My power steering pump is leaking on my 94 sti,ive been to subaru & they sold me 2 different 'o' rings(because they said they didnt know which 1 was ****!). The part numbers are 31266ga020 (20mm in size), & 34427aa020 (13mm in size). they gave me an exploded diagram,but i cant find the part numbers on it! I just want to know if i have the correct 'o' rings.Someone plz help me.cheers

No idea...Take the pump appart....why go to subaru...did they charge you pounds for o rings that cost pennies...build great cars but you have to be smart to keep one for cheap!

 

'o' rings cost just under £3,but at least i know they were the right ones. But now i know the correct size i wont be going there for them again! Just for the record the lower 'o' ring is 20mm & the upper 'o' ring is 13mm. So if anyone else has this problem dont go to the dealer!!
