As the inner metal fitting heats first (and expands) it crushes the hose against the clamp, which does not heat as quickly. As it cools, the crushed hose now has space for coolant to leak from. Later on, you notice the loose clamp and tighten it a little. The next time you run the engine, the process repeats itself. We finally switched to spring clamps and have not had the problem since. > > Terry Seaver > > > > -----Original Message----- > From: owner-europa-list-server@matronics.com on behalf of Paul McAllister > Sent: Wed 12/21/2011 2:44 PM > To: europa-list@matronics.com > Subject: Re: Europa-List: Coolant leak > > Hi Richard, > > It has been my experience that worm drive clips will ultimately leak due to > the thermal expansion & contraction from summer to winter.

At the time it did not occur to me to use constant tension clips (CTC). With that said, I used CTC's to solve a thermal expansion problem which is a little different to the issue I was having with my fuel hose. Many people may disagree with me, but of the few things I wish I had done differently in my build it was to have used all metal fuel lines. They are lighter and last forever.
