Our 69 Yenko Chevelle restoration

These tubes travel right up to where the structure metal goes horizontal and that would provide some protection from debris. I’d also say this isn’t in a high splash area either and there wouldn’t be much of a water/contamination issue. For that matter, the plastic vent only had foam in it too, at the junction port, and would have been just as susceptible to contaminants. JMHO.
