Fueling efi and nitrous
im rebuilding a 92 LX. The motor is a sbf 302 stroked to a 342. Initially the motor was in an 82 all track time car running a demon carb running a 200 shot. When I started on the new project I switched to the fitech throttle body, and was using the fuel command center.
now that this is a fresh build on the new car I’m trying to make it more streetable and more of a sleeper type car.
my initial thoughts were to run a a1000 pump in tank into the efi and then run a secondary fuel system solely for nitrous. I’ve since scrapped that idea.
What I’m trying to figure out is how to plumb the system for both the nitrous and efi without using the fuel command center. I’ve decided on running the hyperfuel fuel cell rather than the stock tank. If I run the dual pump version can I run one line to the nitrous and one to the throttle body? Or do they need to be y’d together just for the throttle body.
Basically I need some help figuring out what is the best way to fuel both the fitech and my nitrous plate. I’m open to any and all suggestions
Just so we don't lead you astray, I would recommend you talk to your Nitrous manufacturer. They will likely have the best answer.
Scout 525, I am thinking about doing something somewhat similar to you but need to figure out if my hare brained scheme will work. I'm finally fed up with the FCC and I happen to have a Bosch 044 laying around. It's going to get used. I also am thinking about using one fuel system. I am planning on using the Bosch 044 and connecting it up to the Fitech unit. I will use another connection between another Fitech inlet and my fuel solenoid. I will of course have a connection between the return port and my tank. I found a chart last night on Nitrous Outlet's website that showed what fuel jet you would use if your fuel pressure was at 55 psi versus the normal 5 psi. The one question I still have is if this would work. Since the throttle body has the bypass regulator, wouldn't all of the inlets be governed at that 58 psi that the regulator is set at? Wouldn't all of the inlets be a fuel log at that point at the same pressure?
