question Zetor 5340 Fuel hoses diameter?

[djsumcp20oldleawharfcouk]

Are the injector return fuel hoses just push fit?
What size are these hoses?
How do you get access to the one behind injector pump?

I use fuel hose 5 mm inner diameter (3/16) 12 bar. Push on and clamp. I mannage to change behind the pump but am equiped with small hands.

I always take the exhaust manifold off as my hands wont get behind the pump.
