Well i just wanted to know if this is normal. My gas gauge jumps around a lot. I get in my car today it said 3/4 right on the line. I drive down the block normally at 25mph go down a couple blocks i hit a red light so then i took a glance at my gauges to find my gas gauge going nearly 1/2 way point. so i keep driving and it stays around the 1/2 mark. I parked the car did some things i had to do checked back at the car is its back at 3/4.
I'm just wondering if this is normal. because this happens a lot to me. Its not like i floor it or anything its normal 15-35mph driving nice and smoothly. This has been getting to me for a while now just never thought much about it.
the whole in-tank unit has a floater, this raises and lowers according to the level in your tank... the sensor is in the intank unit as well. when the floater raises, the sensor reads the angle on the rod holding the floater... the sensor should be even (not too sensitive), so that it keeps an even read at all times no matter if you are hitting bumps or going up a hill or whatever... thats why when you fill up the gastank, the gauge goes up slowly, and not instantly... it might be a bad sensor if the level doesnt hold stable... see now...
oh ok now i understand about the whole in-tank floater but i don't think i can really fix this problem myslef. When i fill up at the gas station it does gradually go up for instants i just filled up from 1/4 so i drove back home about 15 min trip when i got home the tank was at 1/2. after about 4 hours i went back to just check on the tank and it was really near the 3/4 bar once again.
the floater is toying with me but i guess i can deal with it.
mine does it by about an 1/8th of a take only if i rev her up high for a little while .... the fule system in that car seems to be able to hold a good bit of extra gas when it increases pressure when the engine is running high ... also i think the gas goes back from the return lines and the pressure droping.... try drving granny style and see if it still does it
granny style hahaha.. funny thing is i did that today and i noticed it didn't move that much. was in the same place like a normal guage should but that was going like 25 mph always but then later i stoped then i noticed it moving up and down but not dramticly as before.
just wanted to post another incedent. well i felt like putting gas in my car for no reason today. It was right on the 1/2 line. Like literally. So i put in 4.5 Gals in the tank. assuming it to get to the 3/4 lines, which it did last time. I know the gas guage takes time so i didn't expect to see it go up anytime soon. but so i drove here and there picking up my daily things. i drove a total of 15 miles in a 3 hour time period. With pit stops and what not. So i look at the gauge, its didn't go up as a matter of fact it went a little lower. So thinking maybe if i let the car settle overnight when i return to it in the morning the guage would say 3/4 or near there.
woke up checked on the car and it was same a little under 1/2. whats going on. makes no sense to me. i'm scared that the gauge isn't reading properly like to the point where is will say 1/2 tank but i really have next to nothing. i'm just going to drop about 4 gals every week and see how that works.
This is something out of the blue and most likely wont really affected my gauge but if i did the fuel treatment thing, you think it might fix the problem?
mine is weird.. it goes down slower from full to 3/4 then it goes down faster from 3/4 to 1/2.. then lower than 1/2 it goes down slower..for example.. i drive to school and back with a full tank and i had to wait 2 days until it goes down to 3/4.. then after that, the next day i went to school and back and it went down to 1/2.. and it stayed there the next day (after i went to school and back) then it goes down to 1/4. it does that almost every week.
when i pushed the engine it goes down faster, but it goes back up after i stopped for a while..
so.. to be safe i always fill up when it goes down to 1/4 tank..
