fuel gauge only showing half full

[wcolt45]

Any ideas on why my fuel gauge if at half when tank is full,well about 40 gal anyway,seem i read about this very subject here before but cant find it now.

Maybe a bad or mis adjusted sending unit ?

If you are sure about the ammount of fuel in the tank remove your in-tank fuel pump and check the float to see if it's working properly. Have someone move it up and down while you watch your gauge.

I have the same issue. I have started to just stop using the gauge and manually check the level with my yokes, but now might check the floats. Is it as simple as removing the fuel pump bolts and lifting up the unit??

That's better than it showing 1/2 empty! Most people don't worry about the gauge. No one trusts it anyway. Just ask Wreckerman for his opinion.

The only thing that lies more consistantly than a career politician is a deuce fuel guage.

Yes, once the pump is removed you can reach inside the tank and fiddle with the float. The float is seperate from the pump so it will remain in the tank.

Clean the wiper on the sending unit with a solvent. Or keep adding fresh fuel and drive it around until the fuel sloshes around enough in the tank to clean itself.

Mine eventually started working right just with a combination of those two.

i know that the needle in my fuel gauge sticks. sometimes it's stuck at 1/2, other times it goes up to 3/4. every now and again it makes it back up to 4/4.

i've flipped the switch on and off a few times and have watched the needle unstick from 1/2 and go higher.

I had to add another ground wire from the sending unit to the frame ground. Now works fine!!
