yes it does.

Drain fuel out of the filter housing remove the bottom, take filter out and wipe out with a lint free cloth, including the wif sensor. Put back together and take off wire connector, spray with wd-40 and reisntall.

open the banjo bolt on top of the fuel filter housing. Push the primer (its much easier with a wooden dowel). When fuel starts dribbling out of the open banjo close it. Start trucks.

the 89 has the sensor that screws into the bottom of the spin on filter... they're brittle and probably not cheap... havent had to price one; dont want to price one even tho in reality the sensor should be "water on wires" sensor... the insulation has pulled away from the body exposing 1/8 inch of wire... it gets wet enough... the WIF light comes on....
