Replacing The Fuel Pump In Your Classic 1957 T-Bird

The fuel pump in a 1957 T-Bird can be challenging to replace, and there are a few things to keep in mind. Firstly, it is recommended to replace it with a reputable electric pump to avoid common issues with defective new replacements. Secondly, accessing the fuel pump may require removing or loosening certain parts, such as the power steering support bracket or the power steering assembly. Additionally, specific tools like fuel pump removal tools and socket sets of various sizes may be needed for the task. When purchasing a new fuel pump, it is important to consider factors such as pressure rating, voltage, and flow rate to ensure compatibility with the T-Bird's engine.

Removing the power steering support bracket

To remove the power steering support bracket as part of the process of changing the fuel pump on a 1957 T-Bird, follow these steps:

Firstly, loosen the two adjustment bolts that are holding the PS pump onto the bracket. This will allow the PS pump to be pushed forward, creating enough space to get the fuel pump past it.

Next, remove the bolt from the exhaust manifold and then the two bolts from the bracket itself. This will allow you to completely remove the support bracket.

Once the support bracket is loose from the manifold, the rubber hoses will let you push it up beside the fan shroud and out of the way.

With the pump out of the way, you can finish painting the cast bracket engine colour.

It is also recommended to have the engine at TDC (Top Dead Center) when re-installing the fuel pump, so the actuating cam is as far up as possible.

Disconnecting the fuel pump

Next, remove the power steering support bracket. Loosen the two adjustment bolts holding the power steering pump on the bracket, allowing it to be pushed forward and creating space to access the fuel pump. If necessary, you may need to remove the entire power steering assembly for better access.

Once you have sufficient access, proceed to disconnect the fuel pump by removing the rubber inlet hose and the steel line that connects the pump to the carburettor. These fuel lines can be challenging to reach, so a combination of tools may be required. A 1/2" socket is typically needed for the bolts. Take care when backing out the bolts, as there won't be much swing due to the confined area.

After disconnecting the fuel lines, you can now focus on removing the fuel pump itself.

Getting the old fuel pump out

To get the old fuel pump out of your 1957 Thunderbird, you'll need to first disconnect it. Then, you can try to remove the Power Steering support bracket, as suggested by one Thunderbird owner, which should give you enough room to remove the old pump. However, if that doesn't work, you may need to remove the whole power steering assembly, or try passing the old fuel pump through the bottom of the car.

Another Thunderbird owner has suggested a different approach. They recommend loosening the two adjustment bolts that hold the flat steel PS pump mounting bracket onto the casting that bolts to the water pump. This will allow you to twist the PS pump counterclockwise, creating enough space to lift the fuel pump out.

If you're working on a 1965 Thunderbird, one owner has suggested that you can access the fuel pump from underneath the car, although it will take some time and a combination of tools. They recommend raising the car on jack stands to get better access. Start by removing the oil filter and then the filter adapter from the block. This will give you access to the fuel pump, and you can then remove the rubber inlet hose and the steel line to the carb from the pump.

Remember to take your time and be careful when working on your Thunderbird, and if you're unsure, it's always best to consult a professional or seek further advice.

Choosing a replacement fuel pump

When choosing a replacement fuel pump for your 1957 T-Bird, there are a few things to keep in mind. Firstly, it is recommended to avoid the current crop of new replacement fuel pumps, as some users have reported that they are defective, with one user specifically mentioning those from China. Instead, it may be a better option to get your old pump rebuilt, or opt for a reputable electric pump from brands like Edelbrock, Holley, or Napa.

When considering a replacement fuel pump, it is important to ensure that it is compatible with your T-Bird's engine and fuel system. Check the pressure rating, voltage, and flow rate of the pump to ensure it matches your vehicle's requirements. For example, the Delphi Automotive Fuel Pump, which offers a mechanical fuel pump with a pressure rating of 6 psi, a voltage of 12V, and a flow rate of 25 GPH, may be a suitable option.

Additionally, consider the type of fuel pump that will work best for your T-Bird. There are two main types of fuel pumps: electric and mechanical. Electric fuel pumps are often more efficient and reliable, while mechanical fuel pumps are typically less expensive and simpler in design. It is worth noting that the original fuel pump in the 1957 T-Bird is a mechanical fuel pump, but you can choose to replace it with an electric one if you prefer.

Furthermore, pay attention to the warranty offered by the manufacturer. Some fuel pumps come with a limited lifetime warranty, which can provide added peace of mind in case of any defects or issues. It is also beneficial to read reviews and seek recommendations from other T-Bird owners to ensure you are choosing a reliable and trustworthy brand for your replacement fuel pump.

Reinstalling the new fuel pump

To reinstall the new fuel pump, you will need to ensure the engine is set to the top dead centre mark on the crank pulley. This will ensure that the eccentric cam that operates the fuel pump is on the low side of the cam, reducing pressure against the operating lever.

Next, insert the new fuel pump arm into the opening, sloping it down to get it under the cam eccentric. If the eccentric is in the lowest position, you may need to use a remote start switch to bump the engine until it moves to the up position, reducing tension.

Once the arm is in place, replace the rubber hose and use car starting tread on the inverted flare nut on the steel line. Make sure to use gasket cement for the gasket to pump, and automotive silicon sealer for the pump to block, which will make clean-up easier if you need to redo the job.

Finally, prime the pump, start the engine, and check for any leaks.
