    NAPA Fuel Filter

    I needed a fuel filter for my bike, the only one I can locate locally is from NAPA. It is an in-line 40 micron filter and seems to work well. Any feedback on using one of these vs. from a BMW shop is appreciated!

    Although I have not used on on my airhead yet....Napa filters have always served me well on various other machines, cars and motorcycles over the years.

    My feedback is that the screens on the petcocks are all you need.

    Then we should still have just oil screens and not have evolved into filters!

    Lots of difference between gasoline and motor oil, especially once the oil has been run in an engine a big. Your logic isn't.

    Could there be particles of crud in fuel that are small enough to flow through a petcock screen, yet are too big to flow through a carburater jet?

    are you sure you have petcock screens?

    I didn't. I ordered some and if I ever need to remove the petcocks I will install them. In the meantime I like the filters I got from Bing. The Napa ones are at least 100% better than none at all.

    "in an engine a big. Your logic isn't" Where's Google translator when I need it?!

    With regard to gasoline, do you know where and how it was stored before you bought it and are you 100% sure no dirt got in there? I've seen dirt in those see-through filters. So it must have been in my tank AND gotten past the petcock screen.

    I filled up with Sunoco in January and have not seen any dirt in the filter or carb bowls. I'm putting new filters in as part of replacing my fuel lines during my carb rebuild project.

    Yes! Use the fuel filters! For a buck or two every two years, well worth the money and frustration when the fuel bowl overflows because of a spec size piece of grit that got by the screens!

    I got mine from the BMW dealer (huge parts service) up in New Hampshire. Sorry, I am having a brain freeze and just can't remember the shop's name. They are very popular, reasonable, and very reliable and advertize in the BMW news.

    There's one aspect to inline fuel filters that seems to be rarely discussed. And, that's the effect of inline filters on fuel flow. I used to run inline filters until I did a flow test. My results indicated about a drop in flow (it's been a while and I think it was about a 1/3 drop in flow, but my memory could be wrong), but still sufficient not to result in fuel starvation. The filters were new and not blocked. It was my decision to remove the inline filters due to the drop in flow, since I didn't want to take the risk of additional loss of fuel flow. I haven't had any additional problems using only the screens on the petcocks.

    After 45 years of riding airheads I can't say that I have ever had a serious carb problem attributed to the lack of an additional fuel filter.
    The screens work well.
    If it gives you peace of mind, then go ahead and install the inline filters.
