I need to replace the hoses to/from the oil/vapor separator on my '91 Spider. Based on threads here, they are NLA. Have not been able to find any from the usual vendors. Hiperformancestore.com sells replacement hoses for up to '89 models, but Greg there does not know if they will fit Motronic Spiders. So, does anyone know if these are available from anyone, and if not, does anyone know if those Greg sells for an up to '89 model will work on my Motonic? I do not have access to Alfa part numbes, so cannot tell if these changed with the changeover to Motronic. Any help appreciated!
