Re: THIS is why you add an inline filter
01 Dec 2012 17:10 - 01 Dec 2012 17:15The last one I just removed was a little pancake filter like this:loudhvx wrote: Is it a paper filter for cars? Those always stop flowing for me after a few months. I think it's the alcohol in the gas partially dissolving the glue in the filter, then clogging the paper with it.
Prior to that I used a small scintered one like this, but it snapped in half.
Now I am just running a straight 1/4" line from the stock petcock, running on pri or res. I rebuilt and cleaned the petcock not too long ago. With the pancake filter it was running dry within a mile, actually stalling, and now without a filter (just the petcock screen) I was able to run two trips 30 mi each. However on each trip I had an episode where my lambda (installed on #2 header) was reading fuel starvation at part throttle.
So I'm not sure. Could be just the same symptom, fuel delivery issues. Seems like it is really marginal. Or it is just one or more of my carb slides sticking or something. Darned thing runs great other than the random bouts of part throttle fuel starvation, which is really frustrating.
I'll probably look at it again when I redo the fuse box. Maybe it's got an electrical gremlin.

Next time such symptoms occur, could run with the cap ajar, to determine whether adequate venting may resolve the issue.
Good Fortune!

I use that top filter in your picures. I have never had a single problem with it, so maybe the flow problem is something other than the filter in your case.
