It took most of the afternoon, but I was able to get my fuel pump replaced with a new Walbro 255 lph part for $99. Contrary to the belief that you COULD chop a hole on the floor to access the pump in the future, I decided not to after witnessing the extensive mounting flange and fuel hard lines attached to it.
I concluded that the old pump was due for replacement after running a pressure test. It test at 35 psi at the rail, and the manual says it should be 40-47 psi at the rail. Also the plugs were burning white (lean) so I knew that was the cause of this issue. And the cause of the delayed starting and occasional stalling at low rpms. Plus, with 295,xxx on the clock I knew the pump was old and tired.
old compared to the new
i have an injector hanging open so it's time to Seafoam
