The CorkSport Advantage

Performance Reliability

The CorkSport Braided Fuel Line was designed with the motoring enthusiast in mind with an easy installation and flexible design, and it replaces the OEM hard fuel line that is prone to cracking and leaving you stranded.

Quality Materials

All fittings are manufactured from 314L Stainless Steel for long lasting durability and strength.

The fuel line is manufactured from SAE100R14 Stainless Steel Braided Conductive PTFE with a Santoprene Jacket for excellent pressure, corrosion, and temperature thresholds.

Proven Design

Every hose is pressure tested to 3000psi in the assembly process and each batch has a sample pressure tested to burst failure. Burst failure occurs from 14kpsi to 16kpsi, this provides a Factor of Safety of 6.4 for an OEM fuel system pushed to its limits.

The fuel line is also rated for operation in temperatures up to 400F.

Flexible Fuel Compatibilities

Polytetrafluorethylene (PTFE) and Stainless Steels have excellent resistance to:

Gasoline

Ethanol

Methanol

Beer

WARNING!

If you are using an EGR Delete Plate in place of the OE EGR Valve you will need to source a bolt with the corrected length. The correct bolt length = EGR Plate Thickness + 9mm. Bolt Specs: M8x1.25. The bolt CANNOT extend past the housing it threads into in the cylinder head as this may cause damage to the fuel line. Failure to complete this will void the warranty.”

When building my engine for my 2010 speed3, I knew I would need to upgrade the OEM high pressure fuel line. Because the OEM line is known to be brittle and break down, I decided to be preemptive and upgrade it before any problems arose.

This CorkSport upgrade gives me the confidence I was looking for. It is usable with multiple types of fuel as well, which is a plus for me as I may decide to change my tune in the future. I have put a few thousand miles on so far with this line and haven’t had any issues! Highly recommend.

Good upgrade from stock

It is a good product, so far. Just wish it would mention in the description that you have to source out the O-rings if you dont want to reuse yours or cant reuse them. Kinda thought it came with new O-rings for the price but oh well.

Great product, definitely an upgrade from OEM. My fuel line broke and started leaking fuel as a lot of them do and i figured i would spend the extra $30 for a better product. Install was a little tricky but not impossible. Also, directions do not mention having to remove the intercooler but you will have to remove it to access the throttle body.

Every OEM fuel line i get keeps cracking. Does this come with the two M8x1.25x55mm Bolts in the middle of the line that holds it in place?
