I put a Walbro 255hp in-tank in my '83. It wasn't a "drop-in" replacement, and took a little customization, but it's been working for years.

No details, as it was done a LOOOOONG time ago.  I doubt I even have pictures. I know it involved a little cutting, some submersible-rated fuel line (don't cheap out here), and a hose clamp or two to keep the pump in place.

Is there a high flowing fuel pump for the 83 dual pump setup?  I have a 5.0ho with a stock 83 turbo coupe fuel system, at 5000rpm It seems like it just runs out of fuel won’t rev past that.  Do I need to change the in tank pump also or can I get by with just a higher flowing external pump?

Any idea how to run the fuel filter or maybe adapting one off another vehicle by swapping?  I do have a 255lph in tank pump from quantum it has the sock the submersible line the hose clamps and the wiring for it, just was afraid something might not  work by swapping over.

I have a 190 LPH Walbro intank pump in my car for over 10 years now. Plenty of fuel for a stock 5.0L HO and it's even quieter then my original factory pump.  It was a drop in kit with filter sock, pump, hose, and mounting bracket but I forget where I purchased it.  Are you still running factory ignition?  If so,  it may be breaking down at high rpm. Make sure your spark plug gap isn't too wide first though.
