Power steering leak at pump

[Deanmc]

Well lads, got a power steering leak coming from where the lines go onto the pump via a plunger looking thing, have replaced the o ring with a genuine Toyota part and it still leaks, anyone have any fixes for this? Anyone tried a copper washer in there aswell? Worst case scenario I’m gonna swap the lines and pump over from my breaker Glanza. Cheers

I'm not sure without looking, but that could be a taper seal hydraulic type fitting so wouldn't have an Oring?
Has it been overtightened and cracked either the fitting or the pump body? Would only need a hairline crack to leak.

I had a quick look on toyodiy and couldn't see the Oring you spoke about? Do you have the part number? Maybe it only came on specific years?
