Don’t even bother buying aftermarket sensors.

If you do, you should ask the sensor manufacturer this question, not us.

If you don’t know how to reprogram them, don’t replace them yourself.

If you can’t put gas in without removing the white piece, then that confirms you should remove it.

Basic logic?

Don’t bother. It’s a piece of shit.

We can’t help with engine swaps. You have to have it looked at in person. Too many differences between the engine the car was designed for and the car it’s in.

He needs an actual swap expert, not us.

Get replacement washers. Have a shop put them in.

If that doesn’t work, have the shop look at the other metal parts involved in the replacement. Some may be missing rubber seals.

Also, wrong sub. Go to r/namethatcar or r/whatisthiscar…

No trolling here please.

Why not just ask the licensing people instead? Or the DMV? If you’re asking about a regulated vehicle why not ask the experts in person?
