Unused plenum connections?

[caduceus]

I finally got the plenum back on the Chim last night, and after plugging in all available connections, I noticed two long nipples/pipe connectors under the hose that goes from the o/s rocker cover to the plenum. Fuel doesn't go there, nor water. The only thing could be vaccum or some other air function
There appears to be no more pipes to plug into them. So what are they for? And should I put some rubber caps over the end to blank them off?

Cheers
Cad

Are you on about the under butterfly area water heater ? over kill for our climate anyway to offset butterfly icing and thus sticking or reducing the airway metering in very cold & high humidity climates apparently some early TVR are plumbed in but never seen a serp Griff of Chimaera done so, if you blank off and remove that cover/housing remember those holes are open ended so need to be capped with shorter or cut-down screws 1/4 UNC I have previously ....

That's the puppies. Thanks Simon.
I'll blank them off with rubber grommets

No need they only go in and out its only the fastener holes that need blanking keep us posted on the run-up

Oh ok

Actually, one more question - The vacuum pipe that comes from the fuel pressure regulator. Where does it go? Under the stepper motor? I can feel a nipple type connection there, but can't really see it. And I don't want to take off the plenum again :/
