Hi, i was hoping someone can tell me how the fuel sending unit works electrically, because i just took out my gas tank to fix the unit, and there is a wire on the unit that is cut off, wondering to what?? or is it just a ground, just for safty, because of fuel, im asking where this wire belongs. thank you.

Well Sarah, the fuel sending unit is built onto the pump, which is located in the tank. It is common for a tooth to break off of the reastat (sp) part of the sending unit. You will have to replace the pump assembly which requires dropping the fuel tank. Hope this helps, TJ
Hi, the problem is in the sending unit located at your gas tank. I believe it is on the top of your tank, and you will need to remove either the rear seat to get to it, or what ever is directly over the tank. It may have a bad wire connection at the float assembly and sending unit that tells your gauge the amount of fuel is in the tank. If you are not sure, pick up a manual at any auto parts store, Chiltons, Haynes which will guide you through it.Your gauge is OK, it will be the sending unit that tells the gauge. I wish you the best on this, Shastalaker7
not too bad as long as you lines and straps are in good shape. dis connect battery first. you will need to remove fuel filler tube, electric connector fuel lines and vent line , un- do tank straps. you need to get the car up high enough to drop tanks and helps if you have someone to muscle the tank up and down with you. hope you do not have much gas in tank. also do not try to clean sending unit. just replace it. you do not want to do it twice. take care not to break any wires of fuel lines.
sounds like its time for a new sendinding unit, this is the part that hold the fuelpump inside the tank, and has a float arm, this is what tell you how much gas is in the tank, heres a picture of it,this comes with everything even the pump,also make sure to wire in the new connector,these trucks have connector problem,good luck.also check the ground that go to that connector, follow them,may go to rear frame on the leftside, remove and clean them.
Well that tells me that someone installed the wrong fuel level sensor. Your going to have to drop the tank and pull the pump and float assymbly out. Then go to a parts store and get a sending unit that has the opposite resistance of that sending unit. Just wait until the tank is empty so its a lot lighter. You can call the parts store or go down and see if there is multiple sending units. The sending units work by resistance, when the tank is full the float moves up and turns a wheel in the sending unit, which either removes or increases the resistance causing the gauge to lower. The sending units either give full resistance at full or no resistance at full and then changes as the level goes down until it does the opposite at empty.
HI, the gas gauge sending unit is located inside the fuel tank. it is part of the fuel pump assembly. you will need to lower the tank to access this sending unit. replacing the sending unit will fix this issue.
It could be a couple of things it could be your sending unit. a bad wire. or possibly the gauge its self. but the bad thing is you have to take your gas tank down to check the wires and sending unit. if you take the tank off you can pull out the fuel pump and sending unit and use a ohm meter to see if the sending unit is reading all the ranges correctly hope this helps you out
