|This bladder tubing is intended
for F2D models, where the bladder is relatively unsupported when
inflated. It will withstand repeated use in a large
compartment. The wall is 50% thicker than our YellowJacket tubing.
The new fuel line is a soft, black latex, 1.6mm(1/16 in.) inside diamter. All the current mechanical shutoff systems will pinch it off due to its low durometer(hardness).
