Anyone know?

looks like the tube thats supposed to go to a T fitting ans split and go to your fuel pressure regulator..

 

In the event that this is for the fuel pressure regulator, could this cause a P0441 EVAP Purge Valve CEL?

Thanks for your response.

 

that'd be a vacuum line. why is it shredded so bad?

 

Lol I have no idea why it's in that condition, I only recently purchased the car. It's pretty thin, not too thin to be a vacuum line?

 

Is there not a barb for that vacuum line to plug into your fpr that I circled in your picture here?

 

its pointing straight down toward the ground below the regulator

 

Crypto is right. The tube that's supposed to be there is there. Still trying to figure this out. Driving through a tropical storm today caused a SECONDARY AIR INJECTOR check engine light. Wonder if this can be correlated.
