Fuel Tank Crossover Tube: Removal

WARNING: This page is about a different car, the 2003 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: The crossover tube Connection Position Assurance (CPA) is released when the latch disengages from the tank connection groove.
  1. Remove the driveline support assembly. See appropriate DIFFERENTIAL & DRIVELINE article in DRIVELINE/AXLES. Remove the crossover tube from the clamp located above the transmission. Disengage the left crossover tube CPA retainer by pulling the tab outward and rotate. See Fig 1.
  2. Rotate crossover tube collar counter-clockwise to disengage. Disconnect the crossover tube from the left fuel tank by pulling the tube straight out of the fuel tank connection. Repeat procedure for the right side tank.
