Default need Info on Ver6 fuel control

Does the Ver6 have a Fuel pump controller? I've looked thru my wiring diagrams and I don't see one. But I'm running rich enough to bog my car down. Just trying to cover all my bases.

Any ideas why it would be running so rich? I officialy have all the proper sensors (Thanks to Grade A Subaru) and a 80mm MAF housing. I'd be running lean if I had a vacum leak. So what's next on the list for running rich? oh yeah, I'm not getting a CEL.

What maf housing and sensor.....is it a Ver 6 housing?? Those are the only things that will make you run very rich. Temp sensor should throw a code if its bad. Fuel pressure problem is pretty unlikely but possible.

I am concerned the MAF sensor isnt sitting correctly in that housing, any pics? Did you measure the inside diameter of the housing?

yeah I measured it and it's exactly 80mm. But I have been browsing some UK forums and they are say 99-00 is 90mm. And that would explain alot. Running rich and also the high idle. with no CEL cuz nothing is really wrong...per se
