I sell only brand new filters with the standard 14mm input for $9.95. 
Bosch only goes out when someone want a Bosch even though Bosch changed the
connector input several years ago. They don't work with out a lot of Teflon
tape. The loose nut design that Bosch went to just really doesn't work on
D's.

Look at the Bosch filter inlet. If you see a black plastic piece just past
the threaded portion, don't use it. The threaded portion of the inlet line
can bottom out against it restricting flow and causing fuel starvation. I
don't know if John is selling old stock or new for the filter. 
The low voltage ends up requiring more amperage to run the pump. This will
eventually burn out the pump. There have been several threads on this issue.
My particular voltage loss was mostly due to the crimped eyes on the wiring
harness that connect to the fuel pump. Years of messing with the harness had
loosened up the crimping. I got a new piece of harness and soldered the
lugs. Check your inertia switch too. Make sure the ground is good as that is
what the pump is grounded through. Does your fuel pump make a lot of noise
after the car is warm?  The high amperage may have damaged it if this has
gone on for awhile.  Not sure about your modified wiring. I've only ever had
2 wires running to the pump. 
If you are running the original pick up hose in the tank from the pickup to
the pump then you should replace it. They tend to collapse, starving the
pump, when the fuel gets warm. I was on the road when this happened and
stuffed a spring down it to keep it from collapsing till I got a new hose.
