Fuel pump help

[lateapex911]

I'm trying to reinstall my fuel pump ...which looks like this :

Backstory: Unfortunately, while sitting idling as I moved other cars in order to get my 911 in the shop to do some maintenance, like replacing fuel lines, one fuel line cracked and...a fire started. (SO close...ONE more minute of running~ to having them replaced!!!) I emptied 5 fire bottles and a 5 gallon bucket of water in a nearly comical effort to put out a fuel fire fed by gravity, and was lucky to minimize damage. However the fuel lines are gone between the pump and the bulkhead, which leaves me no example of how to replumb.

The pump, as you can see, has 3 ports, one large (about 10mm) and two others. I surmise the large is the supply from the tank, based on the fact that one of the hard tubes is about 10mm...so thats easy. (Looks like the lowest port in the pic above)

So.... that leaves 2 equal ports. One goes to the carbs, the other is, I presume, a regulated pressure relief return to the tank. But which is which?

In the pic, I can't tell where they go. Is the output to the carb on the outer part near the silver cap? or the center port?

Thanks for any clues! I've look at teh one Pelican sells but see no documentation.

Check carefully on the pump (by the hose attachments) as I believe they do have letters identifying which one is pressure(D for drunk), S for supply, and I believe R for return to tank.

I looked and didn't see anything, but will look again. Thanks for the code!!!
