MAF Screen in Factory Airbox - Should this have a seal?
My car is a 2000, stock intake and noticed that the MAF Screen/Strainer which is sandwiched between both sections of the MAF housing sits in there loosely. Loosely as in, it's not going anywhere but has enough room to slide around a bit.
If I unbolt the MAF from the airbox there appears to be a 'notch' or ring seal area in front of it but no o-ring or seal. Should there be an o-ring or seal in there and would this affect anything with the stock intake otherwise? I've seen some used MAF units on ebay and noticed a few of them have what appears to be a gasket or seal of some sort in front of the MAF surrounding the screen.

I looked all thru my Mitchell subscription and there isn't a single diagram of the MAF or how is mounted. My son has the car now, so I can't check it out and I don't recall when I had it out to clean it.
Sorry, I am useless this morning!

it should not move around, if it can move its leaking unmetered/unfiltered air, if you go to a dealers parts dept, they should be able to pull up a diagram so u can see the associated parts and get what you need

I've tried searching pics of the stock MAF/screen setups and the only thing I can relate to is some used MAF units listed on ebay and some show a sealing 'ring' around the screen and some don't. I've carefully taken apart the airbox when I first got he car and never noticed anything falling out of there.
For reference, here's the only one on I've found online that shows a seal around the screen attached to the MAF.

Did a quick search of Ford's parts catalogue, and it appears they list what they call the MAF o-ring or gasket, but it's $83.00!
I can only assume that's for a bulk pack of 20 of them lol. I'll check with a local dealer and see if this is even still available, but at that price might as well source a used one somehow.

I think I may have found a solution:
I came across some old stock of 3M double sided tape I've had laying around and it gave me an idea. I cut it to length to fit around the screen and then folded the edges over. The screen still fits in the beveled area of the air box and I was able to carefully tighten the MAF down and looks like it's created a nice air tight seal. Once I get a chance to road test I will report back.

I wouldn't worry too much over this. The screen is just in case your air filter comes apart (it rarely happens, but does), or you drop a nut into the intake -- it protects the sensor probe from any FOD which might be drawn up the intake at high flow.

the op wasnt worried about the screen, but rather the missing seal in that area that was allowing unmetered air to bypass the MAF
