Trivia... in Canada, it is so cold... your hand cramps up and O's become U's.
Just can't get over the top. Even their loops in RV's are ovals...

Oh, one other thing I did was use K&N filter grease to create a better seal between the filter and the airbox to keep any water out

Humm, I've never seen a FI plane without a gascolator. It's imperative you keep any contaminants out of the injection system.

My understanding (which might be incorrect) is that the gascolator is not effective at trapping water in an FI engine because the higher fuel pressures will just push it through. There are other filters for contaminants in the system. I have had several very knowledgable people, including Don at Airflow Performance, tell me that I should remove it.

Recommended to remove the gascolator...but you still need a fuel filter (or two), usually located before the fuel line penetrates the firewall. This is done to minimize heat absorption.

The gascolator is the pre-filter, water separator and particle trap before the finger screen in the servo. If you sump the gascolator prior to start up any water and contaminants will be removed ( in theory). There is no pressure in a gascolator, just flow. I'm an A&P and I've never seen any FI engine not have a gascolator. They are in every plane we build. I can't see any reason not to have one. But they certainly aren't required in a home built. I've never seen one fail and I would much rather clean a gascolator then the servo screen and injectors.

The fuel tank drains are the lowest part of the system for collecting water prior to startup. The reason not to have a gascolator is that it transfers heat to the fuel. There is another filter prior to firewall penetration, it just doesn't have a drain for collecting water.

Default gascolator

Never saw a gascolator on McDonnell Douglas, Boeing or airbus.

Haha.. If that's what you're flying then you're in the wrong forum..
They are gascolators....Not JetAcolators...
