Fuel leak - any help appreciated

[Tom_IK]

Evening all, today I noticed after moving the van around 3x nearby parking spots that they all had a small spot of what I thought was oil on the floor. After further investigation unfortunately it hand come from my T6 and it was in fact Diesel.

I have had a look underneath the van & the entire fuel tank seemed to be covered in fuel however no obvious location for the leak. The staining seems to be quite high leading me to believe that it could be coming from above the fuel tank.

After looking through threads on here people have identified issues from their diesel heater pipes however I do not have one.

Has anyone had any experience with this issue that they could kindly share?

Thanks in advance.

Tom

Did you ever find the cause of this? I have pretty much the same and can’t see anything obvious yet

As with most leaks, completely de-grease and then monitor, you’ll then find the exact location.

@Tom_IK @JPMUSTILL - did either of you figure out your leak? ill add myself to this little gang. I've dropped the tank twice now, the first time I assumed diesel heater pipe, so removed it/capped it off temporarily, however a while later it returned. I dropped it again today and replaced the diesel pipe, but after a good clean down I'm not seeing any leaks whilst running (I left the truck running whilst the tank was lowered to try and identify the cause). I'm beginning to wonder if its the filler neck or breather pipe, perhaps when the tank is brimmed? I'm going to put half a tank in tomorrow and monitor.
