Bruce,

I think most of us with LS engines have had custom ones made.

Shaun made my one up, and it is brilliant. I am filling via the heater hose outlets. (Car is not running yet, so not sure how well it works).

Make sure you can bleed all of the air out - others have had problems with overheating if there are any high points in the system.

Cheers,

Ben
