Help with leaking fuel lines near the fuel filter

Hi,
Just recently I had noticed a leak at the fuel line connections in the vicinity of the fuel filter assembly.
Thought I'd head to the Parts division of my local VW dealer to look into replacing or even just finding out what's going on in that area
and why I have a leak already(40,000klm). Store person tells me that in order to have that rectified, you will need to purchase the entire harness
(around $1000 Geez). The store person then hinted to go across and chat with the service department because they have changed out a few of these in the past. Hmmmm.
Kindly enough and out of warranty the service department booked it in and it was found that there was some dirt around the connection that needed cleaning in which they did and sent me on my way.
Anyway, yesterday I have discovered that the leak is back and is worse.

I have searched the threads to see if anyone else has experienced this problem without any joy.
Has anyone had this issue and could they advise whether this $1000 fuel pressure/return line purchase should fail after 40,000klm?
Thank you in advance

    Not sure if it's been pressurised at that stage (been pumped), if not too much pressure use some silicone tape should solve the problem. If it's at the connector the doggy but effective way is to wrap around the connector with a thicker layer of polyurethane, once the polyurethane dries then wrap around with silicone tape it will form a strong and sealed mould.

    Just my doggy way that fixed the cracked fuel neck breather connector and works.......

    Or try get one from the wrecker

    Is it coming from the blue line, the black lines or the snap lock fitting?

    The black lines can be replaced easy and cheap, go to super cheap, bursons etc. Get x amount of 8mm fuel line capable of 100psi + and some worm clamps and replace it. Should set you back less than $50.

    No probs mate. I just did my secondary filter setup, all the hoses are easy but the hose clamps are a bitch! But since you're replacing the lines don't hesitate to cut the lines to make life easier for yourself. [MENTION=7099]Rawlings44[/MENTION] Google worm drive clamps for what you're looking for.

    Hey guys just came across this thread while looking for some info myself.
    Last Friday i how the same thing but much worse. Lucky i was near home.
    The tension style clamps at the "T" piece let go. Replaced them as required with regular screw style. Happy days i will be getting vw to sort out a more permanent repair. 3ec0bece2fa4a8619a3091238529f610.jpg2f3cd86f409bfdc138a51ab51bb732d9.jpg4b07c8b5f621bdece34386ccfb6f2ca8.jpg

    Mine now has the same fuel leak. Looks to be coming from around the T-Piece as well. Has everyone with the issue got a secondary filter? I figured it might be causing extra pressure.

    No mine didn't have a secondary it was just the tension clamp failure

    Gents, came across this forum when researching an issue I had in South Africa. Appreciate it's old but thought I'd post anyways.
    I was offroad in dunes and reversed over a small bush that snapped and sent part of the branch up and between the two front wheels. My automatic then "stalled" 100m down the road and when I opened the door and smelt diesel, knew there was a problem.

    Was absolutely amazed that there is no protection / plate / cover over the fuel delivery system as turns out the intake on the T piece snapped clean off.

    Was impossible to fix in the bush so had to be "recovered" and not easy doing this with no power steering or brakes as engine wouldn't run.

    Long story short, VW ZA do not import the T piece as a single part, you have to buy the entire assembly, which is **mad**! I found a generic metal T piece used in welding rigs and had them installed as have no doubt the ****ty plastic one will deteriorate over time.

    Here's a pic of the replacement piece and original part. Recommend replacing if you working in the area.

    Will be looking at fitting a protective plate as a real difficult issue to recover from in the bush.

    Regards

    I had my high pressure return hose crack up near the tank this winter after a -6.c night and had it replaced down at Anglesea autos for $457.
