2003 Honda crv fuel gauge doesn't register full when filling up tank also twice while driving the gauge goes to empty and fuel light comes on


Could be the sending unit in the tank or the gauge on the dash.
A mechanic would test each component by disconnecting the harness at the tank.

How to adjust gas gauge to read right not reading way over filled like it does now. When 1997 chev 350 vortec truck gauge is at 1 st red mark close to empty, better not past gas station ! ! !


the fuel level sender is inside the fuel tank, part of the fuel pump assembly. did you or was the tank replaced before??they may have bent the float arm on reassembly . you can buy the sender from your parts supply store .you will have to drop the tank to do this it clips onto the side of the pump assembly. run it almost dry first as the tank is big n very heavy even 1/4 full. you can try to bend the old arm

but its very hard on the "sender" as for level indicator full to empty, think of the shape of the tank narrow at top to widest point in the middle (full to half) wide middle to narrow bottom( half to empty)

its just an overall volume thing

Repair is a major job involving dropping the fuel tank, a messy and dirty and dangerous job. It will take you at least one full Saturday to do this job if everything goes right and you have the proper parts. My free advice to you is to fill your tank every 200 miles and forget about the fuel gauge.

Fuel gauge registers full when filled with gas....drive 20mi and then drops to zero...still gas in the tank


The sender unit in the tank is the most likely cause. To test the panel unit, remove the wire from the fuel tank unit and gound it. The panel gauge needle should move up full scale to hot. Remove the wire from the ground and the gauge should return to empty. If this test is ok, the tank unit needs to be replaced.

My fuel gauge goes to full when i fill it but drops to E when i stop for something 83 ranger 2.3L


Sounds like it is time to replace the sending unit to the fuel gauge in side the tank. It registers until the fuel sloshes around in the tank and the movement causes the float to bounce around and then it shorts out the sending unit so it can 't register. The sending unit has two surfaces that must remain in contact to register. After years of moving around it develops play in the pivot point that causes a gap in the connection and thus a false reading. You will need to remove the fuel tank to accomplish this replacement. Remember be careful if you undertake this task. You will have fuel and vapor in the tank. Empty as much fuel as possible first.

Dashboard gauge


check the grounds on your fuel tank sending unit,must drop the tank to do this. with the tank down,remove the ground and look at your fuel gauge it should read full or empty,if it does not it may be a sending unit

Fuel Gauge not working


The switch that you use to change tanks is probably faulty - the switch supplies power for the sending unit in the tank, and to the transfer switch for the gas lines - use a meter to check it
