    I'll get back to it as soon as I finish my Beer and Bratwurst.

    :lurk

    Then my testing will look more like this.

    Ok here are a few:

    How did it install.
    How does it work.
    Do you notice any difference.
    Can you provide some pictures of the install.

    The installation is super easy. Plug and play for the electrical side of it. The one way valve to install inline is very easy as well. The only trick is the removal of the one way valve in the fuel pump itself. But if you go slow, in a few minutes it's out.
    Total install time, I would say 30 min taking your time if your pump is out of the tank. You don't even have to take the tank off, just drop the skidplate and loosen up the tank.

    How does it work and do I notice any difference? Well I took off the fuel pump out every few thousand miles to have a look at the filters. After my first 6000 miles, the sock filter looked like new (other than a slight color change to the nature of fuel). After another 4000, still the same. I surely am not worried about clogging the filters like I did after my first 4000 miles (on California gas). Every time you switch off the ignition, within seconds, the fuel pump reverses the flow for a few seconds.

    I have pix of the installation. I'll upload them to the server and post the links here. :freaky

    Awesome!
    Can you post pics of filters used for 10k miles or more with the purge unit?
    How often do you flush out the tanks from dirt?
    What mileage have you done with the purge unit installed?

    I can't find the pix of the filters.... I'll have to take pix again next time I pull the pump out.

    There is one more picture that I am trying to hunt down to post here. It is the picture of the removal of the built in valve that needs to be removed out of the fuel pump.

    I don't flush the tanks. There is no visible dirt. Of course it's there in the fuel but the point of the purge unit it to blow it back in the fuel so that it is not accumulate onto the filter's surface. A little "dirt" on a filter doesn't hurt. It's the accumulation of it that does and cripples the flow. Over time, it will surely show in the tank and I will flush them like I did when my fuel filters got clogged before I had the purge unit.

    I have over 15,000 miles with the purge unit. I pulled the fuel pump 5k miles ago (again) and they looks like they were when I installed them (other than the slight fuel tint that they got)

    hope that helps :freaky

    Thanks for being there for us mechanic n00bs....

    I used two cut up pieces of nylon wire tie. Fit right in there to release the top.

    I have been BAD. I do not know how long it's been. Easily 20k miles.
    It fell apart when I removed it, with little disentigrated pieces of plastic all over :eek1

    Yes, it still ran when I parked it :lol3
