Hey all..
Can someone tell me how to get to the External Fuel Filter change over post or e-mail me with the information if you have done this mod. Thank you.

All info related to that is here http://www.ibmwr.org/r-tech/oilheads/ex ... lter.shtml

done

i am doing the same mod. should be done with it today

I had no problem with making the modification but never could find small enough hose clamps for the two venting hoses that hang down past the discounects. Also did not use the metal pipe connector when you eliminate the internal filter inside the tank. I bought the emersible tank gas line at NAPA for a single piece precut at $20 a slice. You have to order it they do not keep it in stock. Only crazy Beemer fanatics are willing to spend $20 for a 6" piece of rubber tubing.

but you can use some 5/16 or 3/8 tubing in lieu of the $20 hose.

Are you using metal tubing? If it is rubber tubing it has to be a special in tank fuel line that will not break down when immersed in fuel.

the world has to know that i now also have external fuel filter so......

Pretty much followed everything in the first URL except 2 things. obviously i didn't use the adel clamp. I also ended up reusing the supply line and the quick disconnect instead of the new hose. so i got about 12" worth of hose left from the 6ft i bought.

total cost: $45 for 6ft of FI hose and bunch of FI hose clamps

rainbow tie wraps? a statement? No, not too obnoxious. But remember that simpler is better. If you are on the road and need to replace the filter, will you need that many tie wraps to secure it?

What is the big picture pathway of your fuel line? That sure will be easy to get to, but you're going to leak some gas when you do so have hose pinches with you. I have mine in the regular path of the fuel line under, almost, that black plastic shroud on the side...the one with the single torx25 screw with the black plastic extension that fits into the round rubber grommet on the frame. Just north of the QDs.

Oh, and in response #8 there is mention of the "small parts" QDs. Some people have had big time problems with those not fitting well. Not everybody, but yours truly fa sure.
The ones from Beemer Boneyard are the best

Right R10 is necessary inside the tank.

I see that R 9 was used for the externalization...that's good

i have a vfr and just realize honda's fuel filter looks like this:

should make the external fuel filter mod a bit easier if it can be used on the oilhead

it may or may not. Many people put their ext fuel filter straight in line in the normal hose pathway so the turns and curves offer no advantage.
In addition, one of the benefits of externalizing it is to use some other aftermarket filter; read "cheaper than BMW, but working as well, though may need replacement more often." At 47 euros, well that's kind of steep compared to a Fram.

Here's my conversion - I didn't think to reuse the curved hose inside the tank and
substitute a straight tube for the oem filter, so deleted the inside part from the writeup.

But I've found that the routing I did outside the tank has worked very well and is
out of the way and unobtrusive, yet very simple to quickly change filters.

I used a small filter and doing it this way was able to avoid using the big loop of efi
hose that was in the popular write-up of some time ago.
