Thread: new 90 leaking fuel tank

I would keep an eye on it but chances are you just overfilled it. The tank breather pipe is just above the top level of the tank and the fuel filler is at a higher level, so when it is overfilled any fuel above the level of the breather exits through it. There is a mod to extend the breather pipe up to behind the light clusters to stop this happening.



Number 6 in the above pic is the breather pipe. Also after playing in mud this breather pipe can become unclipped and will droop down lower.

Filler pipe and connections worth checking.



HTH Brian.

I recently had a blocked breather filter. The car had done 40K. I filled the tank and drove 100klm back to camp so it wasn't my usual chokers full. Overnight it started dripping and created a diesel shadow around the lower fill port and on the chassis. To me it looked like it had split the tank in that area as it was dripping reasonably well.
Next couple of fills nothing at all happened. Dealer said they found a blocked breather filter and replaced it. Still nothing again, seems sorted.

Nugget has some experience as well similar to yours. Check his post in members rides

I have had the same problem. The dealer told me it was because I crushed the breather when 4wding. The breather pipe is 8mm I extended it using oil resistant plastic hose and a stainless 8mm push in hose connector when fitting a long range tank.
