Re: How do you replace a fuel filter in a 1995 chevy S-10...
You can use open end wrenches. just make sure the wrench fits well or you will round it off. i would use line wrenches if you have any. try not to tilt the filter when you get it off or it willl pour out.

Place wheel chocks behind the passenger side wheels, and lift
the driver side of the Blazer with a floor jack. Place jack stands
under the frame, and lower the vehicle
onto the jack stands. Supporting the truck with the jack stands in this
manner prevents injuries that occur if the floor jack fails.
Remove the fuel filler cap, and turn the ignition key to the
off position. This relieves some of the fuel pressure on the system, and
prevents the fuel pump from starting when the filter is removed.
Locate the fuel filter on the driver side frame rail, just
behind the front door. The filter is a cylindrical shaped part, about
six inches long, that's in the fuel line on the inside of the frame
Place a drain pan under the filter to catch any fuel that
spills. Loosen the filter fittings by using a 21mm wrench to hold the
filter while turning the flare-type nut on the line with a 16mm wrench.
Remove both sides of the fuel line from the filter and drain it into the
Check the rubber O-rings located on the fuel line ends for
tears and nicks. Replace any O-ring seal that shows damage. These seals
are available at your local auto parts store.
Insert the fuel lines into the ends of the new filter, and
thread the flare-nuts into the filter by hand. Be careful not to
cross-thread them and cause the need for replacement fuel lines. Tighten
both lines with the 21mm and 16mm wrenches.
Raise the truck off the jack stands with the floor jack, and remove the stands from under the vehicle. Lower the Blazer to the ground. Reinstall the fuel filler cap.
Turn the ignition key to the "Run" position--and then back to
the off position--three times to prime the new filter. Each time the
key is turned to the "Run" position, the on-board computer turns the fuel pump on and opens the injectors to add fuel for starting. Start the engine and check for fuel leaks.
A clean fuel filter in your Chevy means clean fuel injectors and a clean fuel pressure regulator. Replace
the fuel filter in your every 30,000 to 40,000 miles to keep
the fuel system in optimal condition. Follow the instructions provided
here to change the fuel filter on a Chevy that does not have a
flex fuel system. Difficulty: Moderate
Things You'll Need:
Container for fuel
New fuel filter
Disconnect the negative battery cable. Relieve the vapor
pressure in the fuel tank by slowly loosening the fuel filter cap. Wrap a
shop towel around the fuel pressure valve as you connect a pressure
gauge to the fuel pressure valve.
Put the bleed hose of the gauge into a container that will
hold the fuel. Open the gauge valve to bleed the system pressure. Drain
any fuel that remains in the gauge into the container, as well.
Raise the vehicle and clean the fuel filter connections and the surrounding areas.
Disconnect the fuel pipes and the threaded fittings from the fuel
filter. Cover the fuel pipes once they're disconnected, to prevent
contaminating your fuel system.
Slide the fuel filter out of the bracket on the frame rail.
Check the fuel pipe O-rings and replace the if you find any cuts, nicks,
or distortion. Slide the new filter into the bracket. Remove the caps
you put on the fuel pipes and connect the threaded fittings back to the
filter. Tighten the fittings to 18 foot-pounds.
Lower the vehicle and tighten the fuel filter cap. Replace
the fuel. Reconnect the negative battery cable. Turn the ignition on for
2 seconds. Turn the ignition off for 10 seconds, the Chevy and check for leaks.
Tips & Warnings
let the pressure out of the fuel system before you disconnect the fuel
lines. Do this carefully so as not to spray fuel on your skin, face or
Make sure you wipe up any fuel that may have spilled while you were replacing the filter.
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? Bob
Fuel Filter REPLACEMENT Gasoline Engines
The fuel filter is located behind the fuel inlet connection on the carburetor. On 1976–87 vehicles fuel filters incorporate a check valve and are not interchangeable with earlier years. Replace the fuel filter every 15,000 miles (24,135 km), or sooner if engine flooding is a problem.
