Changing my fuel filter, what do i do?

tomorrow im changing my fuel filter, but i heard you have to relive pressure from the fuel system, how do i do this?

any tips/hints?Changing my fuel filter, what do i do?
Remove the fuel filler cap to release the vapor pressure from the fuel tank.

Place a flat pan under the filter to catch the fuel which will come out when the lines are loosened,use two wrenches ( one on the hex on the filter - the other on the line nut ) to loosen the fuel lines, Remove the filter mounting bolt/screw if one exists. Reverse procedure to install new filter. Re-tighten the fuel cap.

Turn the ignition switch to the ON position without cranking the engine.

Wait 10 seconds. Switch the ignition OFF for 5 seconds. This will operate the in tank fuel pump to prime the fuel filter.

Start the engine, it may stumble for a few moments as any remaining air is purged out.Changing my fuel filter, what do i do?
You relieve the pressure by taking the gas cap off. When you're done, just tighten the cap. Easy, right?Changing my fuel filter, what do i do?
When your car sits overnight or for a long period of time it will lose its pressure. Now when finished just turn the key on and off a few times to prime the lines.Changing my fuel filter, what do i do?
Near the air intake, the fuel line will usually has a fuel pressure test port. This port looks like it has a tire valve cap on it ( only the cap is larger ). cover or wrap this stem with a rag and depress the valve core. The fuel BUILT UP by the fuel pump will then bleed down. You should disconnect the negative battery cable from the battery before you start this job.
