Things were great and just in time.

I used this as part of a primer line installation on a 0-320 Lycoming. It worked well, the challenge was attaching the cone to the copper tubing, a machine shop had to braze it. The nozzle ports needed a 1/8 npt tap run down the cylinder to allow enough thread engagement for the nozzle. They did come well packaged. The copper tubing is challenging to flare since it is so small, re-doing a flare was needed to make a leak free connection.
