Is that connection not tight enough?

The fuel rails have been off several times. I don't think they are the issue.

Can you get a vid of the gas dripping out of the FPR vac port nipple?

Cool.

But exactly what was going on there? Where was the fuel coming from?

Knowing what might happen with others is good yUp!

The FPR is failing internally, allowing fuel to move from the supply side back into the plenum through the FPR's vacuum line.
