silverado fuel pump/sender fitting

[t300]

On a factory in-tank pump feed and return from 2001 silverado, can I use either of these fittings *on the sender*?

I used the Russel part on my fuel rails and worked fine, and I liked the threaded retaining cap. Now, I'm going to ditch the inline Walbro and sink the 2001 pump into a rear mount tank. Will the Russel piece work right on the sender as well or do I have to use something like the Tanks Inc fitting?
