Do I need clamps to install this hose?

Clamps are not included. You'll need hose clamps sized for 2.50" diameter hose — either worm-gear or spring clamps work depending on your fitment.

Can I use this for boost or fuel lines?

This is rated for coolant, vacuum, and intake air. For fuel lines or boost applications, verify compatibility with the fluid and pressure in your system before installation.

Does this hose need prep before connecting?

Wipe the hose ends clean before assembly. No paint or primer required. If you're replacing an old line, flush the system first to avoid contamination.
