Having just installed that on a 5.7 TBI, the factory fuel line needs to be shortened and re fitted. I ended up using 6an fittings and hose. A spacer under the throttle body helps too with clearances.
Once I installed it, I found only 8 psi of fuel pressure when I should have 14 psi. I also found only 8 volts to the fuel pump, I am chasing that stuff now. I suspect the wire was overheated from a bad fuel pump causing a voltage drop. I plan on running a new 12 ga one.
