Fuel Pump Running With A Cut Wire

[Nic_A31]

This wire isnt connected, the pump is running as per usual.

i opened the tank up tonight to see if remounting the pump could reduce a very loud whinning the apparently 33 GTR fuel pump makes.

Assuming the pump was ran out dry hence the loud noise, as remounting made no difference.

What does this wire do exactly, does anyone know?

It's meant to connect to that capacitor looking thing right near it in the picture.

Traces back to a yellow wire with a blue stripe.

Aaaaand, what other cradles can I use?

Cheers guys.

That's the sensor for the low fuel indicator. The pump will run with only the power and earth wires that go to the pump itself.

Thanks dude.

Time to replace cradle I think, connections on the other wires look like they're about to go.

I believe S13 is the go ?

I still haven't done mine. But here are some s13 cradle pics. Looks the same except the float position. It might foul on the tank baffles.

Sorry for the imperial measurements, people keep stealing my metric tools. 9" is about 23 cm.

I used a S13 fuel pump bracket but with the 040 I had to chop the bottom plate off so the pump would fit in as the 040 have a built in filter on the bottom.

S13 is no good. It's about 6cm too long and fouls on the bottom of the tank.

I'm going to try to cut/weld mine to fit, but it will be a few weeks before I get around to it.

A32,B14,B15,D22,N15,etc all have the same bolt pattern for the lid, maybe one of those would be a closer fit...?

so no 2 a r32 one?

I switched t he pumps between my road Ceffy and the project.

The project one had an inbuilt filter at the bottom of the pump, and fitted fine...the other one didn't, and with the filter on, it wouldnt quiet fit.

I cut the end of the bracket off with an angle grinder (stupidly, while the bracket was still soaking wet in petrol....nothing happened though, woo), to make it fit.

The pumps themself looked the same size except for the filter adding some length.

Does this mean there are different brackets that came from the factory?

Donar was from a 20DE (turned 20DET), the tank it went into was a 20E.

One more thing...the Ceffy with the supposed GTR fuel pump, had a pressure rego in the cradle, but the project one with a factory pump setup didnt....possibly a GTR cradle+pump both used ?

I'm using a GTR pump in mine right now. It has a rego on the top of the pump, not on the cradle.

I dont think you have a GTR Cradle. In R32/R33 GTRs (all GTRs?) the cradle is not part of the lid/sender assembly, it is mounted to the bottom of the tank.

Be careful if you use hose clamps to attach the pump to the cradle. I think I tightened mine too tight and squeezed/ruined the pump. It started whining, so I tightened it, and it got worse.
