Also make sure to replace every rubber hose that carries fuel under the hood. The lines from the fuel rail on the firewall to the engine feed rail, from the feed rail to both left & right rails, the 8 injector hoses, and the lines behind the rails to the return. Use EFI-rated higher pressure hose, 7mm IIRC. Ensure the flex disc that attaches the trans to the driveshaft is in good shape before driving as well.
