I have a taco 007-f3 circulating pump on my boiler which stop working.
I searched for taco 007-f3 model but all I am getting is 007-f5.
Can I install a taco 007-f5 instead of 007-f3.

My initial reaction would be yes but I don't think I've ever seen an F3. Can you post a picture?

I am aware of the F-3 model, but it is a Taco 010-F3, not Taco 007-F3. The Taco 010-F3 model is 1/8 HP, the Taco 007-F5 model pump is 1/25 HP so I would be reluctant to recommend switching one foe the other. Look up the Taco 010-F3 (readily available) and swap for the correct pump... most likely, it was installed for a reason!
