OK to use 11T pulley in place of 10?

Got some 11 Tooth rear derailleur pulley wheels, not realizing the old bikes I work on have 10T pulleys. Shall I use them or return them? Any plusses or minuses in how they function?

I did find a budget solution: 5/16" I. D. fuel line. It works very well and is very secure. I'll leave it on until the ebay real Campy covers arrive. Maybe even longer.
