Freelander 1 2004 TD4 2 door

Hello Everyone, and greetings from Kenya.

I recently bought an ex UK Freelander 1, TD4 2 Door. The diesel quality in our country is horrible (adulterated), and as a result, I found a lot of carbon deposits in the fuel system. All 4 injectors were completely clogged and had to be replaced (2 of them had to be removed using heat welding as they were stuck right in). I used a lot of information from this forum in finding and replacing the injectors. After replacing these, the car still had trouble starting, and was stalling randomly. The in tank fuel pump now has an issue and my mechanic has informed me that it will need replacement. The cost of this is quite ridiculous (although not as bad as the injectors), however, I need to get it done, and I need some help. Apparently, the in tank fuel pumps in the 2 door model are different from the 4 door model. With the 4 door being quite popular, the pump is readily available and quite cheap. The 2 door pump, on the other hand is really expensive and needs to be imported. My question here is two fold:
1. Does anyone have experience of a spoilt in tank pump, and is there a way to repair it? I am told that the pump is mechanically sound, however, the internal electronic component is not sensing correctly and therefore not sending the right amount of fuel to the engine. Is it possible to repair /replace just the electronic part?
2. Are there cheaper (albeit generic) pumps available for the 2 door model? I have seen the 4 door model pump, and it has 4 connector pins, whereas mine has 2 connector pins. Having looked through eBay (UK) listings, there are loads of new pumps with 4 pins available around the GBP 60 mark, however, there is no listing for a new 2 pin pump. I have tried to get the exact part number, however, it is not written anywhere on the pump (unless I am missing something?) and, I do not know if there is an online catalogue for getting part numbers using the VIN. I have attached a photo of the part.

PS: I am quite a noob when it comes to servicing cars and a lot of the terms being thrown around here. This was my first 'non-toyota' car that I serviced (at least partly). Please bear with me in case I ask for a further explanation. Thanks.

Would be very strange if the 2 and 4 door in-tank pumps are different. Are you getting confused with the wheel arch fuel pump introduced in 2002/3 which replaces the in-tank pump?

Having said that, I'm not sure how the pump could be "mechanically sound" but not delivering the right quantity of fuel. I'm wondering if the pump is fine but the O Rings have gone in the high pressure pump on the engine? When they go it can't regulate the fuel pressure and hence will not deliver the right quantity of fuel. They are very cheap/small (to post) to try before spending large on a whole pump.

Don't know what others think.

In my opinion the in tank pumps are the same, as you say depending on the year of the car the pump was replaced with wheel arch pump.

Also check the fuel filter again depending on age of car where it is situated in engine bay or rear OS wheel arch, check regulator O-rings cost is only £5.99 GBP link below

If the picture you posted is yours? It's not actually a pump. All that is, is a fuel level sensor and a strainer for the fuel.
The low pressure pump will be in front of the RH rear wheel. It's located under the plastic cover.

Yes, that is the picture. From some research, I have found out that it is the fuel pump & sender unit, which senses the level of fuel and is involved in pumping the fuel to the engine. Not sure how correct this is..

An 04 Freelander has two fuel pumps. A low pressure pump, mounted under the RH rear sill area. This pumps fuel to the engine's high pressure pump. The thing in the tank is simply the fuel level sensor. It has nothing to do with the fuel supply to the HP pump.
The HP pump can cause issues when low quality fuel is used. This is mounted on a front of the engine and driven timing chain.

The HP pump has a pressure control valve. As Arctic2 has said. The O ring can fail, causing starting and running issues.

What he said

Thanks for the response guys. I will check out the O ring, and replace it. Shall report once I have any feedback.
