I own a 1998 V70 AWD which is similar to the XC70. The XC70 is also all wheel drive requiring the rear cross member and rear differential be lowered in order to lower the gas tank. The fuel level sensor is mounted in the front of the gas tank and cannot be removed until the gas tank is lowered. The fuel level sensor is on the left side and the fuel pump assembly is on the right. This is a job best left to professionals as a vehicle lift and special equipment is required such as a lifting table and post jack to lower the rear end and the gas tank. I am a Volvo Technician and in the process of replacing a fuel pump in a 1999 XC70.
1997-2206 JEEP TJ Wranglers have the combination fuel pump assembly and fuel gauge sending unit located inside the gas tank. The gas tank needs to be unbolted and removed to access the fuel pump assembly.
Check engine water temp with a thermometer -- Replace temperature sending unit
Inside the fuel tank with the sending unit for the fuel gauge
Remove oil sending unit and replace with a mechanical gauge to check oil pressure
It's not fused separately. If your fuel gauge isn't working, you either have faulty wiring to the gauge, or a faulty fuel sending unit.
I believe that is Motorcraft DY961
Sounds like (& usually is) bad sending unit in tank.
Follow the main hose that goes from radiator to engine block. It is on engine block between the main hose connected to engine block and a pullye. The heat gauge wire is snapped on the sensor. Remove the wire and replace the sensor.
The fuel gauge on a 1998 Mercury Tracer may not work due to several potential issues, including a faulty fuel level sending unit, a broken connection in the wiring, or a malfunctioning gauge itself. The sending unit, located in the fuel tank, can fail over time, causing inaccurate readings. Additionally, a blown fuse or corrosion at the electrical connections can disrupt the signal from the sending unit to the gauge. Diagnosing the problem typically involves checking these components for faults.
Be sure you are replacing the temp sending unit for a gauge application. The parts counter person may have given you one for an idiot light.
Bad fuel sending unit in tank however it is part of the fuel pump assembly
The electric fuel pump is inside the gas tank with the sending unit for the fuel gauge
