Technical Fuel hose help

I am trying to find some fuel hose that goes from 2 1/4 to 2 1/2. The tank side is 2 1/2 and the inlet side is 2 1/4. This is an off topic car. Just barely non HAMB friendly. It was stock but for one year only. I really don't want to have to modify anything. Can anyone offer up a source where I might find such a beast? It's only about a 4 inch chunk.

 

Can you use a steel exhaust reducer and put rubber on each end?

 

If its a hose that will not have fuel setting in it all the time could you use a radiator hose may not last forever but get you buy for some time.

oops that is silicone, NG for fuel...

 

If you can pull the filler neck out of the car either take it to a muffler shop and have them expand the end to 2-1/2 inches or cut a few inches off and weld on a 2-1/4 to 2-1/2 exhaust pipe reducer (available at most parts houses) Then you can get the correct gas filler neck hose and put it on and be good to go.

 

All good advice. Thank you.

 

I'd use 2 1/2" and put a piece of 2 1/4 inside the small end.
