If that doesn’t make sense please ask questions. I did the swap so obviously I’m competent haha. Thanks again.

If the Fuel Filter was totally plugged up or the central bolt was clogged fuel would likely not go into the fuel injection pump.
What if the lower O-ring on the central bolt on the Filter was gone or damaged and not sealing enough to let the fuel pressure go by?
The wrong filter bolt in the housing? There is 2 types of filter bolts for 2 types of housings.
Loosen banjo bolt 7 and pump with the hand primer and see of fuel comes out.
