In your opinion, is this still the common practice, or is Locktite 565 a better choice?
Are you using an engine that would be compatible with the Airflow Perf. pump (a fuel injected engine)?
If so, then the post I made earlier in this thread would apply (no gascolator would be used).
A lot of people have had success using fuel lube to seal pipe threads, but it is technically not a sealant and not what I would recommend.
There are specific recommendations in Section 5 of the construction manual. Loctite 565 (567 as well) is one of them and is a good choice.
A major benefit it has over fuel lube is the PTFE in the sealant. It helps prevent galling in situations where an aluminum fitting is threaded into an aluminum housing which is very beneficial if you ever have to remove/replace the fitting for some reason.
