Here's a pic of the area on my Hemi.
Top with air cleaner removed.
The fuel line is right against the vacuum advance diaphragm but it did fit. I stripped the chrome off of all the fuel lines and the vacuum line with oven cleaner so I could sand off the seams and then painted them with Alclad II "Stainless Steel".
Do a search on "Testors Hemi" here and on Scale Auto's web sites and look at those threads for hints and tips. The most important one I got from these sites was that for the o-rings the kit uses as the fan belts and the main drive belt. The instructions will have you breaking the power steering pump off when they tell you to put a too-small belt on.
I have posted more pictures in another thread, if you take your time it comes out nice.
