Disconnect the + cable from the battery.
Wear safety glasses.
Wipe the old filter and the fuel lines around it to remove any dirt etc.
Have a few rags available for some spillage. With the car off the fuel line is not under pressure. You will need at least 2 wrenches to loosen the flare nuts leading %26quot;in%26quot; and %26quot;out%26quot; of the filter.
Loosen and remove both fuel lines.
The fuel filter may be held in place as well with a clamp and you will need to remove the filter form this %26quot;holder%26quot;.
If possible depending on how the holder is designed it may be easier to reconnect the new filter and it's fuel lines before re-installing it into the holder. Be mindful of he new gaskets that may be included with the ne filter and be sure that the old gaskets are not still in place on the end of the fuel lines.
Re-install, tighten up, and double check your work.
Wipe up any mess possible left over from the fuel, allow it to sit a few minutes before connecting the battery back up.
Check work again, test start the car by turning the key on, wit 5 seconds to allow the fuel pump in the gas tank to apply fuel pressure then engage the starter.
It may not catch right away as the inside of the new filter is dry so you may have to repeat the previous starting step.
If you have any doubts, hit the local library and photocopy a page from a repair manual for you car regarding fuel filter replacement.
Good luck and no smoking during this job. :)
