Time for a new filter?
« on: July 11, 2014, 11:58:10 AM »
My engine run had been getting more and more troublesome of late.  So, after being reminded by my flying buddy I looked in the obvious spot.

This is after things have dried out -- there were some puffy white boogers in there.  I was kind of surprised that nothing was moving on its own.

Think it'll fly better with the new filter?

The problem with electric is that once you get the smoke generator and sound system installed, the plane is too heavy.

Do you filter between your fuel can and the tank?

Yes I do!  I use two filters in the fuel can.  I don't know if there's just a lot of fluff in the air right now, or what, but part of what got me looking at filters on airplanes was the fact that my lower fuel can filter was totally clogged.

Tim,

If you are using muffler pressure - a filter in the pressure line to the tank catches lots of crud. Amazing how much dust and dirt gets deposited in a muffler, and pushed through the pressure line into the tank!

Tim, if you're using a syringe, as I suspect, you pull fuel into the syringe through an attached filter and then push it into the tank through the same filter? If you're doing that, you're "back-flushing" the filter contents right into the tank. How do you protect your fuel syringe between flights and flying sessions? There are many ways for a syringe to put corruption into your fuel tank, even if the syringe piston seal doesn't contribute to the problem.  n1 Steve

No, I don't us a filter to carry crud from one place to another!  There are two filters that stay attached to the can.  I suck up fuel with the syringe, disconnect from the can, attach to the tank, and squirt it in.

I may be picking up stuff, but the filter shown is over a year old.

    Hi:

     Try back flushing with a carb or brake cleaner.  Use the straw that comes with the cleaner and a pice of fuel line for a connector, CAUTION Wear eye protection whhdn doing this!

     The white "crumbs" may be from rancid castor oil.

                                                                                                                               Good luck,
