None of the other sensors that get replaced during an EGR tuneup are used after a demandate. Do a fuel system leakdown test every 3 months or so to keep tabs on the system, and rebuild your fuel pump at the proper intervals like you mentioned and your good to go.

Should I still replace those two about every year?
