Guys installing the gascolator the directions say to safety wire the four screws on it. What I am wondering is exactly how to safety wire them? Not how to use the tool and wire but rather where do you run the wire? Maybe a dumb question and I searched the forums but no luck finding an answer.
The 4 screws that connect the bottom bowl from below have holes in their heads for the wire to pass through. Many online resources exist for the techniques. Basically run the wire from screw to screw in a way that it resists the screws unscrewing.
NOTE! You will have to drop the gascolator bowl after you do some fuel flow testing in the engine commissioning process. Thats to check for debris. So wait until after that to safety wire the gascolator or you will just have to cut the wire anyway. Hang some tape or something on it as a reminder.
As I built the plane I checked and initialed every step and signed each page when all steps were done. If for some reason I skipped a step on a page to do it later, I did not sign the page and I put a sticky note on it that stuck out visibly.
it can be a bit hard to get the wire through but I loosened the back screw a1/4 of a turn to get access to the hole and after threading the wire tightend the screw again pointy nosed pliers helped and I did as mentioned before don't try and do all four screws together just do the two left ones and the two right ones separately
Mine is not safety wired. Is there a big problem with these screws backing out?
It seems that the bowl is in pretty tight with the O ring. So when the screws are out, It still is a little struggle to get the bowl out.

I suspect the fuel pump may supply the required pressure to remove the bowl when the screws go missing in flight.
They say risk is made up of two parts: probability and consequences. Low probability of coming loose maybe, but very serious consequences. Mine are safeties.
Carl... I safety wired pairs of screws on the gascolator. From what I read, the safety wire is there to break if the screws start to back out. So if the wire is broken the screws need to be retightened. This info was counter-intuitive to me. I thought the wire was there to keep the screw from backing out. Silly me.
