I put a summit racing oil cooler in awhile ago, but on some of the barb fittings it is leaking oil very slowly. So I'm going to upgrade to stainless lines from Summit Racing. Anyone know the AN size for the fittings on the block and oil filter locations?

 

From what I've searched, the line near the filter is M18X1.5, what about the other one?

Bump, anyone?

 

are they the right fittings? i want to find an oil cooler that uses the stock style fittings.

but the stock fittings are banjo bolts. so why are you banjos leaking? no copper washers?
