I highly doubt that the plastic air brake tubing is formulated for continuous exposure to fuel and or vapor. Thes will cause it to crack and burst sooner or later. All plastic is not the same. You need the right materials, that are engineered for the specific application, to include temperature, vibration, exposure, pressure and operating fluid . Remember the Morton-Thiokol Viton o-rings on the space shuttle boosters?

Don't try to re-invent the wheel, or second-guess the engineers, the results could be catastrophic.
