vent tubes into snorkel, good or bad

[lawdawg79]

Im curious if when building my snorkel and extending all the vent tubes if it is ok to pipe them into the snorkel itself. I cant think of any reason not to except maybe for the gas tank vent and possibly the valve cover vent. Would having the gas tank vent into the snorkel and essentially the intake be bad?

I will be making the snorkel from 4" exhaust tube if that makes any difference.

I wouldn't. You don't want any burps going into the engine.

All the fluids move and expand. You don't want vacuum pulled on everything.

Agreed. Primarily about the vaccum part.

Just run them all to one multi ported manifold, then run main line up as high as you can. The best tubing I have found to use is the plastic air brake line with brass fittings.

does it matter what size tube if I run them all into one??? appears that most vents are 1/2 inch I believe, so can I run them all into one final 1/2 inch, or should I jump up to 1 inch or something.

I think you'd be good with 1/2".

Its not like they are all venting full bore at once. Its just expansion, not flow.

Manifold them together, and run one breather up the back of the snorkel.

I think I ran 1/4" up to the manifold then 1/2" out and up. I don't think it matters......But the 1/4" fitting were cheaper and you need more of them.
