I'm looking to renew the injector inserts on my '90 valver. ETKA lists 2 different part numbers with no explanation why.
1 - 034 133 554
2 - 034 133 555 A
As usual the illustration isn't too clear.
Also, there are at least 3 different types of seal listed, again with no explanation for the difference!
Anybody help with this?
Thanks in advance as always,
Duncan
