Changing Fuel Filter In Jaguar X-Type: Step-By-Step Guide

Changing the fuel filter on a Jaguar X-Type is a relatively simple task that can be done at home without the need for special tools. The fuel filter is located near the right back wheel, in the engine bay behind the engine on the left. It is recommended to change the fuel filter every 15,000 to 20,000 km or every 12 to 16 months. When changing the fuel filter, it is important to relieve the pressure in the fuel lines first to avoid spills. This can be done by either wrapping a rag around a small screwdriver and pressing the schrader valve on the fuel rail, or by pulling the fuel pump fuse and cranking the engine a few times. Additionally, it is important to fill the new fuel filter with diesel before installing it. This can be done by using a syringe, a funnel, or a small nozzle from a tube of silicon sealant.

Location of the fuel filter

The fuel filter on a Jaguar X-Type is located near the right back wheel. More specifically, it is in the engine bay behind the engine on the left. It has three hoses attached to it. Two of the hoses have clips that slide out sideways, and the small hose has a clip that you squeeze.

Tools required

To change the fuel filter on a Jaguar X-Type, you will need a new fuel filter, a catch pan, and a small container. You may also need a rag and a small screwdriver if you want to discharge the pressure in the fuel lines before you start.

It is recommended to relieve the pressure in the fuel lines before removing the old filter, to avoid a mess. To do this, wrap a rag around a small screwdriver and press the schrader valve on the fuel rail, or pull the fuel pump fuse and crank the engine a few times.

The Jaguar X-Type fuel filter is located near the right back wheel. There are three hoses attached to the filter. Two of the hoses have clips that slide out sideways, and the small hose has a clip that you squeeze. There is also a bracket that the filter is attached to, which can be removed by popping off some clips.

When replacing the filter, note the arrows on the top of the new filter. Completely fill the new filter with diesel until it overflows. The fuel tank return (rear large hose) and the small bleed hose can then be replaced. The front large hose goes to the pump. Make sure that this is also filled with diesel and then clip it back on.

Discharging fuel pressure

It is important to discharge fuel pressure before attempting to change the fuel filter on a Jaguar X-Type. This is because the fuel lines are pressurised, and if you take off the filter without releasing the pressure first, a large amount of fuel will spray out.

There are two methods to discharge the fuel pressure. The first method involves locating the schrader valve on the fuel rail, which is the pipe connected to the injectors on top of the engine. It looks like a tyre valve, and you can release the pressure by pushing the pin in the centre—similar to letting air out of a tyre. However, some Jaguar X-Type models may not have a schrader valve. In this case, you can try the second method, which involves pulling the fuel pump fuse and cranking the engine a few times. The fuel pump fuse is located in the passenger compartment under the dash (#17 fuse) and not in the engine compartment fuse box. If the engine starts but stalls after a second or two, you have successfully released most of the pressurised fuel.

Once you have discharged the fuel pressure, you can proceed to change the fuel filter. The fuel filter on a Jaguar X-Type is located near the right back wheel. There are three nuts holding the filter in place, which you can remove without any special tools. When you remove the old filter, have a catch pan under the car to catch any fuel that comes out. Only a small amount of fuel will be released, about 2 ounces, so there is no need to worry about blocking the fuel lines.

Filling the new filter

Firstly, locate the fuel filter in the engine bay behind the engine on the left side. You will notice that there are three hoses connected to the fuel filter. Two of these hoses will have clips that slide out sideways, while the small hose has a clip that you need to squeeze to remove. Carefully remove these hoses, making sure to have a catch pan or container underneath to collect any fuel that may spill out.

Now, you can remove the old fuel filter by popping off the bracket that it is mounted on. There may be some clips holding the bracket in place, so be sure to detach them carefully. Once the old filter is removed, you can prepare the new filter for installation.

Before installing the new fuel filter, it is important to completely fill it with diesel fuel. One method is to use a funnel to pour diesel fuel into the inlet pipe until it starts to come out of the outlet pipe. Alternatively, you can use a syringe to fill the filter through one of the inlets at the top. Ensure that the filter is filled slowly and carefully to avoid spills.

Another innovative method suggested by a Jaguar X-Type owner is to use an old 2-litre plastic bottle (such as a Coke bottle). Cut off the top of the bottle, clean and dry it thoroughly, and then place the new filter inside. Fill the bottle with diesel fuel, ensuring that the filter is fully submerged by using a clean stick or screwdriver to hold it in place. Fill the bottle until the three connections at the top of the filter stop bubbling, indicating that the filter is full. Carefully remove the filter from the bottle, wipe off any excess diesel, and you're ready to install it.

Once the new filter is filled, you can proceed with the installation process, ensuring that the arrows on the top of the filter are correctly oriented.

Reattaching the fuel lines

Firstly, make sure that the fuel lines are pointed upwards and do not hang down too low. This will prevent fuel from coming out of the lines. You can also place a catch pan under the car to catch any fuel that may come out of the filter during the reattachment process. Only a small amount of fuel (about 2 ounces) is expected to come out.

To reattach the fuel lines, start by filling the new filter with diesel fuel. You can use a funnel or a syringe to fill the filter through the inlet at the top. Alternatively, you can turn the filter upside down, remove the drain screw cap, and fill it from the bottom. Make sure to put the rubber caps on the top inlet/outlet ports before filling.

Once the filter is filled, wipe off any excess diesel and proceed to reattach the fuel lines. The fuel lines can be identified by their size: the front large hose goes to the pump, the rear large hose is the fuel tank return, and the small hose is the bleed hose. Make sure that the arrows on the top of the filter are pointing in the correct direction when reattaching the lines.

Clip the lines back on, starting with the front large hose that goes to the pump. Fill this hose with diesel fuel before clipping it back on. Then, attach the rear large hose (fuel tank return) and the small bleed hose.

After reattaching all the fuel lines, you can start your Jaguar X-Type. It is important to note that if the car cuts out, there may be air in the system. In this case, do not keep turning the engine over, as air in the fuel pump can cause damage. Instead, remove the front hose to the pump, refill the filter and hose, and then try starting the car again.
