Default Help with Blown Coolant Hose XKE S3 1973

Hi, one of the coolant hoses on my v12 has blown. It connects from bottom RHS of engine and seems to route to bottom of radiator. I've checked all the parts providers but none of the hoses for sale match the dimensions of the broken part. maybe this is because the previous, now retired, mechanic used some hoses that weren't jaguar v12 specific. I want to make sure i'm ordering the correct hose or group of hoses. Would anyone have a diagram or drawing that would show the connection sequence for these lower hoses? i've looked at a bunch of hose schematics, but they're not seeming to be totally accurate for my situation.
any help much appreciated.

thanks mxfrank. i see the code for the furthest hose on the right has been rewritten as GRH540. This is a different shape (mainly in length) compared to the C number that's crossed out. I see that O'Reilly's has/had this part (below). Would you know if this is a common substitution for that original C41091?
