Just found a petrol leak, which part is this?

Hi all,
whilst testing my split charge i've just found a petrol leak on the van!
anyone help with what the part is or the likely culprit in this area?
i've put a video and a few pictures to save lots of questions so excuse the stupidity but it makes it easier to diagnose with more to see.






the pic where it's dry is with the engine stopped
the other 2 are engine running.

video to just show the location in relation to other parts.

to clarify i have not changed any fuel lines as they all look ok and this was on my jobs to do over the winter list.
Cheers if you can help.

 

I think thats the fuel pressure regulator thats leaking:

Part number 3 on here:


Get those fuel lines replaces ASAP. They probably look OK on the outside but breakdown inside.

 

Not sure if this is the same part but vwheritage sell them:

ok guys cheers thus far, i know i really need to do the fuel lines i was waiting until the winter lay up :-[ looks like i've had a lucky escape, i was/am going to drive to blackpool on friday.....seems my leisure battery went flat for a reason causing me to check the relay and see this......i'll watch te grand prix and have a look later or maybe monday night.

 

Yeah, as they say change the lines, its not a mahoosive job and will give you piece of mind now that you've seen the leak. and after all its what sundays are for F1 then tinkering

 

suppose so, has anyone got a link to a decent fuel line supply kit? i know people go aircraft grade etc, but what options are there?, i wanted to wait until the winter lay up really and do the tank filler one and that is a bit of a pig isn't it? i did have a expanded diagram saved on the old site but it's gone now.

 

all it says to me is if it isn't clamped i'm running with 33 year old fuel lines............. i can't see that being possible? i'm gonna look later for deffo but it's a scary thought. i've not heard of the site you say but i'm sure they are google able...

presume you mean these?

 

the FI engine that i rebuilt recently, i replaced it all with this

really nice, 250psi burst pressure

and i can't believe that vw never fitted fuel line clamps to a system that was running at 3 bar pressure

 

isn't 8mm to big? i thought 6mm was the limit?

 

8mm for FI, 6mm for carb engines

Like I said, I just rebuilt a 2L FI engine for a van and replaced all of the fuel lines

The engine in question..
