Fuel sending unit

I ordered a new Fuel sending unit and by my mistake ordered a 3/8 inch but need 5/16
I have a 5/16 fuel line and can make a good rubber fuel line connection from the 3/8 sending unit to the5/16 fuel line. Will this work OK. I Like the new sending (3/8) unit it has a longer pickup filter bag then my old sending unit.

Thanks Tom C.

yes

Factory did it on A12 cars

Tom the biggest problem is gonna be if it ends up reading correctly. sending units are the worst of the worst as far as problematic new parts.
