fule guage = screwed? - Toyota Nation Forum : Toyota Car and Truck Forums

Is it normal that to make the gas guage read full you have to fill the shaft leading into the tank in a AE86 GT-S?

And I'm also experiencing some strange things with the rate at wich my fule is being used. like it will take a quarter of a tank of highway driving going to one place and it will take a quarter and a half to half a tank to come back going the same speed... Some times it seems like the first half of the fule gets used slower then the last half which makes no sense cuz the car gets lighter as it uses up fule.

its true.. i get the same thing..
its the way the tank is shaped.. thats my guess

lol.. Your sender is just fucked.. It happens to a lot of us ae92'ers.. the senders go to hell

As of now.. I'm always driving around below E.. lol.. then as the tank approaches like a 1/4 it will start to work.. n then not work.. then work then at 3G left the light will start to come on.. and then if i fill the tank up the sender will go up n work fine.. for a little bit.. depending on how i work the throttle and i have no fuckin clue why this affects anything, the gauge will move around or go from F to it's normal position below E.. lol go figure.

18 year old car, your sending unit could be messed up, or the float has saturated with fuel

not really worth fixing, just reset the tripodometer everytime you fill up, i've driven around for years like that

mine is messed up too...i fill up and the needle barely goes past 3/4

...and also it seems as if the gas is being used up slower for the first half of the tank...once the needle gets below 1/2, the gas seems to run out faster

...and this is with the same driving style/speed every day, but i still get about 500km/tank...ive gotten used to it so far...

assuming the old sending units are in perfecot working order (thats a brave assumption

) maybe getting from point A to B you're moving uphill/downhill....and B back to A vice versa, maybe thats affecting the fuel float?

on the 400 to barrie it is up hill at times but the other half being on the 401 or 407 it is more or less on the flatter side. But I get the same thing some times in the city where there arn't that many hills. and when I'm just on the 401. So hills arn't that much of a factor.

sounds familiar, i seem to be averaging around 390km/tank now

and the gauge also goes up & down. how much does a sender cost approx. (Cdn)?

It's winter time man.. I seem to kill more gas now than in the spring/summer. What I always wonder is.. why in the winter my tank seems to take more than 40L to fill when in the spring/summer it takes like 36-38??

I swear I haven't gassed up once this winter that it hasn't been 42L-44L.. I usually fill up when my gauge starts to flash me with the empty tank light.

^^ mofo cause they "correct the fuel to 15*C"

what that means, well i have no clue, i'm no scientist but my guess is that the gas is more condensed when cold so to fill up what really is 40L it takes 44L condensed fuel and the machine reads its as 44L because it doesn't read it as condensed.. instead corrected at well above 0*C.

thats my theory

|PuNiSh3R| · 03-10-2004, 06:16 PM

So maybe they make it slightly more potent in the winter.. because of the colder temps you need to run a bit richer.. so that would account for a slightly heavier gas useage in the colder months.. so I'd assume if they made the gas more potent.. if that is possible.. to help counter-act the rich running.. although makes no sense really because it's not like the engine knows what octane or anything gas is going in.. eh wtf do i know..

RedruM · 03-10-2004, 06:27 PM

but that wouldn't make the tank size grow from 40L to 44L

oh well who knows and who gives a rats ASSSS

FUCK iT
jus fillr up and drive that slut of yours REN69

Nice... good to know I'm not the only one with that problem.

My AE91 sedan has that problem. Seems like the fuel gets used up faster as I near an empty tank. Sucks when I'm on the highway when that happens. But I just regard that as normal now .. nothing worth looking into

|PuNiSh3R| · 03-10-2004, 11:22 PM

Yea.. fuck that shit yo.. nothing to worry about until the engine stalls.. then you know you need gas!

These gauges are just horribly inaccurate.. It's really nothing to worry about. When the fuel light comes on you know you got usually 3G left. Like for me now I know it's flashing on and off.. but not steady enough to regard.. so I know I probably got like just under 4G left.

my gauge drops almost instantly from full to half within 50 km, then it seems to work normally, I got new sender unit (old one leaked) cost me $250 installed. I think I got ripped. I just use my trip-meter. drive around with a jerrycan to figure out how much you get to the tank and then just filler up every time.
