The passenger side is a smaller hose and pulls from in front of the Throttle Body.
The Drivers is larger hose and pulls in after the TB.
The idea is the higher vacuum after the TB pulls air in from the passenger side and out the drivers side.
I have used heater hose with no issues since 2006 and have had no issues with it whatsoever.
But I would recommend Fuel line if available as it is better suited to the chemicals you may encounter. I have never had mine collapse and it works great to this day.
I sure get a lot out of the filter (Couple tablespoons at a time).
