Default Throttle Body by pass

The brass orifice and weak weak plastic part has been leaking since my wife bought this truck. Bought an Amazon A premium hose and I can't fit it for love or money.

I have a disco 2 and did a bypass and she starts in all kinds of weather whether it's- 30- 30 or + 28.

I want to do the same with this truck but I'm trying to figure out the coolant flow and looking for information on how to close the loop without having to use the brass orifice as I cannot get anything inserted into that freaking thing. TIA

Disco 2 owners like myself by pass all the time.. Not much on the LR4 forum... AI has provided this: take the hose off the left and tie it into the hose leading to the expansion tank. Then take a new hose and connect it to the hose barbs on the throttle to be a loop. The problem is the brass orifice.... Not a lot comes out of it but it comes from the rear but must be plugged. Tap a plug? JB weld a plug? Decisions. Any comments? .

Default 3/8 fitting, tapped, with high temp sealant and black hose fit perfectly.

I don't get the bypass. Could you take a pic of the final results to clue me in?
