Hi, I'm new to this caper (forums). I have a D22 with a 150L Davis tank. It sprung a leak on my last 4WD (fairly severe) trek. It appears that the rear edge of the tank has been rubbed for many years by the tailshaft (suspension movement?) and finally broke through. Soap and then a self tapper with neoprene washer got me home (500Kms). The tank is still not leaking (yet). Has anybody else experienced this and is it a faulty design of the tank? A minor modification to the tank shape would solve the problem, I would presume. The tank was fitted 8 years ago, so the problem will take years to be detected. The wear seemed to be very slight and gradual. Is there a possibility of seeking redress from the tank manufacturer?
