Move the fuel filter?

[Longrider]

Is there any reason to keep the fuel filter in the tank? Up to all that again ..... plugs and fuel filter and I'm sick of pulling all that stuff out of the tank. Does anyone know of any reason that I just can't put a bit of fuel hose in the tank to bypass where the filter is and hang any (not plastic) filter "in line" outside the tank?
Someone has to have done it!

Well, maybe, but it could be a packaging issue, and that may be why it's in the tank anyway....that's where there's room. It would have to be rated for fuel injection pressures of course. That runs rather high.

Haven't seen or heard of it being done but it would be easy enough to rig something inline in the rubber section of the main line that runs under the front of the seat. Especially if you have removed the underseat filter and plenum ducting.

It would have to be rated for fuel injection pressures of course. That runs rather high.

about 3 bar is what she runs at. you would also need to ensure the filter will flow enough too while maintaining that pressure, assuming you're not using the OEM / Mahle KL 145 or exact equivalent.

relocating the filter from before the fuel pressure reg in the tank to outside the tank (after the pressure reg) may have an adverse impact on pressure.
i.e. if the OEM dropped pressure by say 0.5bar then supply pressure to the injectors would be 2.5 bar instead of 3 - assuming you only move the filter only to outside the tank - moving the reg also would require fabrication of a return line to the tank.
i can't say what pressure drop (if any) the OEM filter has, as all the tests i've done were with filter between pump & reg. chances are it is negligible on a stock Rocket anyway.

biggest problem i'd see with the relocation is spilling fuel from the line when you go to change filter. you would also lose a large % of fuel filtration in the tank since the reg recircs double filtered fuel within the tank

Do you Aussies never change your fuel filter when you have the tank off for your six times a year deep clean

No that would get in the way of riding time

What?? It looks plenty clean in there. Why should I go poke a skunk?

No No you do not clean inside the tank you clean all the micro particles of dirt that accumulate under and around the tank, use lemon pledge best stuff on the market

OOOOOkay I just installed a set of 440 on my R3. Saw what you mean. Crannies with backed dirt and grime.

I don't know what is causing Longrider to be "sick of pulling all that stuff out of the tank". in 9 years and 40,000 miles I've changed the FF once. It didn't need it, but I thought I just should do it. What is happening Longrider to make you have to change your filter so much ?
