fuel sending unit

good afternoon forum. just here fiddling with my cj. i've noticed that when i fill with gas the gauge reads about 1/8 lower than it should. it's a 20 gal. tank and im going off how many gallons i put in it. i've already ran a solid ground from the sender to the dash.it got a little better but still dosent seem to read correctly.if i bend down the float on the sender will it change anything? just asking before i go drop the tank again.i even ran it to empty and it ran for about 2 miles before i ran out of gas. should i leave it alone beacuse it bugs me in the back of my head to know i fill up with XX gallons but it shows lower. sorry for the long story but hopefully someone will have a quick fix. thanks in advance

Re: fuel sending unit

Neither of mine work as well as you describe, at least you get some idea how much gas you have. Take it wheeling a few times and I'm sure it will stop working.

But here's a link to John Strenk's Gauge pages (thanks John).

<u>Gauge Quick Test</u>

This is likely linked in the page above:

<u>Basic Troubleshooting for CJ gauges</u>

Re: fuel sending unit

well i guess i should be happy it marks at all but it's driving me crazy just knowing it's not accurate. so how about bending the float arm or a new guage? thanks for the links. i had already went through those.

Re: fuel sending unit

How is everyone this evening?
Anyway I have an 88 YJ and I seem to have a bobblehead fuel guage. It bounces around and it's kind of hard to tell how much fuel I have in the tank (although it gives me a general idea) Does anyone know what causes this? should I replace the float and sender in the tank?

Re: fuel sending unit

As far as I can tell, most of the 88 YJ's do the bobble head thing...Ignore it, it's better than most CJ's, we have it good. Just remember, when the needle stops moving...you gotta get gas NOW!

Re: fuel sending unit

I cant Ignore it, I'm not the type. I have to fix it. I dont think that they came that way new so there must be a way to make it work right. My goal is not to make it the way it was when it was new but to make it the way it should have been. when I find the cure I'll post it.

Re: fuel sending unit

I bought my junk when it was 2 years old and had 12k miles on it...it did it then...still does it. I'd rather spend my time wheelin' than try to track down that little gremlin. [img]/ubbthreads/images/graemlins/grin.gif[/img]
