Installing fuel filter after the pump is a bad idea. From experience on
boats I know that the electric fuel pump will atomize water and push it
trough the filters. In diesels the water will blow the tips off the
injectors.
One boat had to repair lots of engines for that reason.
I do some work for a German diesel fuel filter company, and they always
recommend the filter to be mounted before the fuel pump.
BTW on best practices page, the wrong set up is recommended?

Normal aircraft practise is to put a filter after any pump. Especially in
the configuration all the 13B's are operated in Tracy's suggestion is sound.
Everyone is running twin injector pumps in parallel (or are there still a
few carburated 13B's flying?). A screen at each tank fitting, a coarse
filter after the tanks (preferably combined with a water trap), with a
filter after each HP Injector pump. If you run the filters before the pumps,
a single pump failure will cause an engine failure due to injector blockage,
negating the redundancy of dual pumps.
