Looking like he’s changing a record in a 50-year-old console stereo, Ken Christely shows the fuel pump compartment to a visitor. The cad-plated fuel line running across the back of the backboard is an ’11-’12 Mustang GT part. Kenne Bell gets its test fuel system parts the hard way—purchasing them from a Ford dealer. Quick-disconnect fittings and numerous gauges speed testing. Not visible is the datalogging system on the backside of the backboard so Ken doesn’t have to write everything down.
