1st General .Thanks to every body who replied to our problem while we were away.Problem has now been sorted it was the on board tank that was the problem.2nd Technical. I couldnt get a flo jet pump from our dealer with out placing an order £98 😱hmy: They had a Shurflo on the shelf at a bargain price so I have today fitted it to the van.I have to say the Shurflo when running is quieter than the flo jet but after the tap has been turned off pump runs on for about 3 seconds with a little knocking noise. I think it is Ok but. her Ladyship is not 100% happy hence this post.Once again thanks and I look forward to any answers to this one .I should have said is the over run and the knocking the norm on a shurflo pump
