Hi Emily, 
try the tapatalk app, it's free and you should be able to attach a photo easily with it.

i vaguely remember something like you are describing, but has been ages since seeing one.

what's wrong with it? they probably assist in warming up the engine or other pollution gizmo. 
@SPArKy_Dave may have an XF in his museum with that hose
or @Jewing15 is about due to update us on Her XF wagon which is a similar model and quite orignal, may be able to show a photo for us

Sounds like the pulse air injection, puts fresh air into the exhaust to make it seem as though it runs cleaner, the plastic things are valves that prevent the exhaust gases entering the air cleaner if I remember correctly.

I've decided to go with a Holley 650 double pumper and extractors , 2,1/2" straight pipe w sports muffler .....

@CHESTNUTXE might give you some tips, i wouldn't have thought that carby would be a good match without some decent engine work. 

unless you are doing a lot of engine work at least.

465 is a perfect match for a warm 250, don't go off CFM rating for the 2-barrel carbs, they're not rated on the same scale as 4-barrels.

A 350 2-barrel is really about 280 and the 500 is about 360. A 650 DP like Dean said is a bit big for that engine, might require a bit of work to get it running right.

Good rule of thumb I like to use is take the target HP and double it for the required carb CFM. Realistically, a healthy crossy would be in the 200-220 HP range without major work and lots of know-how. With this in mind, a carby between 400 and 500 would suit best.

There is a 4-barrel Edelbrock 500 that might fit the bill:

Going to beat everyone in to it, make sure it’s a standard volume oil pump not high volume !
