Fuel Tank Crossover Tube: Installation

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: Note the location of the T-shaped alignment feature between the jet pump feed/return pipes connector. Note the T-shaped alignment feature on the crossover tube. The crossover tube will not fully seat into the fuel tank if the jet pump lines are misaligned.
  1. Lubricate the right crossover tube to fuel tank connection "O" rings with Rubber Lubricant (1051717). See Fig 1. Lubricate the crossover tube "O" ring mating surfaces with Rubber Lubricant (1051717). See Fig 2. Connect the crossover tube to the right fuel tank.
  2. The crossover tube collar tangs will not latch if misalignment exists. Rotate the crossover tube collar clockwise to engage the tangs. Rotate the crossover tube CPA retainer counter-clockwise past the collar latching tang and push the tab into the locked position. If the CPA retainer is locked into position, the crossover tube collar will not rotate.
  3. Test the crossover tube to fuel tank connection by attempting to rotate the crossover tube collar counter-clockwise. Repeat procedures for the left side fuel tank. Snap the crossover tube into the clamp located above the transmission. Install the driveline support assembly. See appropriate DIFFERENTIAL & DRIVELINE article in DRIVELINE/AXLES.
