A good idea if it works. From memory the filter part is paper. Let us know how you get on.... :mrgreen:

The pressure regulator housing from the R bikes fits our regulator. With a bit of pipework and an inline filter you could get rid of it. Golan make the super mini filter which is all metal and cleanable.

 

I'm interested to know at what mileage people have changed their fuel filters. My Dakar has done about 38,000 miles and is on the original filter still. As long as the bike still starts and runs fine, what are the symptoms of the filter needing changing?

 

30k on mine and still on the original one. I'm guessing will be fuel starvation as the filter gets increasingly blocked with particles.

 

I good thought, if people tell us here how many miles they have done with their filter, at least we will know how long to give it. I suppose a lot depends on the fuel.
If someone could give the symptoms of a clogged filter or failing regulator, that would also help others out.

 

The Mule has almost 50k on the clock & still on the original.

 

I changed mine at 24k service as I was about do a European tour, I was also lucky enough to be offered a new unused one by a member of this site.

 

Here's what I did (re-used the pressure reg and put a washable inline filter on the bike) :

The last page is my solution,
alternatively to the R1100RT regulator housing different ones from BMW can be used, e.g. the one form the 1200Gs will work too.
Most interesting alternative could be the one they used on the BMW C1 scooter, as I *think* the 2nd outlet is already plugged from the facotry on this one.

 

125,000 miles and still on the original with no problems.

 

The F650gs regulator is rated to 3.5bar IIRC, and the pump delivers 50psi.
Google for "3.5 bar fuel pressure regulator" , "fuel pressure regulator housing" and you'll find lots.

The regulators are standard sizes available in various pressure ratings, housings match the size regardless of pressure rating. Make sure you get matching types. Better stil get a regulator or even a picture of one and visit a local scrapyard and ask/look far a housing that will fit it.

Google for a replaceable / washable fuel injection filter rated to at least 50psi.

Remove the OEM part and replace with the separate housing, filter and regulator. Put the filter in between the tank (pump) and housing.

Edit: I've done a bit more research....I quickly stopped off at the local scrap dealers. Most modern car engines have the regulator attached to the fuel rail - many seem to have the rail and regulator housing in one piece, so are not really suitable.
The owner quickly pointed me in the right direction. A common "boy racer" type upgrade is to repalce the regulator with a higher pressure one in an attempt to increase performance. There are generic regulator housings available from many performance upgrade shops that fit the bosch standard size fuel pressure regulator (available in many ratings, including 3.5bar ). Usually bling alloy things like this...

Shown with regulator....

Might not actually be that cheap if you buy the bling stuff, but should be easy to do. The benefit is you get a replaceable regulator ( which is commonly available anywhere in the world ), and a replaceable or cleanable fuel filter. Both advantages for the RTW type traveller.

That is why went and used the housing off of other BMW bikes, first of all it's cheap to get,
2nd you can fit a hose straight onto it with a hose clamp.
One problem with many of the cheaper universal housings is that they do have on fitting to attach right to a fuel rail (both the ones you linked do),
so these are not what where looking for here, unfortunately.

Of course a machined piece is much nicer :nod:

There is no reason not to use the regulator you have on your bike already, either.

 

Nice one Pete. That's a good bit of info. :thumb:

 

I've since managed to find a doc on the bosch website that shows dimemsions of the regulator and the housing.
Should be easy for someone like Komatias to turn one out on a lathe....

PDF for a 5 bar one , but dimensions are the same.

Hers a thought. Has anyone opened the filter up, and tried using the reg on its own somehow, and fitting an inline filter.
There must be loads of used ones out there, someone must have fiddled with one somewhere.

 

Read back a couple posts and check out the link I posted

I did just that, re-used the reg and installed an washable inline filter.
Pretty much exactly what Pete HK describes, too.

 

right, seen that link now, food for thought as I have an old filter in the shed I could take apart, thanks.
I like starting threads like this, gets people thinking

 

BTW Toby, what filter did you use? And how big is it ( dia x length )?
Thanks in advance! Pete.

 

I used the Sytec Small Bullet (10mm tails) filter, 34*77 mm as per item description,
the version with 8mm tails might work better for you, depending what fuel lines you end up using.

Not the smallest, but rather the best deal I could get for a decent washable filter (rated up to 6 bars/87 PSI) at the time I changed it.

 

What's a filter? I thought that's what we did in Traffic...
