Fuel injector return washers advice needed

[SiF]

I need some injector-expert advice here. When my injectors were returned they included my original return washers in a bag and new ones fitted. there is a huge difference in the design and I'm worried that the new ones will allow way too much pressure to build up! heres a photo with the old ones (with slots) against the new ones (holes only), should I use the new 'uns or will I live to regret it?


Many thanks

Simon

not sure if it makes any difference tbh.
i ordered new ones from my local mazda dealership parts dept.
part number PN1113G92A
think they were 1.50 each

Thanks @phoenixroxy, can I ask did you replace the shaped seat washers that sit underneath the injectors in the cyl. head as well?
