Tool for inserting nylon lines into WUR

[prebordao]

As some of you know inserting the nylon fuel lines is a PITA.
Faced with that prospect again, (for a new WUR), I decided to try to replicate the factory tool using wood.
It was a quick thing to do, and it really worked 1st time.

1. Attach firmly the line inside the wood "sandwich", using the screws
2. Place WUR on a vise
3. Hold tool in position on top of WUR
4. Deliver 1-2 hammer blows on tool
