The high pressure fuel pump and cooler sits under the port motor mount and is a pita to change, it can be done just depends on the boat, a single will be easier

I said if your fuel psi is too high, then the screen is probably plugged. If the fuel psi is correct, then your screen is not an issue.

have you scanned the ecm ? to see if it points to a sensor .....ive never seen a stock 500 EFI without a lift pump,
