The first one is just the injector o'ring seals. can buy new from toyota. don't need part numbers. Just get them to look it up on there listing. they'll be able to help you out.
As for the second same deal if its between the injector and fuel rail and it is rubber, its just the top o'ring/injector spacer.
but if its hard plastic and is between the bolt up spots for the fuel rail. they are just the fuel rail spacers.
If toyota can't help you out which im sure they will be able to as i've brought new from they and just got them to look up the listings, i can help you out buy giving you part numbers.
I'll just need to sort through my invoices to get the part numbers. so let me know if you need them.
