There are a LOT of RV14's with the transducer in the stock location, and this is the first I've heard of this happening. If this is correct, the wiring is farther away than the supply hose---so even though its firesleeved, there may be some heat indications on the very edge of the end of the sleeve (even though end dipped) or slight discoloration of the sleeve band.
Take a pic of the install so we can see whats going on.
