Car threw two codes what to check?

All this happen right after i changed out my fans to the dual Altima fans then
my 1995 240sx threw two codes,

34- knock sensor
76- fuel system

I dont have a service manual, and was wondering where the knock sensor is

Since there is so many components for the fuel system what should i check first?

theres a fibrous screen on the fuel pump in the fuel tank, might be clogged after 11 or so years.
