I will be reviewing the issue with the engineers as soon as they are in, however it may take a while longer for me to respond because they are out of the area.
I can say that overtigtening is easy to do on any of our kits when using a driver to tighten the hose clamps, never use a driver or ratchet to tighten hose clamps. Always use a flat blade screwdriver when the engine is cool to make adjustments and tighten hose clamps.
As soon as I hear back from the engineers I will let you all know, I appreciate your patience and I know it's been a weekend without answers (we do not work weekends) so I will do my best to post as soon as I have some answers for you as well as the OP.
