I recently bought an '89 B2600iwhich I keep at my summer home in Rineyville, KY. It runs pretty good butdoesn't get great gas mileage, has quite a lot of underbody rust and I'm having some trouble with the front wheel hubs engaging on their own. I will check out the vacuum lines when I get back to KY. My truck is red and I love it. I never realized there were so many loyal Mazda pickup owners until recently when I started checking out Mazda related forums.
