Doo a deep dive in your area to find any wrecked 250 EFi, they would be great for parts. Daewoo uses an OEM black pump that has a different pressure rating (harder to find) , Delphi pumps are OEM Blue and have OEM numbers printed on them.
airbox EFi has port to slot in the ISC valve (idle speed controller) , and it sends 2 air pipes down to the throttle bodies.
The pump splits 1 fuel pipe in to a T-Piece which joins 2 smaller pipes feeding either injector (front + rear )
