Hey there

i have an r33 gtst and my fuel gauge will not move of the full mark until i have done around the 300km's mark. Im wondering if this is a common problem for the r33 skylines cuz one of my mates 33 does the exact same thing but around the 250km's mark. does anyone have any idea of what i can do to fix this so that my gauge goes down consistently with my petrol usage?

cheers iLEC ;)

Yeah mine does similar - but only until about 50klms or so - after that it moves.

Skyline fuel gauges are notorious for being misleading....

for example, at the empty line once i pumped up to 45 ltrs indicating 20 ltrs left, then another time at the empty line i pumped up 55 ltrs indicating 10 ltrs left...go figure ;)

Edit - could explain why my friends r33 was full tank, then the next time he drove it - it was half tank....

Yep - I had the same sort of problem. Think I have solved part of it anyway. I picked up my mint S2 R33 25T 2 months ago and put in my first tank of fuel... Needle read full for about 120 kays then it jumped to empty. I shat myself cause I thought it had used a full tank in 120kays!! My mechanic replaced the sender unit in the fuel tank and this helped. The sender unit was half of the problem as it was stuffed. The guage still fluctuates a bit, so the next thing im looking at is the actual guage in the dash. I reckon it sticks. I have seen it jump from full to a quater in the space of seconds while I have been driving (with a new known good and tested sender unit in place)- SO... Out goes the instrument cluster ands in goes the 320kph nismo dash with much attention being paid to the fuel guage!! ;-)

Hope this helps u guys!

Cheers,

Chris.

the needle will move around a bit depending on the angle of the car. if you park sideways on a hill then it will change the reading. this is due to the position of the sensor. hold a glass of water at an angle. the water doesn't stay level with the cup, but level with the ground.

if you fill your tank right up you should drive about 30-50km before the needle moves. this is because you generally fill up well past what the sensor sees as full , so you use up fuel before the sensor reads any change.

    • Wife wanted basket things in the wardrobe in our temporary house. Thought about ripping our the wardrobe and fitting the entire IKEA set, but it's a temporary house and we want to move in a few years. So IKEA advertises this as a 50cm unit, however the actually basket and rails measure 46cm wide. Only issue was depth, IKEA stuff is quite deep, where as the builder special junk is super shallow at less than 40cm. Send it, chopped the rails, then offset the mounting holes, job done, happy wife, less shit scattered all over the bedroom. Did the same to the other side too. Also drove the Skyline shit box today, dropped off oil at Supercheap Auto. I didn't realise they only now take max 2x bottles per visit. I visited 2x Supercheap Autos.  
    • I've seen similar actually in my situation. You never know what tables are attempted to be used when the car thinks it's -99C or +200C. The fail state is not usually that extreme but you know what I mean - it was in my case though! This is where being able to read all the sensors is useful cause you see this stuff really quickly.
    • The above is very important. However as long as you keep timing relatively low, it's plausible to make your own knock ears and plausible to learn to tune with a modern ECU that can do wideband O2 correction like a boost controller. I mean if you only have one viable road to even drive the car on, learning to tinker to this level may be worth doing given you can't do much else with the car...?
    • I find the fact that the rear plate has to be bent inwards at the rear not so bad: but the front is just awful: It's like come on. (these are my very old, now retired/turned in plates) TBH it is a lot of money to fix a minor issue, the fact I said "I'll never really spend the money on doing this" is why people ended up buying them as a gift for a 'car guy' who can be hard to shop for.. for car guy things.
    • I just bent the ends of my premo plates. It even went through Regency like that after the engine conversion and the inspector (a great bloke!) just squinted his eyes and said "I didn't see that". Plates, and how they look, are just something that have zero importance to me.
