Installation instructions of fuel level sensor gauge

Step 1: open the fuel filler of the fuel tank, observe or test the approximate position of the sensor and the internal partition of the fuel tank with a stick.

Step 2: determine the position of the hole. The hole should be far away from the fuel filler, the sensor of the original vehicle and the internal partition.

Step 3: drill a 10mm diameter hole on the mailbox with a 10mm drill.

Step 4: use iron wire to penetrate through the 10mm hole and out of the oil filler to guide the sensor.

Step 5: put the sensor into the oil tank from the oil filler, and clamp the wire harness end of the sensor with iron wire. It is important to ensure that the sensor does not fall off.

Step 6: apply diesel resistant sealant around the small hole to prevent oil leakage.

Step 7: screw on the big nut. If the sensor rotates with the nut at this time, fix the notch on the threaded rod at the top of the sensor with an open slotted screwdriver, and continue to tighten the screw with a 12 inch hand.

Step 8: wiring.The one on the left is the self-contained harness of the sensor. Brown is the sensor power supply, connected to the GPS host 5V (connected to the GPS brown line), black is the ground connected to the negative pole of the GPS host (connected to the GPS black line), and blue is the fuel signal line (connected to the GPS purple line). The line on the right is the line extending from the GPS host to the sensor, which passes through the small hole on the side from the outside of the nut into the inside of the nut. Note: the extension wire is inserted from the outside to the inside through the hole. After the internal wiring, the wire is wound into the screw. After connecting the three connectors, seal the small hole of the incoming line and the top of the sensor with 704 sealant, and then gently lift the line and place it inside the nut.

Step 9: apply some sealant on the sealing part.

Step 10: tighten the cap so that it cannot be opened with bare hands.

Step 11: arrange the harness and complete the installation.
