Hi. I'm new to the forum and hoping someone in the know can advise. I have recently caused damage to the top of the fuel sender unit by accident on my 2004 Freelander td4 HSE. Whilst refitting the sender and pushing down hard to fit the locking ring I accidentally snapped the short plastic tube around 8 mm dia that comes from the top of the sender at 45 degrees. I have managed to make a temporary repair. There is a rubber pipe that fixes to this tube with a spring clip. Can anyone advise what this pipe is for? There are the usual inlet/outlet pipes that fix horizontally and a small dia pipe for the fbh. Any advice is appreciated.
