external fuel filter modification

I read a thread on external fuel filter modification for 06 and older stroms. I have an 08 and was wondering if anyone has come up with a satisfactory solution yet?

External fuel filter

I'm not convinced an external filter is necessary, for the simple reason that it only filters fuel after it's already been through the pump. I just replaced the entire fuel pump assembly on my 07 because the tank was quite rusty. The fuel going to the injectors was clean, but the screen filter on the pump was so full of rust it disentegrated as I was disassembling the pump. I decided to replace the entire assembly as a preventative measure rather than just get a new screen/pre-filter. Hopefully regular inspection and replacement of the screen will prevent any more problems with the system.

I haven't read about anybody trying an external filter mode. The older filter 15410-24FB0 lists for $282 and the one for the newer pump 15610-27G00 for $108 so the incentive is not as great.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.

There is a post by Skillo, who is now anonymous on VSRI, but this was for a 1000 and meant drilling into the HP fuel filter area and bypassing the one inside the tank. This mod is only available for the earlier models, you can read about that in this thread

http://www.vstrom.info/Smf/index.php/topic,6105.0.html


If you can work out a way of bypassing the internal fuel filter, please let me know as I was a victem of crap fuel thoughout South America.

I'm going to have to look into this to see how feasible it is. I did it to my BMW R1150GS fairly easily (fishing the filter/pump assembly out of the tank was the hardest part) so I can't imagine why it would be more diifficult with the Wee.....but.....

The high pressure filter on the later pump is tiny. It is contained in the regulator #7. The inlet screen #2 is almost two dimensional. Good luck.

Just curious why you had to replace fuel pump and or filter already on a K7? I am just wondering as I have a K7 too, I ride it almost everyday and have 32K miles on it no problems yet. I don't see no rust visually in the top of my tank but to be quite honest I don't know what it looks like down in the bottom as I have never had it apart.

Any clues as to why you tank on such a young bike is rusting? Can you give an idea of how your storage procedures go? Does the bike sit for longer periods with a less-that-full tank of gas?

It's on my "to do list" . The problem is you never know when you may get bad fuel.The fine filter just dose not have enough area for more than a few bad tanks of fuel, a car filter on the other hand has hundreds of times the surface area and you can replace them for under $20. Outback Australia is no place to get a bloked filter amd i think they do not sell just the filter ,even if they did the pump will have probably been damaged enough that you wil have to replace it .Last time I heard it was $1200 in Australia for the pump assembly .

My tank and pump looked fine, it was just the low pressure screen that was clogged, but it would be nice to have an external mod.
