GUIDE
Polyester vs Polyether TPU Fuel Bladder: Diesel, Gasoline and Jet Fuel
The single most important fact about TPU fuel bladders is the polyester/polyether distinction. Polyester TPU is the industry standard for diesel storage. It is not suitable for gasoline. Gasoline and jet fuel need a polyether TPU configuration.
COMPATIBILITY AT A GLANCE

Ordering the wrong grade is not a small mistake — it is the wrong product. The table below states which fuel each bladder material stores.

WHY THE DISTINCTION MATTERS
Why polyester and polyether are not interchangeable
Fuushan states: 'Polyester TPU is used for diesel and is not suitable for gasoline. Gasoline requires a polyether TPU configuration.' The Jinlong TPU page says polyether fits gasoline, jet fuel, diesel and water, while polyester fits only diesel and water.

BEFORE YOU ORDER
What to ask before ordering
Tell us the exact fuel and grade first. For gasoline or jet fuel, ask for the polyether grade — availability and price are quoted separately. Confirm the fittings, valve, vent and flame-trap and the antistatic and grounding specification with the order, never assume them.
