When replacing all the fuel hoses is it necessary to use Nissan OEM fuel hoses with the protected sheaths on them. I see CZP sells 1 of the 3. But the other 2 from what I can tell are NLA. From older posts I read the sheaths are not necessary. I also read you can just slide the protected sheath off and one the new fuel hose. conceptzperformance.com/items/588/original/1.jpg or https://lh5.googleusercontent.com/_WgrSzzB6JAk/S_sula9Y3ZI/AAAAAAAAA3I/25l-XcbOG-w/s800/IMG_0186.JPG Does anyone know of a source for the 3 new hoses with the protected sheaths
