Its not too uncommon for the lines to be extreamly tight due to corrosion and other factors...enough said.get some GOOD penetrating oil (not wd-40)spray it a couple of times throughout the day,let it sit all night and the most important thing is that you use the correct kind and size wrench you need Line Wrenches get a good one not a cheepo,the filter should have a 13/16 or so hex to put a good open end wrench and hold it as you use the line wrench on the line end.hope it works have a good day DB

Where do I locate the fuel filter on a 93 Chevy Blazer s10 Tahoe with a 4.3 votec engine?

It's attached to the frame underneath,right about where the driver's door ends,or slightly farther back.
If you're going to change it,first soak the fittings with some brand of penetrating oil,even WD40 if that's all you have. You need 2 wrenches on each end,probably 5/8 and or 9/16 (16mm & 14mm roughly) and try your best not to twist the fuel lines,rusty or not. They twist pretty easy that's why there are 2 wrench fittings on each end.
Good or bad,please rate my post?

Need to replace fuel filter

The fuel filter is mounted on the floor pan just in front of the fuel tank Use compressed air or carburetor cleaner to clean any dirt surrounding the fuel inlet and outlet line fittings. Once all the dirt has been removed, twist the two lines a quarter-turn in opposite directions to loosen the fitting. Depress the white plastic quick-disconnect tabs and detach the inlet line from the fuel filter (see illustration [see comment below marked "#2"] ). Note: Have spare rags or a small container to catch or wipe up extra gasoline that will spill from the filter assembly. Use an open end wrench to steady the outlet side of the filter and a flare nut wrench to unscrew the fuel line nut, then separate the outlet line from the filter while noting the installed position of the O-ring. Using a flare nut wrench will help to avoid rounding the corners off of the fuel line nut. Detach the fuel filter mounting bracket bolt and remove the fuel filter. Installation is the reverse of removal. Note: Be sure to install a new O-ring on the outlet line before reassembling. "Squeeze the white plastic quick-disconnect tabs together and pull the inlet line (A) away from the filter, then detach the outlet line (B) from the fuel filter - unbolt the filter mounting bracket to remove the fuel filter".

How do I change the fuel filter in a 1970 Caddy Fleetwood, 472 ci and where is it?

If you can locate where the fuel line goes into the Carb. Remove the fuel line then the larger nut behind that.The fuel filter is inside the larger nut.It is hard to try and get the fuel line off without both moving or twisting the fuel line,and most times there is not enough room to bend it out of the way to get the fuel filter out.If all else fails you can cut the metal line just leave a few inches back from the nut then when reinstalling you can patch it back with a rubber fuel line and clamps.You may also look into installing a inline fuel filter in better location.Well hope this helped.

How do you change the fuel filter. are there tools you use or do you just unscrew it and just pull it apart.

The filter is located under the passenger side directly under the door area.

Depend on the fuel system. if fuel injected, remove the fuel pump fuse, start the car. this will release the pressure on the pump. follow the gas line to find the filter, remove and replace with a new one. make sure you take the pressure off the system before you start. you could end up with a twisted fuel line and that is a bigger problem.

After done, replace the fuse, restart the car. it may take a few cranks to get it running. make sure the vehicle is secured on jack stands before you crawl under.. after the vehicle is started. check the entire lenght of the fuel line, for leaks. hope it helps. duboff. if not fuel injected, follow the fuel lines to the filter. some engines have the filter in the carb. it is a good idea to have gas line plug to prevent gas from running all over.

Removing original fuel filter on 96 grand am

if original, don't worry about the black cap and tabs on the non-threaded end of the filter connection. Unfortunately, you have to literally pull the heck out of it to separate it from this connection. What is holding it in is a metal "barbed" collared sleeve inside the connection. Try using a pliers on the cable side (don't bend or break!) and work the filter off using elbow grease. Not fun, but it worked. The FRAM replacement filter simply snapped right in.

Removing fuel filter

it takes a special tool to disconnect these lines. go to your local auto parts store and ask for the fuel line disconnect tool.once you have the tool put it on the fuel filter prong that the fuel line is connected to and slide the tool up into the gas line, at the same time pull the line away from filter. you may half to try this several times.also when the tool slides up into the line twist the line and push in and out. in short thare is a spring up in that line that gets stiff and corroted so moving the line around while the tool is in place helps free up this sprind.also spray a little lubracant in the ends of the lines before beginning.

due to the position of hte filter it is very tough but with the right tool every thing is possible so you have to get the tool a crow foot wrench i think it is 18mm and hold one end with a wrench and twist the ****** out of there if you feel the line is turning i would take it to a pro.
