Hey guys.I have a new old stock GM NB9 fuel filter system only used in 1985 5.7/4.3 diesels before GM pulled the plug on these forever.Has the water in fuel sensor,etc.The fuel filter is also in place.

These are very rare and hard to find since they were only offered in the last year of production.The NB9 replaced the previous 1978-1984 model 50 rectangular filter held upon the filter bracket with a wing nut.I’ll upload some pictures shortly.Asking $300 plus freight to your location.Thanks
