RESTRICTION SWITCH ELIMINATED - FROM FUEL FILTER BASE-P/N

BULLETIN ILLUSTRATION LIST
SERVICE INFORMATION
Beginning with the start of production for all models listed above, the vehicles were built with a fuel filter base that no longer contains a restriction switch (vacuum sensor). It can be seen that the restriction switch labeled as number 13 in Fig 2 has been deleted from the present configuration as shown in Fig 1 . The model 80 fuel filter base has the same exterior form.
The Service Part number has not changed. Therefore, fuel filter bases ordered through GMSPO will not have a restriction switch. When installing a new fuel filter base on a 1989 or earlier model the restriction switch connector from the wiring harness will not be connected to the fuel filter base. The unused connector should be taped back to the wiring harness to prevent damage.
