Gas gauge

Has anyone experienced this I am a new owner of a 86 Sammy, just pick up the truck last night, it has one third of a tank of fuel. I fill it up full, drive away and the guage says empty. On a side not if the gauge is now broken what is the average milage one could go on a tank of gas, I have stock sized tires.

Re: Gas gauge

I also have the same problem with my gas gauge!<font color=orange>Luigi, about the mileage per tank. My 88.5 with 31's gets about 195 miles per tank and my 92 with stock tires gets about 235 per tank. I'm not sure how that 4:1 t-case will effect your mileage.</font color=orange>

Re: Gas gauge

I believe you have a disconnected ground wire. I seem to recall that the fuel sensor is grounded where the tailights are. What happens is the zuk gets rear-ended, the tailight is replaced, but not all the ground wires are connected back. IMHO, I think it's because people ditch the side bumper caps and figure the "extra ground" (fuel sensor ground) is not needed.

Re: Gas gauge

food for thought,i remade both bumpers,move lights ect. starting at left rear of sami,i ran a #10 black ground wire to battery.i attached all lights to it.made a big improvement.gagues worked ,lights worked better,wiper motor even goes faster.life is good.remember negative is more important than positive in a neg. grounded system.ranger

Re: Gas gauge

Okay your problem is actally in the fuel tank sender . I had the same problem, went through checking the wires etc.
You will need to drop the tank to fix this. You will need to disconnect the fuel lines, fuel filller and the wiring.
take the sender unit out of the tank, and there should be a little cover over the pot for the sender. remove that
and you will see a little arm that should contact the potentiometer (The wires wrapped around the piece of plastic.)
You will need to lightly bend it in so the arm hits the pot as it moves all the way through it stroke. Once you are sure it
is making caontact all the time reasemble and away you go. it will take you 1-2 hours to do. just make sure you
have as little fuel as possible in the tank, do it in a well ventilated area and NO SMOKING while doing it.......
This is covered in most of the service manuals (a picture of the breakdown.) good luck. Did mine in Feb and has
been accurate since.

Re: Gas gauge

I think my problem might just be crossed wires after putting some miles on the tank the gauge is going up from empty to full...

Re: Gas gauge

Yea it will sort of work around 3/4 tank too. what happens is the armature makes contact sometimes. Check the
wiring first but my guess is still the sender.
