Hi, Can anyone tell me where I can check if my fuel guage is working properly. I used about 1/8 of a tank a couple of days ago (roughly 150kms), but today the guage read a full tank. Thanx, Larry ---

240sx fule gauges seem to have a problem lol. It usualy has to do with the float in the tank. Basicly the car takes a reading from the float that tells the gauge how full the tank is. So if you car is on a incline of in a corner it will effect the gauge. If you want to know how much gas you have just take a look while on a flat peice of roadway. ---

If you want to know how much gas you have just take a look while on a flat peice of roadway. Acutally, it’s just been sittin in my garage, and the parking lot of work. Usually with my car, if I’ve been on a incline/decline it will have a false reading, but usually corrects itself in I would say 10-15 minutes. It’s just weird, cause it’s been stuck at full tank for a while now. ---

My s13’s gauge has been ok. My only complaint is the ‘low gas’ light I think it comes on when you are OUT of gas As in: Hey are you wondering why your car isn’t running? No gas fool. ---

Ya ive had the gauge pinned on the stopper and the light didnt come on. Also is it just my car or does it take like 10 min for the gas gauge to fill up after you fill the car up? ---

On my 95 I find when making a right hand turn the gauge gets higher and left makes it lower (so when i want to be happy I make a right lol). After filling it the gauge dose go up but not super fast the last 1/4 seems to take the longest. Realy its not going to ever be perfect it just supposed to give you a good idea of how much you have. ---

I know this is sort of an old thread, but i didnt want to start a new thread on the same subject. But yesterday I threw in 20 bucks of gas and needle was at half-full. That was in North York, drove to my house. Then went to work and back (only 3k total distance). Now its on empty. So I threw in another 15 bucks of gas earlier today. The needle moved a hair above E. So I’m pretty sure the gauge is acting up. So heres what I want to know, how can I fix this. Or is it too much trouble for what its worth? ---

Like I know what you mean with the needle reading up and down a bit. But I mean it was at like 1/2 full and then it was at E like 30-40 kms after. Hmm… maybe I should fill the tank completely and see what happens. ---

^^^ does you gauge work right now ? or is the needle under the E and \_\_ line ? if so… you lost the ground on your sending unit “happened to me when i put my walbro in” it broke 2 days later and I had to fix her up ---

Easy now, I was the one that brought back the old thread. Now heres a little update. I went to CT to pick up something and on the way there the needle was a bit above E. When I got in my car afterwards to leave, it was way below E. Then I filled her up, and the gauge was at the 1/4 mark. So that pretty much assured me that it was the guage and not a gas consumption issue. So, Jedi you’re saying the ground on the sending unit may be the problem? Its not stuck at E, it just doesnt read correctly. ---

No if the needle does not read period and just sits way under the E that it can be cause of loosing ground. as DTS said your sending unit itself is done and you need a new one ---

check the wires at the fuel sending unit, often everything rusts and messes it up, also if you did a walbro swap you might have messed up the wiring [Next page](https://forums.speedlife.net/t/fuel-guage/81422.md?page=2)
