Have a tank reproduced no longer to reason and to get? In Poland, for example? That seemed like a good plan. And only a little later than agreed, a completely new copy was returned.
Then the reborn classic started inexplicably hiccups when the tank was less than 3 / 4 full.
To a heeeel make a long story short: In Poland, the old tank was sharpened to use the halves as a model. Everything was measured and measured. The Poles made something beautiful out of it: the perfect replica.
They had only forgotten when measuring the thickness of the grinding wheel weaarmee the tank was halved. As a result, the fuel intake pipe came just too close to the bottom. With an almost full tank, the weight of the gasoline pushed the bottom slightly down. When the tank became more and more empty, the bottom 'lifted up' a bit… And the fuel supply was virtually closed off.
