Safety wire is the only thing that will assure retention of the gascolator bowl.

Safetying them at that point is to save builders from them selves, in case they do not follow the PAP step by step (a lot of the posts here in the forum over the years indicates that a lot of people don't).
If someone chooses to wait until after leak check and flushing the fuel system, then the burden of responsibility is on them.
BTW, this is what we do in our shop, but we put a warning tag on the gascolator so that we don't accidentally bypass safetying them later.

Scott is there a reason why Vans didn't use the gascolator type that has a hinged retaining strap with a threaded knob to pull it tight to the bottom of the bowl? They seem easier to service.

Safety wire is positive locking, star washers are positive thinking.

Default Worldwide Shortage of Safety Wire in June 2017

Just finished the engine portion of my condition inspection, and tried to safety the 4 screws holding the gascolator in place. Spent nearly an hour trying to get it right, but it wasn't. Cut the wire and did it again, with success. There has GOT to be a better way to secure those fasteners, otherwise, I will likely use up all the safety wire in the world trying to do it again next year.

No where near as secure as the screw type and not acceptable for pressurized systems.

I hear ya. I wasted far too much time trying to get one run of wire around all four screws. Of course it was something like the fourth time I'd ever used safety wire. The guy who was helping suggested a different way, but I had already decided to do it my way. Should have done it his way, which was to use one piece of wire for the left screws and one for the right screws. Even backing up and starting from scratch would have worked better.

Ron,

I don't agree. My Cherokee uses the gascolator type with the wire bracket and screw. I have also used that type on several homebuilts with no issue. Seems like a better choice for maintenance.

Rich, do you think they changed the design over the years just to make maintenance more difficult?

Someone once suggested putting the safety wire through the back screws before tightening them the final last 1/4 turn. The gascolator does not depend on the tightness of the screws to prevent leaking. The seal is between the "O" ring and cylinder wall. All the screws do is to prevent the gascolator from coming apart.

I purchased stainless steel wire-lockable socket head cap screws (p/n90152A232) from McMaster-Carr. Using these made the re-installation a bit easier.
