    Odd question - To Cut or not Cut the "lip" around the filter gauge

    The filter system I have looks like it has a bad gauge. No prob, I went ahead and ordered a new glycerin filled gauge however, its a bit wider in diameter than the stock gauge its replacing and hence does not fit the filter housing as far as this "lip" around the gauge goes.

    I wanted to know if it was okay to just dremel off the excess and go. I dont' see any reason why not, its not something that appears to be anything other than cosmetic, but being new to all this I am just curious.

    As a side note, I woudl prefer to keep the gauge hence the dremel question as it was only $7 new.

    This seemed like a bad idea, but apparently people have done it successfully: Thread repair in plastic night be the right move.

    sorry what I meant was to dremel off the "umbrella" part of the filer cover. so that part that is kind of like a lip that is plastic its high enough that the new gauge with its wider body won't sit down.

    So in this picture:




    that black "lip" that is around the gauge that is part of the filter cover. that is what I am wondering if that can be dremeled down some. New gauge has same threads, etc.

    Go to the hardware store and buy a pipe coupling and a short nipple to raise the gauge. That way you don't risk ruining the gauge. Teflon tape to seal the threads too.
