Hey everyone,
I’m looking for the correct valve cover to air cleaner vent tube that connects the air cleaner to the driver-side valve cover on a Olds 403. I’ve already picked up the rubber grommets that connect to the tube — now I just need the actual tube itself.
I found a couple listings on eBay for "air cleaner to valve cover breather vent tubes" that include dimensions like length and diameter, but none specifically state they fit a 403 Trans Am, just Oldsmobile's.
Here are the ones I found:
https://www.ebay.com/itm/167505629235 – "Short Tube": 5" end to end, 3/4" tube, bump-up is 13/16"
https://www.ebay.com/itm/197322151392 – "Long Tube": 6" end to end, 3/4" tube, bump-up is 13/16"
Before I order something that might not fit, I was hoping someone here could confirm the correct dimensions or point me to a source that sells one known to fit properly.
Any info would be appreciated — thanks!
