Finally put the back-up Mistake on the road,The fuel problem's back, only leaks when filled? Let me explain, the fuel pressure delivery and evap system are just fine. However the ports externally leak and the top of the fuel pump plate. I talked to Dom on the phone the other day and he had never heard of one leaking there? Had to replace a whole unit of course, shame the pump itself functioning properly but because of the fuel port seal between the top plate and the ports. Am I making sense???
Luckily the dealer gives me a 30% discount or my cousin actually. Same price as Jenkins in Nevada. Still frustrating though Especially 6" plate and the floor opening same as early Mistake what 4 1/2 plate. PFS 216 vs PFS 214 only difference is the plate that I can see. Good ole airplane snips - Oh Dom, I had to pop rivet small 2" piece of the metal across the cuts. I realize as you said not a structural area but a left over training from the Ole Marine I guess and own military experience in Korea 1968. The thought of several 100 of thousand North Korea soldiers swamp south, it behooved us to kept a vehicle running perfectly.
Any idea the real reason for plate size or is that hole in the tank size change? Must be something to do with bean-counters and maybe commonality and other Ford vehicles. $$$$
Oh Terry I remember something about the Detroit engineers didn't like you Ford of Europe engineers telling them how to engineer!!!! I wonder if that animosity still exists Terry? Human nature!!!

The floor hole/pump sender unit size had a change late in the production runs and there was a mismatch of sizes so some cars needed the floor cut to remove tank and sender..or drop the tank.
On this leak,do you mean the plastic quick connects are leaking wher the plastic 90 deg elbows go in??? Bit lost exactly wher the leak is ...??

Yes Terry this is confusing, it only leaks around those ports when tank is full. I don't see any way to fix since raised piece steel is spot welded to large metal round plate. If I could have the pump in hand it would be bit easier to say here EH? Oh there does appear to be piece to rubber between the raised piece. I'm assuming this is where the leak is eminating? As I think I said before the actual operation of fuel delivery does not leak. I'd try to some of the Brit slang I've picked up from talking with Hams in UK however I haven't the foggiest how to spell most of those terms?

..OK,it sounds like this is not a pressure leak from the actual connector but from wher the connectors body is sealed into the steel cap of the pump and send unit.Maybe,with a low fuel level, clean off around the connect to cap seal and try a bit of black Si gasket sealer and let it fully cure overnight..other than that it would have to be a new pump/sender unit..If you can't get it to seal then don't take any risks with gas fumes etc..replace the unit...
