Small Inline Fuel Filters

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I am not quite sure why anyone would need to be able to see the fuel flowing…..if it ain’t flowing the engine stops!The mesh size in the glass filter originally shown will be smaller than the mesh size of the filter in the tank so particles will get past the tank filter and collect in the glass filter.   I know that Rotax stipulate a 100 micron mesh size for their 912 series aircraft engines with Bing CVs so presumably that size of particle will not cause a problem - so no need for a 50 micron filter like the glass one.

	There are lots of reasons for the engine stopping..... My rationale for fitting this to a bike to which I've fitted a used tank which is over 30 years old is that despite my best efforts there may still be muck in it. It's easier to see if there's petrol flowing by just looking at the filter rather than undoing fuel pipes.....

	I guess you could disconnect the fuel line downstream of the filter and run fuel from the tank through the filter and into a can to see if any debris builds up in the filter? No need to have the engine running.

	True, but I would expect to see something in the filter itself. It comes apart for cleaning.

	Yes, I was just thinking that by doing that you would clean the tank with any debris going into the filter, and if it blocked you would not be out on the road.

	Could you guarantee getting all the muck out of the tank in one go? To be honest, if you have spent some time trying to get most of it out, what's left won't block a filter in a few hundred miles, so as long as you check that filter before each run, you won't get stranded.

	In my case, what's coming through so far is perfectly clear although that's just running the engine for a few minutes on the stand.

	Putting the tap onto reserve can help get any crud out.

	I've just been using reserve as I didn't want to put too much in.
