The link below will show you the engine, and he also offers one the same but without the Corvette emblems on it. At 1/24th to 1/25th scale the fuel lines and such would be really hard to 3D print without them being really fragile.
I did find that AMT offered a 1/6th scale Chevy engine kit with the Rochester Injection setup on it, and it did include the fuel lines. You can try looking on eBay as there are a few sellers offering 3D printed stuff that don't have a website to sell their stuff.
