PCV Hose 351C
#11
Hmmm.... I have the same but the 735. I don’t really remember mine saying that, but like it says, it doesn’t matter as long as they are separate. Now I remember why I didn’t use the front port for the pcv, it’s on quite an angle and was worried that a hose would collapse from the sharp angle. So what I mean is it doesn’t come straight out from the front of the carb base, it’s angled toward the passenger side of the engine. I couldn’t come up with anything at the time so I just connected directly to the manifold. Not right but like I said it worked.

Ok I just checked my instructions for my carb and it says the same. The back can be use for either just not together.

Just because it's a Holley doesn't mean they are all the same.
Here is a 4160 PN O-8007.

And here is a 4160 PN O-80457 or O-1850

That's why I shaped the steel tube the way it is. It works well.

Quite right Don, they're ALL different it seems, no consistency between models, Very confusing. I guess the best and only true way is read the instructions for the model bought.
