Thanks for your replies guys
Here's what i've done today:
I've made fuel lines from 0.3mm wire. Obviously it proverd to be much more tricky than expected and most of it is hardly visible when the engine is in the car, but it still makes for a nice detail. I also added a braided hose from Ka models, but it seems a bit too shiny so I might wanna tone it down a bit later. Although I'm not sure if it's a good idea to clear cote flexible parts due to risk of cracking - anyone has any experience in this field perhaps?.
Until the next update
Cheers
