Basically the only real changes were adding an electric inline pump, directly after the selector valve, along with the supplied pre and post inline filters. My return side was rerouted down the back of the engine and bell housing and over to the frame from there. And thinking about that, it means that the factory hard line on the frame is now pressurized from the electric pump, where the stock mechanical pump would siphon from that hard line in the past.
Thinking that with the decent AFR's of the Fitech, it is likely that my EGT'S are slightly higher than the pig rich carb. I'm also using manifolds and a y-pipe from a 90 TBI burb, they may be different enough from my old headers and from the non-TBI exhaust that maybe the combination heats up that hard line as it sneaks by the shackle mount on the passenger front. Factory TBI trucks route the fuel lines up the bell to the back of the engine, not along the passenger front frame like the carb trucks.
