Post fuel pump. I wouldn't modify the fuel pump at all other than removing the filter sock so fuel can freely flow through. Then I would put an inline fuel filter between the gas tank (fuel pump) and the fuel intake.
Replace Fuel Filter
Hey all,
I have an 05 Yamaha R6s with a filthy fuel filter. It was a pain to get to and clean and I wanted some thoughts on an idea I had: could I remove the fuel filter from the pump entirely and splice an in-line fuel filter into it? That's how my old 2001 R6 was and the maintenance on it was super easy! Thoughts?

Let me know how that setup works out for you!
What if you covered the fuel pump intake with a fine mesh screen? Not so fine that it would get clogged (that would ruin the whole point of doing this in the first place), but fine enough that it wouldn't let harmful debris through.No harm in having both. My only concern (as I'm sure you guessed) is the fuel pump itself is then subject to all the tank-crud. If you've looked them up, they're neither plentiful or cheap. Is there some other fuel resistant material that can be used to replace the sock? (that won't get sucked into the pump)
Here's what I ended up doing and it works great! I cut the in-tank fuel pump off (it wasn't working anyway) at the base of the tank using a Milwaukee oscillating tool. Then I ran a fuel line directly from the tank to an inline filter then to a high pressure inline fuel pump using barbed 90° elbows to make corners without kinking the line. Runs like a champ and total cost was $50. Also makes the maintenance way easier. I'll attach pictures.

The terminals would have to arc and spark at the same time as a fuel leak, and I don't have any wires near there that could touch both terminals. I'm not worried about it.
I think I'll take some sort of thin fire resistant cloth and place it between the fuel line and battery. Your concerns are valid, and I think that's a good solution. Thoughts?
Thank you! It's still working great! I'm sorry you had to dish out so much for yours. All in all I was under $100 for the fuel pump and filter. I can't remember if I mentioned it or not, but I did have to take an oscillating tool and cut the connection off between the fuel pump inside the tank and the output from the tank. That way the fuel pulled straight from the tank into my in-line filter and pump. Also, you'll have to cut the wiring connection from the original fuel pump and wire it to the new pump. Test that the wires are in the proper position and that the pump is flowing in the right direction before finalizing your installation. Best of luck to anyone reading this!Smart lad? My 05-R6 that i picked up for penny's, had sat for 16 years, where the inside of the fuel tank had turned into a ball of rust! & the seller think'n to sell, didnt look or think , & thought he could just throw in fuel & it would go? But this totally killed the entire fuel system, so after derusting & resto sealing the tank, cleaned the fuel lines & fuel rail, i then went looking for a new pump, filter, strainer, & injectors, i was slapped in the mug with a $1K price tag for a 05-R6 fuel filter? Where ya got'a buy the whole fuel module for that year production? & well you thought outside the box, & i was trying to think inside it, where my same set up as yours was trying to install onto the fuel module minus the old filter, but no matter how i tried? It was too tall to fit in the tank, & i just couldnt find a small enough filter that was no bigger than 40 microns? So i ended up falling in line, & handed over $1000 for a 05-R6 fuel module! I wish i saw ya post before i let the dealer parts counter dude bend me over! & as far as the nervous nelly's out there about your ingenious act? There are electrical insulation products out there to cover any & all exposed electrical connectors, to make it safer than factory. DUDE! Your Da Man!
If I remember correctly there are two separate plug-ins--one for the fuel pump and one for the fuel level sensor. Only cut the wires to the pump. The fuel level sensor shouldn't be affected as you're leaving the old fuel pump and sensor in place in the tank (while cutting a notch in the output of the old fuel pump so that the in-line pump can do its job). Does that make sense?Know'n ya slayed that Dragon! Which is a cool act! But i would like to know how ya got around the low fuel level sensor? As that little sucker is on the section of fuel module ya had cut away. & know'n the way ya pulled that fuel pump & filter set up rabbit out of ya hat, I'm sure ya pulled another bunny out, on this sensor deal? So i got'a hear & see all about this too? If ya got the time?
Ah man I wish I had documented the process better. If you live near the west coast I'll be happy to show you step by step in person but I don't have a video or another project bike to show you guys on. Sorry! Hopefully you can put the puzzle pieces together with the information I already provided. Best of luck!I'm planning on cleaning/replacing my fuel filter this season. Got any videos on how to do it? Never done this before, so detailed steps would be great
I bought a $30 high pressure (you have to make sure the pressure matches the bike's specs) in-line fuel pump and converted the oem pump to that one and it's still working great! I also added an in-line fuel pump. (See past posts for pictured) The beauty of it all is I have a way faster and way cheaper fix if my pump ever decides to go out again. $600 is outrageous for a fuel pump not to mention the labor to get it out and in!
I believe it's 50 psi but every bike will specify in the manual. As long as the fuel pump can pump out more than that then you're fine. Your fuel pressure regulator will keep it at the specified range. As far as issues go, I haven't had any yet. It's still balls cold here in Idaho, so I haven't been able to open it up on the freeway, but I started it the other day and it would jump to 16k rpms without any stuttering in the fuel.Been looking for some feedback/reviews on Quantum. I came across this last night. Needless to say, saves a lot more $ than the OEM. How is it working? Any issues with fuel supply & pressure with the aftermarket pump?
