Default Parts ID and questions.

Hello everyone, When I was taking my intake manifold off, some dry rotted hoses disintigrated. Now I'm PRETTY SURE that everything here is PVC related, I wanted to be sure. I would also like to know if these are things that can be vented to the atmosphere, or if they must be run back to their origional location in the intake manifold. Thank you.

VVV This is the hose that broke apart upon removal.


VVV This connector ran to the fuel line, is this the vacuum reference for the fuel regulator? There was a similar connector on the other side that went to the disintigrating hose.


VVV Here is the rear of the passenger's side valve cover, where the hose connected to it.


VVV Same thing except driver's side.


Thanks for all your help, i really hope this is somethign I can safely vent to atmosphere through one of those small filters, would make my life easier.

1A, 1B, and 1C is part of your PCV system.

1A connects to your intake, followed by 1B which is the PCV valve, and that connects to 1C which connects to the fittings on either side valve cover (3A and 4A).

Don't buy these parts from from the dealer, go to the parts store and get emissions/fuel line hose, a "T" coupler, little hose clamps, and a new PCV valve to make your own.

What's that do? I was planning on hooking up my fuel regulator's vacuum reference port to it.

it purges the excess pressure from the gas tank into the intake.
