‘71 three tube breather ?

[popslavaz]

I removed the AVS carb and replaced it with Holley. I would like to keep the three tube breather. The Holley has the rear port for the PVC hose,can I tee in the hose from the passenger side three tube breather???? Thanks

In one word, no. If you are running a aftermarket carb without an enclosed bowl vent valve, the 3/8” nipple on the breather cap needs to be capped off.
