    Gas Filter and Water Separator Change

    There are a few good threads and YouTube videos on this subject, but I thought I would throw out my experience in the process, and maybe some hacks, and stumbles. Changing the fuel filter in the canister wasn’t as daunting as I 1st initially thought it would be. After staring at those stuck on hoses and wiring for a few minutes, all in a tight spot, and wiping the sweat off my brow, I thought, I wonder if this is doable without removing anything other than the low pressure wiring harness..?

    7/16 deep well socket, 5/16" nut driver, 7/8" box wrench, picks for o-rings, rags, drain pan, bright light(s)

    Disconnect harness, it's the one you can see and access. Push in on the locking tab and pull apart.

    After wrestling with one of the gas lines, there was no way that thing was going to budge without some slicing & dicing, and for some reason I was a little uncomfortable putting a heat gun next to anything related to fuel. Hose is going to stay where it is.

    I keep a stack of aluminum pans of various sizes in the shop. Moldable and come in handy.

    ​Concept was good, but there was no way I was getting than pan full of gas out of there intact. There a a few kitchen items that come in handy. Word to the wise, get your own, don't raid the kitchen. Just sayin' from experience here. Turkey baster was the only thing I could think of at the time as my go to fuel transfer tool.

    Multiple turns with a 7/16' will get it loose enough to undo the clasp on the back end.

    A few gentle wiggles while working the canister down will slide it off the 2 o-rings at the top of the canister housing.
    I was able to set it between the rail and engine with out removing any additional lines or hoses.

    Picked the filter out. Some needle nose pliers might of come in handy, but I was up for a challenge (more like not crawling in & out of the boat while solo), and was able to work the old filter out with my fingers

    O-ring R&R. Out with the old, in with the new. I used a light touch of silicon on the o-rings to assist in the bowl sliding back on.

    I placed the new filter in the bowl, slide up and over, a little wiggle and upward pressure, you'll be able to visually see the cup is as far as it will go.

    Reverse the process, clamp back on, and plug in harness.
    I did 3 complete start and stop cycles at the key pad, and then did a 30 second start up to check for leaks, fired right up.

    I thought I would get the hardest out of the way 1st, before moving on to the the easy fuel separator filter.
    I mean, how hard could that possibly be? A filter wrench and a couple of spins.
    Man was I wrong, I got worked.
    Details to follow...

    WATER SEPARATOR CHANGE:

    This was a mother bear!
    Breaker bar with an extension tube, Son on one side, me on the other, it would not budge.

    I have never had a filter beat me with this set up. It might destroy the filter, but it will come off, except for this time.

    Had to remove the whole unit.
    The gas hoses are as one with the barbs. I didn't snap a picture, but you can cut a v-groove with a razor knife about 3/4" long on opposite sides of the hose.
    This will speed up the hose removal process, and fortunately you should have enough hose that you can spare an inch or 2 from each side. The filter housing unit removal is self explanatory with 2 screws and lock nuts. Have rags or absorbent materials in place, you'll spill a little gas.

    Housing snuggly locked in vise. Busted out the death grip of oil filter wrenches and she budged, finally.
    I might mention, probably shouldn't have to, but you'll want to drain the gas out through the barb before jumping to this step.

    Supposably this filter was changed by the dealer 2 Seasons ago, or at least I was charged for it.
    Not wanting to assume, but I've got to question that.

    I think going forward, this one is getting changed every season.
    I used a touch of silicon spray lube on the gasket, and a light touch of anti-seize on the threads.
    It will be interesting to see how this comes off the next time.
    Start & stop cycle 3 times on the keypad, 30 second start to check for leaks.

        Great write up! I did mine in the fall. The motor in my 200V sits tight between the dividers and the angle braces are right next to the separator filter. I too thought the it would be the easy one and did the other first as well. My filter did come off but not without a fight and I did tear mine up with filter wrench.

        Looking at yours, I too would find it had to believe it got changed.

          That was a nice write up I used a funnel with a hose connected to the end of it run it through the bilge plug and into an empty bucket under the boat and then open drain plug.
          tried something different this year. My boat has the screw in type filter so I wanted to try forgoing the funnel with hose. I unscrewed the filter and carefully lowered it the fuel was about 3/8 inch from rim. I went and got the turkey Baster from the kitchen removed some fuel from the canister and lifted canister from boat. This was faster than dealing with drain plug. Wish Scooter would have wrote this up around Thanksgiving when I did this it would have saved me some grief should have bought my own baster
