MM2death Posted January 13, 2003 Share Posted January 13, 2003 R33 problem? or R32? thanks Originally posted by YBSLO4 Clearly someone should have told you not to ever boot the throttler when teh tank is below 1/4 full?? Doing so is asking for trouble mate... when it is below a 1/4 it is hard enough for the pump to suck fuel normally let alone sloshing around when you boot the crapper outa it and hit redline... this would explain also why you cut out, was because the pump coudln't pick up enough fuel to match for the amount of air coming in... you lucky you didn't blow it :S Be careful mate.

2fardown Posted January 13, 2003 Share Posted January 13, 2003 If you run the tank near empty you also pick up all the sedaments/dirt in the bottom of the tank, which in turn can harm your engine.

If you run the tank near empty you also pick up all the sedaments/dirt in the bottom of the tank, which in turn can harm your engine. So, that means the pump moves up and down in the tank, depending on how much fuel is there.Get real, the pump will pick it up with an overflowing tank. That's why there are filters in the system, on the pump itself, and before the fuel rail. The R32, at least, has a sort of surge tank built around the fuel pump area to reduce the movement of fuel away from the pump pickup. Hammering it probably is not condusive to keeping the fuel near the pick on a lowish fuel level. And considering the tank is much wider than it is deep, a 1/4 tank is not a lot of fuel. Fuel surge will be most noticeable on RH turns, since the pump is located towards the RH side of the tank, and a RH turn will throw the fuel to the left, away from the pump.

I'm not sure what you are getting at. But my point still stands about the sedaments.

dAVE Posted January 13, 2003 Share Posted January 13, 2003 2fardown - i agree, but a) if you have a clean tank and B) your filters are doing their job... then really its not a big issue... still i wouldnt reccomend it. Better to be safe than sorry. Link to comment https://www.sau.com.au/forums/topic/8600-can-this-be-verified/#findComment-125756 Share on other sites More sharing options...
Guest Boxhead Posted January 14, 2003 Share Posted January 14, 2003 this is my theory, the only reason there is the crap down the bottom is because no one ever uses that bit of fuel that keeps sitting there... if you keep using it you shouldnt get the build up lol.. that said i have only ever hit he fuel light on my car, and i wasnt booting it.. it was on the way to the petrol station too Link to comment https://www.sau.com.au/forums/topic/8600-can-this-be-verified/#findComment-125904 Share on other sites More sharing options...
2fardown Posted January 14, 2003 Share Posted January 14, 2003 Do R33's have fuel lights? Link to comment https://www.sau.com.au/forums/topic/8600-can-this-be-verified/#findComment-125906 Share on other sites More sharing options...
DAMQIK GTS-T Posted January 14, 2003 Share Posted January 14, 2003 Yes R33 Do have fuel lights about 50 K's to dead empty (light driving) PS I have never had a problem cornering hard with a tank on E to me the best time to do it as the car is a bit lighter. my 2 cents Link to comment https://www.sau.com.au/forums/topic/8600-can-this-be-verified/#findComment-126678 Share on other sites More sharing options...
red17 Posted January 14, 2003 Share Posted January 14, 2003 Isnt this what surge tanks and return lines are for? Surely the pump isnt that sensitive. The bloke dispensing the advice isnt from the carby era is he? Ive never heard of this in any car, let alone a modern EFI motor.

akeenan Posted January 14, 2003 Share Posted January 14, 2003 Same goes for just about any car. If you run the tank near empty you also pick up all the sedaments/dirt in the bottom of the tank, which in turn can harm your engine. what happens if you bought a new car and run it empty every time then this would not be a problem. I drive around many times with hardly any petrol in my car and never have any problems? also if driving around with 1/4 of a tank "harms" ur car shouldnt the light really come on at 1/4. 1/4 of a tank harming the car? strange very very strange, im not convinced Link to comment https://www.sau.com.au/forums/topic/8600-can-this-be-verified/#findComment-126800 Share on other sites More sharing options...

I was talking about the crap in the bottom of the fuel tank. My brother has a 180sx basically ran his tank just near empty and in effect clogged up his fuel filter full of sh!t. If you aren't convinced...honestly I couldn't give two sh!ts.
