Oil & Fuel T353 HST hard to start

[ND tractor]

I have replaced the bowl fuel filter.( which is not what the books say it is) This did not help.
Is there a second filter or a fuel pump just above the fuel bowl? It looks like a filter but has wires going to it.
I can't find anything on this. I even bought a manual. Very frustrating trying to find info on parts.

Good afternoon,
I would recommend having your fuel feed pump checked to ensure a steady flow is going to the fuel injection pump.
