How to Empty the Fuel Tank

Model: (Various brands) Various
Part: Checks and maintenance

Video tutorial

Sometimes it may be necessary to empty the fuel tank, for example, in the case of incorrect refuelling (petrol instead of diesel or vice versa). If you want to avoid removing the tank and do not have a siphoning pump available, you can proceed as follows.

Open the bonnet, connect a rubber hose, one end to the pipe through which the petrol flows to the engine, and the other end to a sufficiently large container. Locate the fuel pump relay in the fuse box and power it with a jumper to activate it.

How to Remove the Rear Seat of a Hyundai Tucson?

To remove the rear seat of a Hyundai Tucson, follow these steps. Start by moving the front seats to their most forward position to gain space. Next, locate the release lever on the underside of the rear seat, near the floor. Press this lever down while pulling the seat upwards to unlock it from the anchor pins. Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat. Be careful of any electrical cables or components that may be connected to the seat during removal. Once the rear seat is removed, the disassembly is complete.
