Fuel Gauge

[patullose]

Hey guys, just wondering if u guys are having the same poblem as me...

the only accurate responce i get from my fuel gauge is when it is full or empty, when it is inbetween i floats up and down and doesnt really give me a a good reading, and i never really know how much fuel i have. and when i turn my car on it always is a notch below the one it was previously on when i turned it off.
just wondering if this is a normal VR thing or do i need a new sensor

thanks guys
sean, :thumbsup:

Hmmm. Haven't had that problem (yet), but mine does stick occasionally on empty.

yah i had a problem that mine was sticking on empty the only way i coud get it to work was just to tap the glass

Sounds to me you have a common case of 'commodore fuel Gauge' All the commodores i've seen are the same, they move up and down depending on what level your car is. going up hills my gauge goes down, and goin down it goes up. going around left and bends it goes down and right handers get it to climb.

I just keep the tank full, it solves all my woes...

lol so nothing i can do about it? all commo's the same?

driven quite a few cars and all cars have this problem but gawd not as bad the commodores, also mine too does tend to stick on empty somethimes. maybe the fuel sender is getting old or something, i'll happy to volenteer what happens if a new one put in but won't anytime soon. i got better things to spend on then the fuel gauge, still maybe someone has replace the sender or something or has put in aftemarket fuel gauge and maybe even fixed the problem.

Yep i get the exact same prob, especialy on hills but also one more weird thing is that when i drive the car first thing in the morn, it seems lower than what it was the previous night, from what i think, its probly because the fuel expands when warm giving a higher reading than when it is cold, but i dont quite understand why the petrol would be warm in the first place.

got the exact same problem. then next morning this guage is 1 bar lower than the previous night.

but i dont quite understand why the petrol would be warm in the first place.

engine bays are quite hot in case you didnt know:yeah:
the movement of fuel from tank to fuel rail, and then from fuel rail to tank for unused fuel creates a fair bit of heat, i know a lot of people that converted from carby to efi, and had the return line hooked up to the surge tank, but the fuel was too hot and started causing problems with the pumps, so had to run it back to the tank where the larger amount of cooler fuel is enough to cool down the small amount of warmer fuel, if that makes any sense.

ye mines lower than the nite b4 when i first start it, but during the drive it kinda creeps up (providing im on flat ground!!) but ive been told by multiple ppl about the "dodgy commodore fuel gauge" so i never let my tank "appear" to be lower than 1/4..
