Replacing The Fuel Pump In Your Classic 1964 F600 Truck

Changing the fuel pump on a 1964 F600 is a complex task that requires a range of tools and safety precautions. Before starting, ensure your vehicle is on a flat surface, the engine is off, and the gas tank is drained. You will also need to stop the flow of fuel from the fuel tank by clamping the fuel pipe. The fuel pump has an input and an output, so you will need to disconnect both sides, remove the bolts holding the pump, and clean the engine block surface. When installing the new pump, pay attention to the alignment of the pump arm and cam, and be sure to use a gasket sealer to create a tight seal. Finally, reconnect the fuel lines, and you're done!

Stop the flow of fuel from the tank

Stopping the flow of fuel from the tank is the first step in replacing the fuel pump of a 1964 F600. This is a important safety precaution to prevent fuel leaks and accidents. Here is a detailed guide on how to stop the flow of fuel from the tank:

First, locate the fuel tank and make sure it is empty or close to empty. Siphon the gas out of the tank using a clear hose and an air pump. This step is crucial as it ensures that there is no fuel left in the tank that can leak out during the pump replacement process.

Next, identify the fuel pump and the connections to the fuel tank. The fuel pump is usually located inside the fuel tank, so you will need to find a way to access it. Look for the fuel lines, hoses, or pipes that connect the fuel tank to the engine. These lines will need to be disconnected later in the process.

Once you have located the fuel pump and the relevant connections, it is time to clamp the fuel line. Place a fuel cut-off clamp on the fuel line leading from the fuel tank to the engine. This will prevent any further fuel flow and reduce the risk of leaks during the replacement process. Make sure the clamp is tight and secure to completely stop the flow of fuel.

Now, you can proceed to disconnect the fuel line from the fuel pump. Depending on your vehicle's setup, there may be different types of connections, such as crushed (lemon) style clips or simple jubilee clips. Use the appropriate tool to carefully remove the fuel line without damaging the surrounding components.

After disconnecting the fuel line, there may still be some residual fuel in the system. Place a drip tray or receptacle underneath the fuel pump to catch any fuel that may leak out during the next steps.

If your vehicle has a fuel filter, you will need to disconnect it from the fuel pump as well. Cut or disconnect the fuel filter, being careful not to spill any remaining fuel.

By following these steps, you will effectively stop the flow of fuel from the tank, ensuring a safer and more manageable process when replacing the fuel pump of your 1964 F600.

Remove the connection to the fuel pump

To remove the connection to the fuel pump of your 1964 F600, you will need to first stop the flow of fuel from the fuel tank. These types of pumps work off a cam from the engine, so the pump will only move the fuel when the engine is running. As a precaution, clamp the fuel pipe to stop drips or residual fuel leaks. Use a simple screw-up clamp to squash the rubber pipe.

Place a drip tray underneath to catch any fuel that escapes. Depending on your setup, you just need to remove the connection to the fuel pump. There may be crimped (lemon) style clips or a simple jubilee clip. If you have a jubilee clip, you can undo it, but be aware that fuel may drip from the filter. If you have a clip that needs cutting, cut the rubber pipe to start the removal process. Once the pipe is disconnected from the fuel pump, there will be remnants of fuel that will run out.

The other side of the fuel filter can be cut or disconnected, whichever you prefer. The output side of the fuel pump should have a metal pipe that goes up to the carburettor. This is held in place by a nut and needs to be unscrewed. Be prepared for any remaining fuel to run out.

Next, remove the pipe from the output of the fuel pump. The fuel pump body is held in by two bolts. You can undo these in whichever order you prefer, depending on your setup and any parts that may obstruct access to the pump bolts.

Remove the output side of the fuel pump

To remove the output side of the fuel pump, you will need to prepare the following tools: a clear hose, an air pump, a car jack, jack stands, a flathead screwdriver, a 3/8" fuel line disconnect tool, and a 1/4 inch hex socket.

First, you will need to stop the flow of fuel from the fuel tank by clamping the fuel pipe to prevent drips or residual fuel leaks. Place a drip tray underneath to catch any fuel that escapes. Depending on your setup, you may need to remove the connection to the fuel pump by cutting or disconnecting the fuel line.

Next, locate the output side of the fuel pump. It should have a metal pipe that connects to the carburettor. This pipe is usually held in place by a nut that needs to be unscrewed. Be prepared for any remaining fuel to run out.

Once the nut is removed, carefully remove the pipe from the output side of the fuel pump. Note that fuel may continue to run out, so have your drip tray ready to catch any spills.

With the pipe removed, you can now access the fuel pump body, which is typically held in place by two bolts. You can choose to break both bolts free and undo them halfway to move the pump and determine the location of the fuel pump cam. This will help ensure that the cam is in the ideal spot when you reinstall the new fuel pump.

After locating the cam, fully remove both bolts from the pump and carefully take the fuel pump out of the engine block. Be careful not to let anything fall into the engine block, and properly dispose of any broken gasket pieces or debris.

By following these steps, you will successfully remove the output side of the fuel pump on your 1964 F600. Remember to work with caution and always place safety as your top priority when working with fuel systems.

Remove the fuel pump body

To remove the fuel pump body, you will need to first stop the flow of fuel from the fuel tank. This is because the pump works off a cam from the engine, so fuel will only move when the engine is running. As a precaution, clamp the fuel pipe to stop drips or residual fuel leaks.

Depending on your setup, you just need to remove the connection to the fuel pump. There may be crushed (lemon) style clips or a simple jubilee clip. If you have a jubilee clip, undo this. Otherwise, you will need to cut the rubber pipe to start the removal. Once the pipe has been disconnected from the fuel pump, there will be remnants of fuel that will run out.

The other side of the fuel filter can either be cut or disconnected, whichever you prefer. The output side of the fuel pump should have a metal pipe that goes up to the carburettor. This is held in place by a nut and needs to be unscrewed. Be prepared for any remaining fuel to run out.

The fuel pump body is held in by two bolts. Undo these bolts and remove the pump from the engine block. The fuel pump may have part of the gasket still stuck to it. Take care not to let anything fall into the engine block and be careful with broken gasket and debris.

Clean the engine block surface to ensure the gasket will make a good seal. Use a razor blade scraper, working away from the opening and working from the centre outwards. Use a degreaser on a lint-free cloth to wipe the surface down.

You can apply a thin bead of gasket sealer to one side of the new gasket. This will help to hold it in place, but be careful not to over-apply.

Reattach the input line of the fuel pipe

Now that you have removed the old fuel pump and cleaned the engine block, it's time to reattach the input line of the fuel pipe.

First, you will need to attach the input line of the fuel pipe to the male part of the fuel filter. Using a 'lemon' clip or a single ear clip with the correct tool will make it look neater. There will be a flow arrow for the direction of the fuel on the filter, so make sure the arrow is pointing towards the fuel pump. If you don't have the correct tool, you can use a jubilee clip to attach the pipework. Ensure that the rubber fuel pipe is not kinked and forms as straight a route as possible to the fuel pump. Place the tubing onto the male fitting of the fuel pump and secure it in place with a clip or a jubilee clip.

You could fill the filter with some fuel so that it is ready and primed. Alternatively, you can start with an empty filter, so any fuel you see in the filter has been pulled in by the pump itself when cranking over without starting the engine.

Now, reconnect the fuel line coming from the inner fender. Undo the clamp previously put in place to stop fuel from seeping and slip the new rubber pipe back over the fuel line.
