Fit a large area gauze filter just under the tank filler . With the tank cleaned out when new very little contamination can now get in and any line filter in injector pipework will have little to do and rarely need cleaning .
Make the tank filler filter very simple – drop in and make easy to pull out . A basket shape is best .
As regards the line filter for the injector have a good big free flow area to avoid bubble clogging .
