Update,
Really simple process...
Take a picture of the top and bottom lines(for reference later)
The 4 top lines are all push tabs, and the yellow clip just slides backwards.
Have some rags surrounding the filter to catch the spilled diesel.
In the bottom, look at the picture you took, there is a grey tab on that wire harness, just push in and pull down, then grab a hold of that round plastic piece and pull down snuggly.. you can leave the rubber hose attached.
Then you will see a mount that is holding three fuel filter in place, has 3 tabs, but only 1 needs to be pushed, then just full straight up..
Once out, empty the fuel that's in the old filter and bring the old filter to your work bench next to your new filter, take a picture and note where the line Mark's are and just take of the bracket, it's a hex type bit.
Then unscrew the bottom sensor out of the old filter and install into new filter, once again, make sure mark lines up.
Top off new filter with fresh diesel,
Installation is the exact opposite, top is very easy, you may cus a little trying to get the bottom plastic back on.
Hope this helps...
