I dont think it would cope with the heat on the engine bay alvis It needs to be like vacuum tubing , have you used that in your bay ?

I just rang southside motor factors on the kylemore rd they have a few different sizes iv to bring a lenght out and match it up

Have never seen it out there before not quite sure were it is has anyone been there is it beside anything big that shows up on the map as I cant find it on google maps
