Max Wedge insane question

They sell scale fittings or you can make your own using small tubing and cutting it to make your fittings. Fuel block make out of square stock plastic. Fuel filters can be made using diodes from an old broken electrical board. Just remember take your time and if it don't look right just keep trying. I think these guys will tell ya sometimes we do it several times before we get it right. Good luck

Thanks very much! I have bags of junk music gear stuff (lots of good wires in there too) I can go through. Old junk cheapie radios also. To buy fittings & lines I'm a bit confused on all the different sizes, so scratch-built may be the way to go. At least I'll be able to size it up & rip it up if needed instead of buying wrong size fittings. My girlfriend makes jewelry so braided line, etc. is always around. I think buy throttle and carb linkage & fill everything in from there. Thanks again!!

I'm not trying to honk my own horn here, but engines are what I like to do the most on a model and I try very hard to get them as correct as possible and look as good as possible. Engines are not easy to do. It's great that you want to do engine work. The engine is the heart of the car and IMO it should receive as much care and detail as the rest of the model and some builders pass it by. It can get expensive using aftermarket part too. There are a lot of tricks you can use to get a good looking engine and save a lot of money too. If you look at my gallery you will see a lot of different engine styles using a variety of different parts.
One thing I would strongly suggest is don't try to learn too much too fast. It's very delicate work and can overwhelm you and get frustrating and blow you out of the saddle. Don't be afraid to experiment with different materials either. Remember your engine isn't going to really run it just needs to LOOK like it will.
I started out using the aftermarket machined nuts they make for models so I could get realism but they cost $10.00 for a package of eight and if you drop one it will vaporize and you will never see it again. I found that Hex beads work very well, come in many sizes and colors so you don't have to anodize your own, and cost $4.00 for 1,000. When I drop one I just smile instead of breaking something. On the engine below those are red and blue Hex beads on fuel junction block. The braided line is real braided line from Pro-Tec as is the fuel junction block. These are not expensive. I'll give you a link where to buy them at the bottom of this. I like to use Beaklon craft wire but this engine had small fly-fishing tubing for plug wires and fuel lines to the blower. Amazing stuff, I never dreamed you could get tubing that small. Comes in many colors and dirt cheap. The brass nuts on the fuel blocks to the blower and injectors are silver lined clear Hex beads I painted brass. I don't want to stretch this out too far so if you want to PM me I will try to help all I can. I still have a lot to learn but I think my engines aren't too bad and I would love to share what I have learned if I can.
You can get the braided line and fuel blocks here. Good prices and seriously good service. www.xtremescaledetail.com
