For years all the DeLorean vendors have been using some aftermarket water pump hoses since the originals went unavailable. They were unique to the DeLorean and were easily identifiable, the left hand hose in particular, by the soft curve that arcs around the A/C compressor to the water pump.
Our supplier advised us that the aftermarket hoses they were selling us were being discontinued, so we decided to go ahead and have them reproduced (Made in the USA!) in the original shape, but regular rubber. Ed Uding/DMC Europe makes some silicone hoses in the same shape, but not everyone wants to pay that kind of money.
We sent off some samples, along with the drawings, and had molds made for the 108675 and 108676 hoses. These are now in stock!