Fig. 1: Hold the large fuel inlet nut on the carburetor while using a flare wrench to loosen the line connection
Using an open–end wrench (preferably a line or flare nut wrench), loosen the fuel line connection from the larger fuel filter nut. You will have to hold the other nut with a wrench to keep it from turning. Most of the time these units are quite difficult to remove. It is a good idea to apply a lot of penetrating oil to the threads and then tap the nut lightly.
Once you have the fuel line disconnected from the carburetor, remove the larger nut from the carburetor with a box–end wrench or socket.
Remove the filter element and spring from the carburetor.
Check the element for blockage by blowing through the fuel inlet end. If the element is good, air should pass through easily.
Once you have checked and/or replaced the filter, reinstall the carburetor nut and the fuel line. Be careful not to strip the threads.

79 is carbureted...There is a 5/8" nut fitting on the end of the fuel line at the carb inlet. Use a 1" wrench to hold the nut on the carb fitting and a flair nut wrench to remove the smaller line nut. Then remove the 1" one. The fuel filter is right behind the 1" one. Be careful to keep it straight when replacing it. The carb metal is soft and strips out easily. Don't loose any seal rings there either.
Disconect battery and releive the fuel pressure by opening gas cap and under hood with fuel pressure tester. then you need two open ended wrenches.. Go to driver side rear tire and just in front of the tire about a foot under the car you will see the fuel filter remove filter mounting bracket apply one wrench to filter nut and one to fuel line side and turn oposite directions, might want to spray with some penetrating oil fist to break loose, then remove plastic clip from other side of the fuel filter and it should come right out.
I REPLACED THE FUEL FILTER ON MY 1996 GMC JIMMY THE OTHER DAY. THE FILTER IS LOCATED UNDERNEATH THE DRIVERS SIDE INSIDE PART OF THE CHASIE.1ST DISCONNECT THE POSITIVE SIDE OF BATTERY, TO PREVENT ANY ACCIDENTS. THEN YOU JACK UP FRONT LEFT SIDE AND SECURE WITH JACK STAND.WEAR SAFETY GOGGLES BEFORE GOING UNDER NEATH THE VEHICLE. YOU WILL NEED THE FOLLOWING TOOLS; 20m,16m, and 13m OPEN END WRENCHES.TO BEGIN HAVE SOMETHING TO CATCH A LITTLE OF FUEL THAT WILL DRAIN WHEN YOU LOOSEN THE FUEL LINES.WHEN YOU LOCATED THE FUEL FILTER, TAKE THE 20m OPEN END WRENCH AND PLACE ON THE NUT FROM THE FILTER,THEN YOU TAKE THE 16m OPEN END WRENCH AND PLACE IT ON THE NUT FROM THE FUEL LINE THAT CONNECTS TO THE FILTER. BY HOLDING THE 20m WRENCH FIRM YOU REMOVE THE FUEL LINE NUT ON BOTH SIDES OF THE FILTER AS YOU LOOSEN THE NUTS FUEL WILL START DRIPPING FROM BOTH SIDES GIVE IT A MINUTE OR TWO .THE MOST THAT COMES OUT OF THE LINE WILL BE LESS THAN A CUP.NOW THAT YOU HAVE LOOSEN BOTH SIDES OF THE FILTER THERE IS A STRAP THAT SECURES THE FILTER JUST ABOVE THE FILTER,THERE IS A NUT THAT HOLDS THE STRAP YOU NEED TO GET A 13m SOCKET WITH A EXTENSION TO RATCHET AND REMOVE IT.LAST STEP FOLLOW THE FUEL LINE THAT GOES FROM THE FUEL FILTER TOWARDS THE ENGINE. THE FIRST CLAMP THAT YOU SEE HOLDING DOWN THE FUEL LINE TAKE THE 13m SOCKET AND REMOVE THE BOLT THAT HOLDS THE CLAMP NOW YOU CAN SLIDE THE FUEL LINE FROM THE FILTER.REMOVE THE FILTER AND BE CAREFUL THERE IS FUEL IN THE FILTER. TO REPLACE WITH NEW FILTER. REMEMBER TO LOOK AT THE ARROWS FLOW GO TOWARDS THE ENGINE
