What other plastics are biodiesel resistant?
I've found some other fluoropolymers that are in roughly the same size. Mainly FEP and PFA (seem to have appropriate teflon-like chemical resistance and they're rated at high temperatures)
One is FEP with a 3.2mm ID and two different ODs, 4.8mm and 6.4mm. The max working pressures at 70F are 289 PSI and 450 PSI (which seems to be overkill). Anyone know the reasons for recommending the thicker wall tubing? 289 PSI is overkill, and the price difference between the two wall thicknesses is very large (for 25ft - $25 versus $73).

$1 a foot doesn't seem to be too bad of a deal...
