Hey Bryan – thanks for the message!

We get asked about that a lot. We advise against the vacuum line method (don’t induce Sea Foam through the vacuum line).

Instead, use Sea Foam Spray applied through the air intake. This works better for two reasons: one, it disburses evenly to all cylinders so it cleans better, and two, it’s much safer since there’s no risk of hydrolocking an engine. Hope that makes sense! Give a try next time you’re due for a cleaning.

Thanks for using Sea Foam!!
