I'm more looking for suggestions to my current approach. Fuel system 1:1 detailing can be frustrating due to the scale when building 1/25. Especially when you invest in RB Motion AN precolored fittings works of art), but working with them and .025 braided wire is insane! After my first encounters today, here are some suggestions and I'm looking for alternative viewpoints.
I ran .035 braided line from the fuel cell to the engine bay. I used and xacto to pre-drill small holes for the fittings to go into. Here are the specifics on the fittings (yes I should have taken pics; however, what they are like:
,
If you look at the pieces on the far right, you'll see the red piece has an opening for the braided line and the other fits into the pre-drilled hole in the carb. The blue piece fits as show; placing it on the tube before gluing it. First, I'd recommend getting one size larger than recommended for your braided line. If RB recommends the fitting for .025 line, get the fitting for .035 line. It will give you an easier time getting the fuel line to fit into the red fitting and it's just plain easier to handle than the tiny .038 fitting used for .025 line.
So I also learned that I personally don't have a reason for using a 90 deg angled fitting; straight is easier to use and if you have a circumstance where braided line won't bend as tight a circumference as you need for a carb setup, you might look towards bendable aluminum or rubber line as many modern racers are anyway.
Mistakes and bad eyesight wiped out my entire purchase of nearly $30 of RB Motion fittings although I still managed enough to complete a 2 carb setup. The next build is a flopper and I'll see what's period specific for it; however, my Showbox Ford will be scrutinized to see if some really thin styrene rods might allow me to some alternatives. In any case, check out ProTechs fuel block distribution setup on Teds site to see if you can use it as a template to make your own: protechmodelparts.com/carpartspics/ptmc61.jpg You can also try this T setup to bring in one line per side of carb pairs and split the line to feed both front and rear carbs (do this once for both sides of the carb!): protechmodelparts.com/carpartspics/ptmc63.jpg
Hope this makes sense!
