[C320-list] exhaust elbow question

[Koen Bennebroek]

Thanks to all who replied. It sounds as if it will be a good idea to order a replacement elbow. For those that have the Perkins and have ordered this part, could you provide me with the exact part number? I found some part numbers on the catalina FAQ, but there is no mention of the elbow part number. My mechanic also mentioned a gasket. Does that come with the elbow or do I need to order it seperately?
 
Regarding the in-line fuel filter (which is currently leaking on our boat so needs to be replaced), what's the difference between the Racor R24S and R24T listed in the FAQ?
Are there any other parts I should expect to be replaced during the service? (apart from the obvious like impeller, oil and fuel filters).
 
Thanks a bunch again for all the excellent info!
