Take a pic or do one at a time. Fuel lines are measured in mm by the internal diameter. I think the 105 uses 12mm. The older model 7* series were 8mm. Take a sample with you.
All fuel hose is fuel hose, no separate hose for petrol and diesel ect. I like Goss brand hose
Have rags and a container to empty fuel into, sounds easier than it is.
Once back together, you have to bleed it . Draw fuel to the fuel filter with the hand pump. Crank it for 15- 20 seconds, then give it a hand pump until it goes hard and crank the engine. It will run rough , pump the hand pump will help it smooth out. Usually they stall and you need to try again.
Once they are running on 6 cyls they will bleed the last of the air out.
If you have replaced the filter, the starting procedure will be the same.
You can possibly add a prefilter to your existing bracket. I got a proper Toyota pre filter with double bracket and filter for $20 at a wrecker. But lots of aftermarket options out there
