That's the fuel heater, and it's a fairly common spot for fuel leaks and air intrusion (the reason it's hard to start first thing.) There are 2 (IIRC) O-rings around the beige plastic part underneath the filter head. Remove the filter element, fuel inlet and outlet, and any hoses and wiring, then unbolt the filter head. The heater is held in by the filter nipple, remove that and you can pull the heater out. Install new O-ring(s), lube with Vaseline, and install the heater. Assemble everything in reverse order.
