Brambles Posted May 31, 2017 Share Posted May 31, 2017 I suspect your in-tank pump seal is leaking or the vent pipe which runs from it up to near the top of the fill pipe. A case of accessing the pump and check for leaks, there will be plenty of staining showing where it has been leaking from. Link to comment Share on other sites More sharing options...
monique.hubrechtsgm Posted June 1, 2017 Author Share Posted June 1, 2017 My fiat dealer said that in my case of a burstner integral motorhome non-fiat connections are applied to fiiller fuel tube. And that connection is leaking. Most likely not the breather tube. Burstner dealer shoud check first. He is 99 percent shure about this. The problem do not exist when tank is not full. Will check whit burstne what their modificatios are. And how to hanldle. Keep you informed about this. Link to comment Share on other sites More sharing options...
