Rick,

I am guessing that the difference between brake fluid and gas surface tension? is the issue, not the pressure involved. In this case, other than gravity, there is no head of pressure.

That said, at a HIGHER pressure fuel injection gas line would need to be more impermeable to GASOLINE, but I am guessing that brake fluid is a different animal. Could be the ticket, lets look into that!

I was thinking about something like "TYGON" clear plastic tubing, but it may be too stiff compared to rubber type line.

In another day or so I will button this thing up, and use what I have. Worst case it weeps...

Thanks again to all
