Screens in fuel line

Does anyone know if there are any screens (other than the spin on filter)in the EFI fuel system on the 8.1 MERCRUISER Horizon
We are experiencing a restriction similar to a pick up tube tube clogging .however there is no screen or siphon valve at the fuel tank pick up tubes on Sea Rays in2002. They use an electric solinoid instead

There is one in the fuel pressure regulator on the fuel rail if your year has one. There is also one on the CF2 fuel pump and the FPR next to the pump.
