Premium Member 2and3cylinders Posted March 4, 2020 Premium Member Share Posted March 4, 2020 Typo, if crap loads up the screen/filter, we're SOL? Link to comment Share on other sites More sharing options...

But it would take a REALLY contaminated fuel source to phuck up and clog the filter. I really wouldn't stress about it. If you're in doubt, check your fuel pressure, a clogged filter can cause a low reading on the fuel pressure tester gauge. -S 1 Link to comment Share on other sites More sharing options...

Mvich Posted March 24, 2020 Share Posted March 24, 2020 This fuel inlet screen can be found on any engine with a pump in the tank and clearly can only stop large objects but one could install a real inline filter to protect the injectors. Worth a try. Link to comment Share on other sites More sharing options...

Worth a try. I don't think that's true. My two previous fuel injected bikes (BMW K100RS and Triumph TT600) didn't have a screen, there was just a pickup tube drawing fuel through an in-tank canister filter before the pump. Hence I expected to find a similar filter in the FJ-09. Link to comment Share on other sites More sharing options...
Mvich Posted March 24, 2020 Share Posted March 24, 2020 I based my comment on my outboard motor. It has two inline filters, one for debris and one for H2O. I haven't seen the FJ-09 fuel schematic beyond what was posted on this thread & I don't want to be confused with someone who knows what they are talking about Link to comment Share on other sites More sharing options...
vijay Posted March 25, 2020 Share Posted March 25, 2020 You could always jury rig a small filter to put in the tank filler hole each time you pump gas if you are concerned about particulates in the gas/petrol. Link to comment Share on other sites More sharing options...
3banger Posted April 4, 2020 Share Posted April 4, 2020 (edited) So the FZ-07 Filter is almost certainly a Denso fuel pump assembly most of which have an integrated non serviceable fuel filter. Actually I’m pretty sure most Japanese and Eruo bikes have some variant of a Denso fuel pump/filter system. My old Triumph 1050 had a similar system and I managed to develop a work around.

When I had my FJ-09 tank apart I noticed that the fuel pump had a Mitsubishi logo on it, so not Denso. It looks like the same basic concept though. I'm confused by your photos. Is your added fuel filter before or after the pump? Link to comment Share on other sites More sharing options...
3banger Posted April 14, 2020 Share Posted April 14, 2020 My added filter is after the pump and external to the tank. The OEM design also has the main filter after the pump its just part of the white plastic assembly. The only thing before the pump inlet is the pickup screen. The filter is to protect the injectors. 1 Link to comment Share on other sites More sharing options...

3banger Posted April 15, 2020 Share Posted April 15, 2020 Does my link to my google doc work? It might only work for others with google drives? Anyway, it is PDF describing step by step what I did and why. I couldn’t load a pdf doc to this forum. Link to comment Share on other sites More sharing options...
Premium Member 2and3cylinders Posted April 15, 2020 Premium Member Share Posted April 15, 2020 Because I am oldish, I didn't realize there was a link... You are more insane than I am! Now I understand you did this mod on a Triumph and not the FJ-09 as much as an exercise to see if you could do it as to save money down the road (pun intended). To challenge yourself. Personally, the time spent and chance of creating a Roman Candle you straddle between your legs would not make this project worthwhile to me even though a new pump and O-ring is $271 + shipping. Very nice effort though but doing something similar to our FJ -09 would entail a entirely new and more extensive R&D effort, as our fuel pump appears to have a fuel level sender built into it... 2015 Yamaha FJ09 (FJ09FR) Fuel Tank | Part Shark Shop online for OEM Fuel Tank parts that fit your 2015 Yamaha FJ09...
