What You'll Learn

Raise the back end of the vehicle and relieve pressure in the fuel tank
To raise the back end of your 2005 Buick Rendezvous, you will need to use a floor jack and jack stands. Place the jack stands securely on the frame, out of the way of the work area, but in a position to support the vehicle safely. Make sure the placement of the jack stands is stable and secure before going underneath the vehicle. Every year, people are injured or killed by vehicles that fall off a jack, so it is important to take the necessary precautions.
When raising the back end of the vehicle, it is important to use a level solid surface and chocks on both sides of the rear wheels. Soft ground, gravel, or other uneven surfaces can cause instability, so it is best to work on a paved, flat, and level surface. Ensure that the handbrake is fully applied and leave the car in gear or in park if it is an automatic.
Once the vehicle is securely raised and supported, you can proceed to relieve the pressure in the fuel tank. Start by loosening the fuel filler cap, which has pressure and vacuum relief valves built-in. This will allow any excess pressure to escape. If there is a significant release of pressure when opening the cap, it may indicate an issue with the fuel tank vent system or a malfunctioning fuel pump.
After relieving the pressure, you can continue with the fuel filter hose release process as outlined in the previous steps. Remember to exercise caution and refer to the vehicle's repair manual or seek professional assistance if you are unsure about any part of the procedure.

Loosen the flare type fitting on the fuel filter
To loosen the flare-type fitting on the fuel filter of a 2005 Buick Rendezvous, you will need to first relieve the pressure in the fuel tank by loosening the fuel filler cap.
Next, locate the fuel filter at the rear of the vehicle, on the frame, near the fuel tank. Place a drain pan under the fuel filter to catch any fuel that may spill. Using metric wrenches, loosen the flare-type fitting on the fuel filter. Be sure to use a flare nut wrench to avoid rounding off the flare nuts on the fuel lines. You can purchase these inexpensively at a parts store.
Once the flare-type fitting is loosened, you can proceed to release the quick-disconnect fitting on the filter by pushing in on the fuel line while squeezing the release tabs. When you hear the tabs click and release, pull the line off the filter.
From here, you can remove the bolt holding the filter bracket to the frame and remove the old filter. Insert the new filter into the bracket and start the nut on the flare fitting, but do not tighten it yet. Bolt the bracket and filter to the frame, and plug the quick-disconnect fitting onto the new filter. Push it into place until you hear it click.
Finally, tighten the flare fitting, lower the vehicle, and prime the filter by turning the ignition key to the "run" position for 2 seconds, then back to the "off" position.

Allow the fuel to drain
To allow the fuel to drain, you must first relieve the pressure in the fuel tank. This can be done by loosening the fuel filler cap. Once the pressure has been relieved, you can then loosen the flare-type fitting on the fuel filter with metric wrenches. Be sure to have a drain pan ready to catch any fuel that may spill. Allow the fuel to drain for a few minutes to avoid getting fuel on yourself while you finish removing the filter.
Safety is of utmost importance when working with fuel. It is crucial to take the necessary precautions to avoid any accidents or injuries. Ensure you are wearing the appropriate safety gear, including gloves and eye protection, and that you are working in a well-ventilated area. Never smoke or have any open flames nearby when working with fuel.
It is also important to properly dispose of the drained fuel. Do not pour it down the drain or into the ground. Instead, store it in a safe container and dispose of it at a designated location, such as a hazardous waste disposal site. Check with your local authorities or waste management company for the proper procedures and locations for fuel disposal in your area.
By following these instructions and taking the necessary safety precautions, you can effectively and safely allow the fuel to drain from your 05 Buick Rendezvous.
