I Hate To Ask A Fuel System Question...
Ah. Alex was wanting one for his RR, so I'm sure he'll be bummed to hear the b bodies are getting left out for now.
The system I have now works great. I've had troubles only related to proximity to the muffler (my fuel system components are right between muffler and body). Make sure you get the fuel system components as far away from the exhaust as possible and use heat shielding and it will work great. B bodies have a lot more room to work with, so you should be good.
