I have an '04 Cobra with 14k miles on it. While putting it in storage I realized that the boost gauge stopped working. How exactly could this be fixed?
Check the lower boost barb behind the blower... Bet the rubber coupler popped off... If not check the hose that goes into the fire wall in the passenger side of the engine bay... Even further the connection behind the glove box or the connection behind the gauge cluster
I'd check the line first which runs alongside the steering column and then cuts over to the passenger side, held on with plastic black tabs on the dash frame. It then goes over the heater core and pops out through the firewall. It disconnects behind the glovebox door.
