I have a older Holley 670 street avenger and would like to use clear fuel bowl sight glass for making checking float level easy any recommended ones that will not fade out in color,break off or leaks?Thanks

You can buy the newer style bowls with the built in site glass in a kit from Summit etc., the old style clear screw in plugs for me were just easier to unscrew by hand rather than using the little brass screws but they always get "cloudy" over time.

My understanding was always that the clear plugs are for tuning and shouldn't be run. In other words, once you are done with float adjustments, replace them with the clear plugs.

I recently bought two pairs of Moroso brand sight plugs from Amazon. Use dielectric grease on the threads (per the instructions) and only tighten by hand.

Yes this is how they were sold. Put them in set fuel level and replace.
