intake manifold vaccuum lines: all gone, now how do I plug?

[andrave]

I'm running vaccuum line for the fuel pressure regulator, one for the brake boost, one Y'd after the mbc for my wastegates, one Y'd for my blow off valves, and one for my boost controller.

1. Should I run them off the 4 into 1 tee under the lower intake manifold, or plug these lines and run them off the many vaccuum outlets on the upper intake manifold?

2. How do I plug/seal the remaining holes? I guess I could run vaccum lines to all of them and then put a bolt with a hose clamp over it, but is there an easier way to seal the lines at the manifold?

Thanks.

They have end caps that will plug right over the existing hole, nice and clean. Or you can snip a little peice of hose about an inch or so then take a screw which fits tightly in there to keep it sealed.

use a screw on each vac line. LOL

who is they? where do they keep these end caps? how do they install, will they hold boost, etc?

Dude, cmon, everyone knows "they". I think they're related to them. "They" have a website...lol. Just search google.

Seriously though, I fabbed a vacuum can and ran a larger line to it from the mani and tapped all the optional items off of it. I used various rubber plugs and caps from "They"....lol. Actually I got them from my work. But I plugged everything but the essentials that you listed already.

my brother said I can pick up the caps and plugs at advance auto or autozone.now for the other part of the question:which vaccuum source? can I block off the vaccuum ports in the intake runners? if so I could I could use the factory 4 into 1 vaccuum tee to run my vaccuum accessories off one of the upper intake ports.

haha, yes "they" meaning advanced or your local auto parts store, sorry. "They" also sell the clamps as well to throw on the end caps to hold boost.

ok. whats the best vaccuum source? I'd rather take them all off one source so that its easier to trouble shoot.

Best vaccuum sourceBrake booster lineYou should run that line aloneWhat did you did with the PCV systemActually I have only 3 ports opened in my KA stock manibrake booster PCV valve (stock form)Fuel pressure regulator

As for sealing the remaining ports, I like to use caps filled with silicone sealant and crimp at the bottom of the cap.

I'm just turning down the pcv valve...

I talked to someone and they agreed that the best goes to the brake booster. second best I'm going to tee to the wastegates.
