2.50" to 2.75" Silicone Reducer Hose 45 Degree 3-Ply Black

What size hose clamps do I need?

You'll need two clamps — one sized for the 2.50" end and one for the 2.75" end. Standard worm-drive or T-bolt clamps work fine. Measure your existing hose diameter to match the clamp size, or bring the reducer to your local parts store for sizing.

Can this handle fuel line pressure?

Silicone hose works for low-pressure fuel lines and return lines. If you're running a high-pressure mechanical or electric fuel pump system, confirm that your pump's PSI falls within silicone's safe operating range — some fuel pumps run hotter and faster than silicone can handle long-term.

Do I need to do anything to prep the hose before installing it?

Straight out of the box it's ready to mount. If you're installing over barbed fittings, you can dip the hose ends in warm water for 30 seconds to soften the silicone — makes sliding onto fittings easier. No sanding, cleaning, or priming needed.
