Fuel Line

Why should I use Fast Flow Fuel Line?

Our fuel line is a proven product that has been in use since 1969. It is still manufactured in the United States.

What is the material?

Our fuel line is made from a poly blend with additives to resist fuel, solvents, race gas, and oil. It is a real fuel line, not surgical tubing marketed as fuel line.

Can I use this fuel line for fuel-injected applications? What is the maximum allowed PSI?

This is a low-pressure fuel line. It is not intended for fuel-injected applications. We recommend 15 PSI as the upper limit.

Do the neon colors fade?

The neon colors will fade when exposed to direct sunlight. We have added a base color to slow the fading effect, however, neon colors will still fade.

My unused fuel line has turned dull. What caused this and how can I fix it?

The dull finish is caused by the leaching of components used in the manufacturing process. Leaching occurs when the fuel line is exposed to seasonal temperature changes. To restore the shine, simply wipe the line with a clean rag and rubbing alcohol. Our fuel line should not leach when used regularly.
