nissans (Z32 300ZX for example) run variable rate earths at the ECU & that may be what is causing my problem. I personally have a re-shelled 260RS if that makes any difference (including the entire 260RS wiring loom) so I'm just curious as to whether anyone has had fuel pump problems with their Stagea/260RS.

I have access to a Bosch 044 with a the appropriate fittings to adapt to the Nissan setup but have been told (by the same guy) that I will at the very least need to change my fuel pump relay for fear of burning it (or the wiring/ECU) out. Of course I haven't wanted to risk a 260RS ECU so haven't taken it any further.

I'd like to wind the boost up to 1 bar but I don't want to risk a lean out with a sketchy pump so I'm holding back at the moment but I can tell you my RH foot is getting itchy.

What are other people running in their Stagea/GTS25T/GTR etc etc?

On a similiar note; how do people wire up secondary fuel pumps? Into the same earthing point (via the ECU)?

I think sydneykid has mentioned it before, the Walbro needs 13 + volts to perform at 255l/hr

You may only be getting 11 volts and therefore your pump is not pumping enough fuel for your thirsty rb26

I had a Walbro pump installed in my Stagea and the workshop who did it always installs new power lines to make sure it is receiving all the voltage it requires so it won't lean out.

Ahhh I see. That makes sense.

I had considered hard wiring the pump with a direct feed from the battery but my concern is of the safety side of it; I don't want it to keep pumping fuel if I ever crash it (well if someone crashes into me )
