Good morning.
My 1990 1.6tdi Westfalia Atlantic has developed a leak.
The last few days I've been noticing puddles on my drive..I initially thought it was the waste water from the sink or a leak from the water tank but I had a look under the van last night and saw this.
It's on the drivers side (left hand) in the middle, the other side of water tank/gas box.
A constant drip...of diesel or mechanical fluid.
Can someone tell me what it is? Appreciate any help.
Thank you in advance.

Thats the fuel pipe return going into fuel tank, could just need a new rubber pipe onto the tank or the metal pipe end of the tank has rusted.

Thank you Multisi.
Appreciate your help.
