NOTE:
The previous bulletin acknowledged using TPCV, P/N 17091152, which is used on Eldorados and Sevilles. It can be used on DeVilles and Fleetwoods,
however, the TPCV control vacuum cover tube must be rotated 180" to align in the same direction as the canister tube. Refer to Figure 1. If the TPCV is
not installed correctly, then the vehicle may experience a condition of high tank pressure. Therefore, to avoid having to rotate the TPCV for DeVilles
and Fleetwoods another TPCV has been made available that is already in the proper alignment.
