What size/type of wrench for screws?

If you go to the fuel pump in the front left side of the block you will see it screwed into the fitting on the pump with the other side the fuel line inlet from the tank spray the line in fitting with liquid wrench 2 or 3 times to make sure it is clean and lightly wire brush away corrosion and dirt to make sure that only the fitting turns and not the whole line when using wrenches one on the end of the filter fitting the other on the fuel line depending on how long that filter has been there you may have to saturate it a good amount and let it soak for up.to an hour or more once you are able to loosen the fitting only turning not the line twisting remove it then remove the filter use grease or antiseize lubricant on the new filter threads and tighten the filter housing into the pump if there is rtv sealant already on the threads you can put extra rtv to make sure it seals tight with no leaks without grease now go to the line fitting with some steel wool lightly rub away any dirt and corrosion you see and inspect the line for stability and conformity if it looks rusty it must be changed if not after cleaning put rtv silicone on the threads of the fitting and put grease on the line side of the fitting then slide it forward and install it into the fuel pump after tightening try to get as much grease around the line and push it into the fitting this will keep it from rusting and twisting on the next change of the filter that's it good luck stephen

The pump is electric, and it is inside the gas tank. You have to drop and remove the tank to change the pump.
The filter is a small metal cylinder, about fist size, and will be in the fuel line under one side or another of the car, unless it is in the engine bay, just before the fuel line reaches the engine. I expect it would however be underneath, along a frame rail. Just follow the fuel line from the tank. Both ends of the filter are threaded. Use 2 wrenches, one as a back-up while you loosen the fuel line fitting. Be careful of damaging the end of the fuel line-that is why you want 2 wrenches.

You will need to drop the gas tank to get to the fuel pump just hope it's not full or it will b quite heavy

The fuel filter is under the car near the fuel tank (see diagram below). It's a canister with a fuel line threaded into both ends of it. You will need a 20 mm wrench to hold the filter and a 16mm line wrench to loosen the line fittings. You may also be having an ignition problem. All ignition components are under the aluminum top engine cover.

Instructions Things You'll Need:

• Jack
• Safety stands
• Wrench
• Socket wrench
• Pliers
• Screwdriver

1. 1 Jack up the car and support it with safety stands. Be sure the car is high enough to get the tank out from underneath the car. You could use a car lift instead. If you use a lift, you will need an automatic transmission jack or a second person to help you lower the tank to the ground.
   
2. 2 Unclamp and remove the filler and vent hoses from the gas tank. Most are held on with aero type hose clamps. Unplug any wiring to the fuel pump and sensors. Using wrenches or pliers, remove the fuel lines at the pump. You might need to lower the tank one to two feet to remove the lines and wires.
   
3. 3 Support the gas tank with the jack. Use socket wrenches to unbolt the gas tank straps. Remove or reposition the straps out of the way of the tank. Lower the tank some and check to make sure all lines, hoses and wires have been removed. Continue lowering the tank and place it on the ground.
   
4. 4 Clean the tank area around the fuel pump assembly of all dirt and debris. Release the pump assembly retainer. This may held to the tank with a clamp, a slip ring or screw nuts. Remove the pump assembly from the tank. Drain any liquid fuel from the assembly and place on a work bench.
   
5. 5 Remove the pump from the assembly and discard or replace the entire assembly. Some pumps can only be replaced as a unit. If you can replace just the pump be sure to install the new sock filter that comes with the pump.
   
6. 6 Return the repaired pump assembly to the tank. Use new gaskets or O-rings if supplied. Secure it into the tank with the retainer.
   
7. 7 Place the gas tank back onto the jack and raise it to the car. Reinstall the fuel lines, hoses and wiring. Continue raising into its cavity on the body. Secure the tank with the gas tank straps and tighten with a socket wrench.
   
8. 8 Reinstall the filler and vent hoses. Tighten the clamps. It is a good idea to also replace the fuel filter at this time. Lower the car to the ground. Test for leaks and repair any found.
   

it is located at the inlet to the carberator, below is most common one for the 302 V8

The fuel filter is located near the rear of the vehicle, forward or rearward of the fuel tank, depending upon application. There is no service interval for fuel filter replacement. The filter only is replaced if it becomes restricted.

REMOVAL & INSTALLATION Relieve the fuel system pressure at the shrader valve on the fuel rail. For details regarding this procedure, please refer to Fuel System of this information.

1. If not done already, disconnect the negative battery cable.
2. Raise and safely support the vehicle.
3. Clean both fuel feed pipe connections and the surrounding areas at the in-line fuel filter with a clean rag to avoid possible contamination of the fuel system.
4. Using a backup wrench, remove the fuel line fittings from the fuel filter. Most of the models fuel gilter wrench sizes will be 16mm and 20mm.
5. Either disconnect the quick-connect fittings by pushing inward toward the filter and grasping the plastic tab around the connector and pull them apart. Or remove the fuel filter mounting screws, then remove the filter from the vehicle.
6. Discard the fuel line O-rings and replace with new ones during installation.

To install:

Install new O-rings to the fuel line fittings.
Connect the fuel lines to the fuel filter.
Position the filter in the same position it was during removal. Using a backup wrench, tighten the fuel lines to 20-22 ft. lbs. (27-30 Nm).

1. Install the fuel filter mounting screws if used.
2. Lower the vehicle. Install or tighten the fuel filler cap, then connect the negative battery cable.
3. Start the engine and check for leaks. Turn the ignition switch to the ON position for two seconds.Turn the ignition to the OFF position for ten seconds. Turn the ignition to the ON position. Check for leaks.

Location of the fuel filter


Unfasten the retaining bracket can make removal of the fuel filter easier


Either use a clean rag or compressed air to clean the surrounding areas of the filter


Use a backup wrench to disconnect the fuel line fittings from the filter


Disengage the quick-connect fittings, then remove the filter from the vehicle


In-line fuel filter mounting and related components

It sits in front of the fuel tank.

Step 1-Determine type of fuel line to be replaced. Rubber hoses will have clamps on both ends that should be loosened with screw driver. Nylon and steel lines will have a ferrule at both ends removed and replaced using proper size line wrench

Step 2-Using proper size line wrench or screwdriver, loosen fittings by turning counter clockwise. Catch fuel remaining in lines in a gasoline safe container.

Step 3-Remove defective fuel line and install the new line or hose opposite of removing. Take care not to strip or cross-thread fittings as this will cause leaks.

Step 4-Dispose of remaining fuel in an OSHA safe container.


hope it helps-

You'll need brake line wrenches, this will help you to prevent stripping the heads on the break line screws. Also it depends on whether you are making your own break lines or you are already buying the pieces premade (which I advise doing if you have never flared lines before). Before actually going to get the parts I would take all lines off that need to be replaced, this way you will know exactly how much you will need. This will also help you know the size line and what type of of threading you will need on the ends. I would follow all the lines before taking the tank out, you can sometimes by pass this. Please post more info after you have gotten that far and I'll be sure to follow up. Brake lines and brakes are kind of my speciality.
