97 Chevy Blazer 2door filler neck rubber hose size

1997 Chevy Blazer 2-door filler neck rubber hose sizes?

I am in the process of ordering a replacement fuel tank filler neck for my 1997 Chevy Blazer 2-door. The filler neck for the 2-door model doesn’t come with the rubber hoses or hose clamps like the part for the 4-door model. I was wondering if anyone out there knows what size rubber fuel hoses I would need to purchase to replace the rubber hoses that go from the filler neck to the fuel tank. I could measure them but, I haven’t had a chance to climb under and look. My hoses are still intact but, I would prefer to replace them since they are older and getting kind of dry rotted. Thanks in advance!
