Well.... In a R33, it's got a 65L tank. The petrol light normally comes on when there's about 10-15L left in the tank.

So being down to the empty line doesn't necessary means it's empty.

I can confirm the fuel light doesnt come on when the key is turned to acc/on or w/e, only when you actually have low fuel. My fuel light begins to flash, more accurately pulse slowly as the fuel guage drops to around 0.5-1mm below empty. I could take a picture of it tomorrow if you want because I'm a poor karnt and have been driving around with the fuel light on for 50kms.

Jamesk,

Thanks dude. now i know. and to know that it only comes on .5-1mm under the empty line is handy to know as well...

Lets just hope that the globe isnt blown as I am on the empty line now......

You do realise some of you guys that it might not come on?

That bulb could be broken, the level sensor in the tank might have been played with and so on :)

As for waiting for a low tank of fuel before swapping the pump, don't. Better to do it with a full tank as there is less area for vapour to form if it's right @ the full marker.

That's what i was told anyway... I can see the logic behind it so i've not argued that point and always done mine with a virtually full tank.

A bit of fuel on your fingers won't kill you. Might give you cancer.... but then thats no different from outta bed these as everything gives you cancer :D

I don't know why you'd risk running empty :)

I tested mine so i know it works 100% and comes on exactly as it hits "E", something you can fixup/test if you change fuel pump etc.

But otherwise i wouldn't be "testing" it driving around or you might well find yourself doing the walk of shame with a jerry can

r31nismoid...

you said "I tested mine so i know it works 100% and comes on exactly as it hits "E", something you can fixup/test if you change fuel pump etc."

how exactly did you do the test & adjust it to comeon on the line of empty?

Painfully :D

When you have the whole assembly out you can play with it. Just flick the ignition and you'll see what i mean if you trigger the sensor.

Then you just have to trial/error fir the thing based on when you want to know how much fuel is left.

It makes much more sense once it's all apart in your hands as im bad @ explaining.

Femno/Matt or someone else might do a better job :)

So being down to the empty line doesn't necessary means it's empty.

Anyone wanting to check for the working existence of their light - well it's not hard to carry a jerrycan in the back for the 50km or so that it will take you to achieve the light once you've touched on the empty line.

I filled mine up with 58 litres to the click after my light had been on for a little while. If Charles is right about the 65L tank (and I still don't entirely trust him on it lol), then I had another 50-60km left in the tank.

From my experience it will fade on and off at first, then when you start to really get low it will stay permanently on.

The light fades on and off is because of the petrol in your tank is getting splashed around, so sometimes it hits the sensor and sometimes is not.

Then when your tank is almost empty, it doesn't matter how much it splashes, because there's not enough to hit the sensor and that's why the light stays on.

But I'm definitely sure the petrol tank is 65L on R33's and R34's. Because I've tested it myself countless times (not with a jerry can tho lol).

If you car is really thristy on petrol and takes 15L/100km, then you can still get 430km out of a FULL tank.

So for those people who say they can only get 250km out of a tank, then this might make you feel better :yes:

Because to be getting only 250km out of a tank, then your car would be drinking 26L/100km lol.

      7 Speed Auto transmission fluid change (Skyline, Q50, Q60, Fuga, Q70, A62 Titan and probably heaps of others including Navara...)

      By Duncan · Posted

      I thought I'd do a write up on an auto transmission fluid change for a the nissan 7 speed Automatic. At some stage the genius engineers decided that the fluid in the trans was "for the life of the transmission", (which seems kind of self supporting to me) and removed the dip stick and fill tube (funnily enough there is still a casting for it). Anyway, for this job you do need 2 specialist tools in addition to regular hand tools, jack and good chassis stands. You need a way to pump fluid up to the transmission; I got one of these but there are plenty of other options: https://www.ebay.com.au/itm/364584087070 Don't trust the generic listing though, it does not come with the required adapter for the Nissan 7 Speed. You need one of these, can't do the job without it: https://navarapart.com.au/product/genuine-nissan-patrol-y62-d23-np300-navara-re7-dipstick-fill-connector1 You need a heap of compatible transmission oil. Could be Nissan, could be anything else rated for Nissan Matic S. You need at least 10 litres, I had 15 to give it a better flush... Also, you need some biiig oil catch trays, at least one of these, or bigger if possible (volume was fine, size was very marginal): https://autobarn.com.au/ab/Autobarn-Category/Tools-%26-Garage/Specialty-Tools/Oil-Service/Garage-Tough-Oil-Drain-Pan-Black-16L---GT1068/p/TO03191 Finally, a measuring jug is very useful if your pump does not have volumes marked on it, I got a 6l one: https://www.repco.com.au/oils-fluids/fluid-accessories/measuring-jugs/penrite-measuring-jug-6l-pmj006/p/A5322648 Oh, and gloves.....this stuff is horrible (not as bad as diff oil, but getting there) ....First, jack up your car.....

      Duncan's V37.......race car?

      By Duncan · Posted

      So I mentioned the apprentice, @LachyK helped take the bonnet off. We just undid the nuts on the hinges and unclipped the gas struts, then pulled the bonnet back a little as the front was catching on the front bar.  I had a good look at everything today and have removed the rams, repaired/reset the hinges and bolted it back together like it never happened. I'll do a separate write up on the repair, and I also removed the poppers from the Fuga today too to save grief down the road.....as said above it is at least $5k to repair retail. I'm also happier about my ability to prepare a race car, and less happy about Nis-nault's engineering (I can hear @GTSBoy sAfrican Americaning) because the top hose of the radiator didn't slip off.......it snapped clean off. By practice I put the hose clamp hard up against the flare on a neck to make it least likely to ever move (thanks @Neil!). I guess that puts a little more pressure on the end of the pipe as it is further away from the rad, but still, that is pretty shit. I've put it back on for now as there was a fair bit of neck still there, but obviously there is no lip on the neck any more so I don't think I'll track it again until I have a new rad. Speaking of which....more research required. It looks like Koyo makes a standard size radiator in ally which I'll grab in the meantime, but I really want something thicker so might have to go custom in the medium term (ouch) Coolant still needs a refill and I have the pressure tester on it over night, but other than a wash down of the engine bay it seems alright. And @MBS206 noted something noisy on the front of the engine and I think I agree....time for a new accessory belt and tensioners I think.

      our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)
