fuel filter restriction

[Aristotle]

bob: that first link that you presented is the same filter that I use. It also does a decent job. However, would you happen to have an idea of how the 2 measure up to one another as the 2nd one seems to be a bit larger than the 1st one that is shown.

any noticable difference between the 2 by any chance??

I'm asking b/c I might wanna try the other out if I could ever get my hands on one and if it should prove to be better than the 1st one.

The only reason I went to the pleated paper element, as it has a larger surface filtering area .

Other than that, I can't tell the difference between the two, I don't know if I would use the paper element filter on a much larger displacement bike, as the fuel flow is quite a bit less, than the filter with the sintered metal filtering element .

I had to order mine from a motorcycle shop in I think Carson City, Nevada, only other place I saw them, was at Bike Bandit, not a common filter at all .

Wouldn't fuel flow through fuel filters having the same internal filtering material be controlled to a great degree by the i.d. of the filter's inlet and outlet openings -which are actually smaller than the fuel hose's i.d.? Bigger filter body not necessarily equating to better.

When I looked around for an in-line paper filter the common references pointed to NAPA SME 702323 and 3011 and the FRAM G4164 filters.  These are designed for a universal fit for 5/16 and 1/4” lines which makes them longer than I wanted.  As the NAPA SME702323 is a small engine/gravity flow type filter I went through other small engine references and came up with the Briggs  & Stratton 691035 (I've seen it referenced as a part number of 491629).  It’s a 60-micon filter with 1/4” single-barbed connection bosses.  Importantly for me,  with an 70mm/1.75” overall length (the NAPA etc are about 100mm/4”) it fits my length preference.

They are also available off the shelf in the lawn mower supplies section at Lowes and Home Depot.

I did do a flow check when I first got them.  I forget the details, but know they passed with flying colors.  In service, they work fine on both my R65 and my R100RT.  I think Monte uses them as well.

Yes. Yes I do.

Bob & Aristotle,

I agree with what you say and like the filters mentioned (cosmetically), but I did get the part reference from Robert Fleischer (http://bmwmotorcycletech.info/techindex.htm) thats why I was surprised when it wasnt flowing.  After a couple of removals and blowing the filter it now seems to work and was able to get the bike to idle for 10 min last friday.

Thanks for the help.  More questions to follow
