Recall of GM Pickups Urged: More than 2 million General Motors pickup trucks are vulnerable to fires or explosions because their fuel tanks are mounted outside the frame rails, a consumer group said in urging a recall. The Washington-based Center for Auto Safety asked the National Highway Traffic Safety Administration to investigate the alleged defect in 1973-1987 model Chevy and GMC full-size trucks with “side-saddle” tanks. Newer models have a single tank within the trucks’ frame rails. The group estimates 2 million to 4 million trucks are involved.
