Is the fuel inlet from the primer injected upstream of the intake valve?

I just had to replace a line and it dawned on me I'm not certain of the answer to this question.

For some reason I had it stuck in my head that it went straight into the cylinder. But the more I thought about it the less sense it made. Heat and pressure would obviously be an issue.

I think I've answered my own question but I've never actually seen a diagram that showed the location of the inlet.

Yes
And is the same on all Lycoming engines

Goes upstream of the valve, but most cylinders have two different ports that can be used; One on the top and one on the side.
