In reality however, this is most likely due to the fact that operators know which jets contain faulty part, so the Brits paused flights of said fighters, while the Israel is likely playing it safe and double-checking evry jet.
Also, I find it impressive that they managed to narrow it down so precisely - I suppose such fragile part as fuel line must have been surely destroyed in the crash/fire? Meaning they must have uncovered the cause due to ALIS, not pilot report or crash "forensic examination"?
