Bulent,

   I have a Cosmo 13B . There are Metric to AN adapters that will replace the banjo

in most if not all cases. Both the engine and the oil coolers. May take a little hunting

but probably worth it as the banjo fittings are restrictive to oil flow. IMHO

 Jump in here guys! Any other opinions?
