    OK, I received some great tips on how to clean up my TBI throttle body now just one more question. How do I depressurize the fuel injection system on my 89' so I can replace the fuel filter (I know the filter rides inside the frame rail). Thanks for any info

    I just had a cup ready to catch the fuel as it comes out of the line. It was no worse that changing a filter on a non FI rig. Let the rig set for a few hours or overnight it should let most of the preasure off just sitting.

    Be sure to keep some rags handy and wear safety glasses!

    The system depressurizes after a little while so no big deal, but it does make a mess and loose quite a bit of fuel, I've learned this the hard way.

    no big deal,let the truck sit for a few hours and then crack the line loose...you will get gas coming out so cover eyes and maybe put a drain bucket on the ground.

    Or take the ecm fuse out and crank a couple of times. This will let out the pressure also.
