I have been using these filters for 20 years. They are easy to install easy to inspect for contamination and contain a metal (not cloth) screen

Due to previous experience with this style of filter, I really Didnt want to use it! After installation and preliminary testing, I am pleased. No leaks, correct barb size, unrestricted fuel flow. I only give 4 stars because Im waiting to see how it works after having fuel in it for a week. If it passes, then 5 stars.

I had 2 of these dump glitter particles into the fuel upon first use. One was original equipment on a brand new paramotor. The second was from Aircraft Spruce for a syphon to test fuel before putting it into the paramotor.
