Since any in-line fuel filter installed prior to the mechanical fuel pump is an aftermarket item it's possible to suspect the in-line filter may have been installed incorrectly? Since there is no indication of the product number &/or manufacturer stated in your post, I'd suggest you examine the in-line filter to ensure it's installed correctly. Generally, I believe there is an arrow on most filters indicating flow direction - was it installed backwards?
A leak in the fuel line between the tank and this aftermarket filter could hinder the pumps ability to draw fuel from the tank and instead pull air in through the leak. There are a few places where the factory used a short length of rubber hose to get around corners (tank pickup to line and through the frame behind the RF wheel are two places that come to mind). The aftermarket fuel filter is another in your case. I'd start there.
YES to this! Try blowing compressed air through the fuel line from the engine side back to the tank. Sometimes the sock in the tank gets saturated with crud and stops the flow. I did this trick on a few project cars. Once the sock is off, the filter will catch any chunks that get sucked up.
So, yesterday you replaced the mechanical fuel pump AND the in-line fuel filter prior to (downstream of) the mechanical fuel pump. You are aware the mechanical fuel pump DRAWS (SUCKS) fuel FROM the fuel tank, correct? If you disconnect the fuel line running between the mechanical fuel pump and the fuel tank AT the fuel tank does fuel flow from the fuel tank?
Put a few gallons of fuel in the tank, just to be sure.
Fill the float bowl of the carb with gas, the engine should run long enough on that to pull fuel from the tank. If it still won’t start, id look at ignition failure.
If it will run on fuel in the carb, but not pull fuel from the tank, inspect all the lines for holes or split hoses. If good, either pump is junk or the fikter in the tank is clogged.
