Does anyone know what sizes these fittings are?

Rear Drivers Valve Cover:
EVAP Solenoid:
Plenum right behind T/B left & right side:

5/16, 3/8????

Was going to do some braided hose to clean up the ugly plastic hose and fittings.

Where did you find these ? Anybody ever try them out ?

2011WhiteSS · 10-22-2015, 12:52 AM

Jegs or summit. But never tried anymore to get it to work.

It would be 3/8. Where do you plan to tap into for the driver side valve cover? I'm doing heads on mine right now and I was surprised to see the driver side capped off. Seems like you'd want a little vacuum in there to promote oil flow...

avido · 10-22-2015, 02:12 PM

i have this on my car. but on the evap solenoid are different but i can't figured out the size 3/8 is the right one for gas connection

Black Knight · 10-26-2015, 06:24 PM

So these would work with the driver and passenger valve covers.?

Bodywerks · 10-26-2015, 09:44 PM

Yes. But both heads share the same low pressure air. Not gaining much by paralleling the two valve cover vent tubes.

The one in the drivers side valve cover is restricted by a small orifice inside the fitting!

That looks like a Russell fitting. They still sell those, but have better design now. no plastic clip. dual o-ring prevents "wobble". threaded locking collar won't pop off. Also available as a complete hose end to reduce "stacking" of adapters and fittings.

I've tried all the sizes and had NO luck fitting the drivers valve cover for the L99 PCV port to my catch can.
But I've got some sheet metal valve covers and I'll weld whatever AN fittings I want. I gave up on the idea unless anyone comes up with a option that works.

There is such a thing as metric AN fittings. Perhaps it's a 10mm instead of 3/8. Evap is 5/16s or 8mm, same thing.

I used the newer style fittings when putting a TBSS intake on my LQ4. Connected them to the fuel rail and the Corvette fuel filter regulator.

Got around to do a few little things that I put off forever. I searched forever and never found AN quick connects to fit the PCV system nipples.
I cut up the OEM lines and used the ends. A little patience with a dremel and some epoxy and they look fine and work like I needed.
