Default 7.3 Fuel Leak on top of engine

Throwing this out there to see if I can get some help. Leaking fuel on the top of the engine and I have narrowed it down to the fuel cap. Questions are these?
1. Do I have to replace the cap or will the O-rings do?
2. Where do I get the O-rings?
3. Should the fuel heater be replaced also?
Look forward to the replies.

Put a new fuel filter in it, which will come with the gasket...

If that does not stop your leak then your drain valve is leaking and you can get a o ring kit for it.

Im with him just go to any parts house and get a filter because it comes with the O-rings rather than looking for the oring kit

All good answers out there. I had leaking issues and found that the fuel was leaking from the drain valve(yellow plastic body behind the fuel bowl). I ordered only the 2 o-rings for $10.00 from DFUSER Deisel Performance Products and replaced only the o-rings. Fixed my problem!

i've recently had these issues. heres what i had wrong.

Fuel bowl/heater/water fuel seperator had a pinhole in it, pitted from inside-out.
Drain valve on water fuel seperator was leaking from bad o-rings, ford sells the whole valve for 47$ rather than buying the o-ring kit for 35$.
O-rings on fuel line fittings leaking, replaced the fittings themselves because they have screens and check valves which can clogg, so i figured why not while im at it.

All good answers from everyone, im sure someone covered it here. just gotta clean everything up and look around
