Looks as though the problem has been sorted out for you.
One thing I've learned is how to replace hoses on my Perkins Marine engine
never built a marine engine
but jobbers would buy bear Perkins 4 108 engines and marinise them and sell them as a "Perkins 4 108 Marine Diesel".
When I had to find hoses the Perkins mechanic
said to go along to an automotive outlet and have a look at their rack of hoses, go through them with a vernier until yo get them with the right bends and right diameter. "Sometimes you might have to cut 6 inches out of a 2 foot hose"
. And that is what I did.
