Hi firstly thank you for any replies. I have air leak on low pressure lines suspecting the old primer pump return valve failure on 100,000. I have the new fuel loom. When I tried to take the first pipe off the car, fuel filter facing front of car I could not pass under the injector wiring harness, the black flat mat.Is the way round this to disconnect the wire to the injector and slightly lift up the mat to remove the old pipe and pass the new one through. My second question is about the pipe manifold is what I describe where there is two pipes going to the left of the engine facing forward into the car. The area where the third pipe goes, on the car I can see this goes to the return pipes. On the new one its just a nossle to accept the pipe. On the new one this is blanked off with what looks like pencil rubber.my question is do I leave this in or does it need removing so fuel can flow through. Thank you matt

Hello c3po03

I think you should take a few photos of the problem you are facing.

Then read up on this topic How to attach images to the forum

then you can post the photos and we can see what problems you are facing.

You have a diesel? Your 'Fuel Type' on the left (or above) shows a petrol :)

Hi matt

You want to fit the replacement fuel pipe set but can't disconnect all the pipes and get them off?

You can remove the all the fuel connections to the fuel filter and remove the filter.

It's a service item and should be changed regularly anyway, so it may pay to replace it with a new one anyway.

Hi it's just about the first fuel line it's disconnect ok but can not clear the connector under the injector wiring black matt. I am a bit concerned about disconnecting the wire to injector and lifting the mat up. Thinking of pulling the fuel line off the connector.This will solve the first problem.But how do I fit the new pipe in the same way as picture. Does it need to run under wire mat.

I am sorry, I don't know which one is the first fuel line.

Which bit is the 'mat'?

Pulling the fuel line off the connector doesn't sound like a good idea. If you have not taken off enough parts to get the old one off, you won't be able to fit the new one.

Just take off the parts you need to, take pictures, then refit them in reverse order, referring to the pictures you took.
Don't disassemble any connectors, unless its just to disconnect them in the way they were designed.

I would take all the pipes off, remove the fuel filter, and see if the pipe would come out, if I need to remove the filter carrier, I would do that too, and anything else that was in the way.

From the picture above its fuel line that runs under the wires that go to injectors the clip connector on the fuel line will not go back under the injector wires not enough clearance
