I have an Ebay knock-off BOV and a couple of other bits lying around so I thought I would try to come up with an alternative way to install one of the these on our cars. I've seen some utilize the existing hose and of course there are a couple of aftermarket OVCP's out there but I wanted one that would work without welding in a bung for the temperature sensor on my '86 Conquest. On EBay I then found this 2.5" flange adapter, a 2.5" to 1.75" reducer and a 2.5" to 1.75" 45 degree reducer that were long enough to reach the existing OVCP and I/C outlet. Then added a pair each of 2.5" and 2" T-bolt clamps and ended up with this. http://i663.photobucket.com/albums/uu353/carguygibby/IMG_20131020_161617_919_zps4fa33963.jpghttp://i663.photobucket.com/albums/uu353/carguygibby/IMG_20131020_163813_418_zpseb17c054.jpghttp://i663.photobucket.com/albums/uu353/carguygibby/IMG_20131020_163824_772_zpsdcd630f2.jpg Spliced in a T-piece for vacuum and I'm rolling around making PSSSST WHOOOSH noises with the best of them yo. It's a tight fit but works fine! Colin
