Oh boy, I am tasked with the challenge of replacing this fuel filter.

The van has about 300K miles on it and the other day it died while driving @ 45 MPH.
It has in the past stuttered, stumbled and then eventually came back around. This time it didn't and wouldn't start. It cranks just fine but no fire and the plugs are only a couple of months old and it has a new air filter. I did pull the upper fuel line off the filter, placed it in a container and cranked the engine. The container had about a cup of fuel after just two 5 second cranks. This leads me to believe it is not the pump.
-The rotor turns when cranked as well (I disconnected the electrical before cranking). Dizzy cap obviously off
-Tried wiggling and jiggling the key but no change. It's never had an ignition problem that I'm aware of.
-I checked all fuses and relays too.
So do you all think this points to a terrible clogged filter? It's probably the original or the second at best.
Before I forget, I also snagged a fuel pump of amazon for $18.00. Here it is:
Amazon.com: Autobest F4230 Electric Fuel Pump: Automotive I know I may not need it but for $18.00 I couldn't pass it up.
Any help or guidance is much appreciated. I do know about the crow foot 14 MM wrench and accessing from under and behind but it's still a major PITA to get at. Thanks in advance.
