I am smelling gasoline
It is odd, at start up I have a strong gas odor in the cabin. It seems to go away as I drive. I can smell gas in the engine compartment which I assume the cabin air is being drawn in from there. I can't see any leaks. I did have to replace the hose that runs from on fuel rail to the other recently, but that is not leaking. Everything seems tight, but the gas has to be coming form somewhere. I am kind of afraid to drive it until I can locate and fix the source.

ok. this is the kind of thread that is often followed by - my truck caught on fire...
so do 2 things -
don't park in an enclosed space, such as a garage or basement, period. many of these have gas furnace or hot water heater or even an elec light switch spark = boom.
fix this asap.
it could be injector o-rings.
could be the quick connect at the rail.
could be a soft hose
could be a hard line
could be the top of the tank fittings.
could be a vac line or component in the evap system.
check your high pressure lines from/to the tank/injectors first. those are the one's that are going to burn the house down. the evap system is less dangerous.
i don't know if this exists or not, but if you could put air pressure on the system, you might could trace the whistling sound. otherwise i'm thinking the truck has to be running to maintain its 49 psi

I asked several different sources including dodge parts and service depts. Most just scratched their heads and said they didn't know. There is no part in the dodge parts catalog for that hose. A dodge tech said that it is just regular fuel line so that is what I replace it with. The OE set up doesn't use hose clamps, but has some very serous barbs on the rails to keep the hose on. I had to split the old hose to get it off.

if you don't have clamps on that cross over hose, you should. it likely ? had a crimp of some kind on it from the factory. you should have a good solid hose clamp on it. that line would have 49 psi of fuel pressure on it....
by the way, when the ignition is turned on, the fuel pump comes on, and you'll have high pressure. if the truck cranks and runs (as determined by sensors and pcm), then the fuel pump stays on. if the truck dies, then the pcm sends a signal to ASD to shutdown the fuel pump to prevent fire. assuming no leaks, pressure remains on the system. pressure can be relieved at any time by pressing down on the schrader valve. a little fuel will squirt out when you do, so don't be smoking.
