• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage.

2017 F3-S Fuel Filter Replacement & Re-Location

Hi Everyone,

Part 1.

OK, it was time I looked at replacing the Fuel Filter on my 2017 Spyder F3-S. Prior reading alerted me to the fact it's not an easy item to replace because of where it's tucked-in just below the handlebar riser on the RHS of the Spyder... you have to remove all the plastic panels (except for the Frunk) as well as the seats, mirrors and the Instrument Cluster Panel to uncover the filter. Even the panels on the LHS of the Spyder have to come off so you have access to (2) screws at the top of the Fuel Tank cover.

Now, the rearmost ends of the Upper Panels are clipped to the Fuel Tank Cover using hidden clips. These are only plastic clips so treat them with extreme care or else you'll break them. Watch this short video on YouTube for help on releasing those clips:


It was at this point I decided there was no way I was going to fit a maintenance item back into the same impossible location, so I started looking to where else I could fit it, so I made a bracket from 25x3 Aluminium flat and mounted the Filter alongside and just below the Brake Fluid Reservoir. I had to get creative with the new Fuel Hoses (the return hose needed replacing anyway, coz the end had started to stress-crack), and rather than write a wordy explanation, I'll let these marked-up pictures tell the story, with Part 2 in the next post:

Things to note are:

- All Fuel Hoses are Ø 5/16" EXCEPT the Return Hose, which is Ø 1/4". You need to use Ø1/4" for this 'coz the return port barb on the plastic Y fitting is Ø 1/4".
- The Return Quick-Connect fitting on the Fuel Pump has a Ø 5/16" barb, so it'll take some pushing to get it into the Ø 1/4" hose.
- In its original position, the Fuel Filter is held in a clamp that bolts to the Chassis. Also clamped by this bolt are earthing wires. Remove the Clamp 'coz you'll use it to hold the Filter in it's new location, but don't forget to fit the bolt and the earthing wires back into it's threaded hole.
- Existing Fuel Hoses are clamped to fittings with single-sided Oetiker Clamps. Don't try to cut these off, you're just wasting your time. Instead, pick them apart as shown from 7:28 here:


Naturally, check for leaks by running the engine for a couple of minutes before putting everything back together.

Hope this helps someone. :)
 
Well I'm just in the middle of replacing the spark plugs of my F3-S and while I'm there I'll do the fuel filter also...

Big thank you to you, this thread has been of great help.

Happy New Year.

Glad it helped :)

Happy New Year to you too.
