there are no CONs of replacing any part that has lived its life.
get the fuel filter and pump replaced, u can decide to let the pump work for 40k more kms but u never know, it may decide to stop/reduce working after 15k kms n in that case u ll have to get the central console opened again, labour charges paid again bla bla bla... but u CAN keep the same pump.
i changed the fuel filter of my car changed at more then 170k kms. but that was on cng, not on petrol. i didnt get the pump changed and now its not working properly n im not getting enough time to get the whole procedure done again.
