While working under my VW Transporter T3 fuel tank I unintentionally scratched it with the zip of my jacket.
Then I could smell fuel and saw a drop under the tank.
I touched it wondering where it came from and it started to drop more and more…
Ok… so under the dirt it was clear that my tank was leaking and that I had to replace it.
I bought a new tank (probably from China) from Ebay in Germany for around 120 Chf with shipping.
Good to know:
The filler diameter is different between -1984 and 1984+ models.
Replacing the tank is not that hard.
I did it on my parking lot. It should be much easier on a lift tho.
