Gates22826 Lower Radiator Hose

What is the hose diameter? I want to use new hose clamps when changing my radiator on my '02 Camry.

Amazon has two advertizements for gates 22826 lower radiator hoses.one for $8.23 & the same hose for $14.52.why the big difference in price???

Is this part for a 2002 toyota camry xle 4 cylinder ?

Does this fit 2004 Camry with a four-cylinder engine
