The fuel leak seems coming from the square parts with 3 fittings. I am little scare to removed everything. May I have some advice about it. It have something to do with timings

To identify exactly where the fuel is coming from clean the area with a good cleaner(like brake fluid), let it dry, then sprinkle some powder (like baby powder) and watch where it gets dampened first.

May just need to snug up a clamp, or fuel line.

It looks like someone has messed with this hose and clamp…. and it might be leaking as the clamp does not appear to be properly placed. (too high/too close to the barb)

I did put some powder to find leaking place after hours to let the tractor idling no sign of leaking. Next morning see the pictures.

I voted yes, but I couldn't tell you where the yes is located.

I don't like those springy wire clips because they lose tension after awhile.
And after the hose gets crispy with age, they leak.
But, is it possible that the injector connections were turned? (see arrow)
Maybe loosened enough that they leak?

The dealer mentionned that I should not unscrew anything because of the initial motor timing.
