What is the part number for the screen? I have a 4.2l engine?That screen is indeed a problem ----- it can cause the sender to not "see" pressure because the screen is plugged up.
But --- if that's so --- and there's something that is clogging up the screen --- you've got other problems anyway.
Besides ... this is about a 4.2L engine ... so what I just said doesn't apply to the 4.2L.
And PLEASE --- no more monoparagraphs.
See my answer?
Pose your statements in approximately the same format so people will actually WANT to help you --- we're all volunteers here and I for one, refuse to do this very much --- if I have to pick paragraphs apart to see what the trouble is ... OK?
