$30 harbor freight fuel pressure regulator has the right connectors. Def test.

The FPR is in the fuel filter, so not sure what you have? Swap the O2 sensors..it's easy, get the small socket wrench attachment on Amazon for $8. You don't need the entire kit, just the one tool.

I’ll look for both thx!

Meant harbor freight fuel pressure gauge tester. Not a regulator.

I figured as much.

After comparing prices I ordered OE Bosch sensors from Amazon (and pretty sure they're not even counterfeit!). Usually FCP is my go-to but these were for all four about $75 less.

I got the tool kit with two sockets, two different crow's-feet and thread chasers. Which would you suggest? Seems the sockets might spread open if the old ones are really stuck. Figured after spending that much on the sensors I’d get the tool kit as well (returnable even).

It's not going to spread open. They are in tight but not that tight. Just break them loose and spin them out by hand, put in the new ones. Just change the precat ones, easy to get to. Takes about 15 minutes. You are wasting more time fretting over this. Get on with it. I've put on 3000 since swapping, car running like a dream. 237,900 miles. Drove literally 6 hours in hell traffic yesterday. Another 150 miles today. I'm redoing all my door cables and handle carriers. Got new tires and and reglued my headliner. This puppies ready for soccer travel season!

Put a hose clamp around the crow foot. Also: for post cat: remove the vibration damper for much better access on the downstream sensors.

I use the crow foot with a wobble extension from below (extension in the opposite normal side) it works like a charm with impact wrench to start it.

You can also use a hammer on crow foot if don't have impact.

Does a Ford O2 sensor tool fit BMW sensors?

I've used mine several times on other vehicles. A cheater bar or mallet help too.

What size O2 sockets does a Ford O2 sensor use? AFAIK or AFAIR, pretty much all the O2 sensors I've ever changed (or likely to change) will have used 22mm O2 sockets.

I just checked, on RockAuto, multiple O2 sensors for my '01 BMW, my wife's '14 Lexus ES350, and our three old ('98. '04. '09) GM trucks, and all use 22mm. I also checked a few Fords at random, and they used 22mm sockets.

I got a set of thick-walled BLACKROBOT 7-Piece Oxygen Sensor Socket Set on Amazon Vine, and they feel like there'll be no stretch nor give in them, made of thick-walled CRV steel. The set has a 1-1/16", a 27mm, and a 29mm socket, as well as four 22mm sockets: a 2.75" deep and a 3" deep std. socket (I don't have a metric measuring tool handy), a 1-1/4" deep and a 2" deep crowfoot pair.

I figure that it's better to be ready beforehand, so I picked up this set when it poped up on my feed.
