Fuel Lines Routed

I finally got some work done on the fuel system. First, I ran the AN hose under the frame and connected it to the driver tank. Then I ran the 5/16″ and 3/8″ lines that connect the hardline crossovers to the tank. Finally, the sensor was plugged in.

Moving on to the passenger side (much tougher to work with due to very tight space (all the wiring), I set the fuel filter into place (haven’t installed yet, waiting for a new one to arrive) and mocked up all the lines then cut and fitted them as needed. Once the car is ready for fuel it will only take a few minutes to connect all the lines up.

I also applied weather strip to the tanks/frame points where there will be rubbing and contact.

    Hi again,

    I was just curious as to how you hooked up your EVAP system? Thats got me stumped completely. My donor car was more of a donor rolling chassis and none of that was hooked up to begin with so i couldnt make a record of how it was done originally. Do you have an pics of your EVAP system?

    Thanks, Tom

    Hey Tom-

    I did not install the vette EVAP system as my state does not have emissions testing. If yours does not have testing either – skip it.

    That being said, I can tell you how the EVAP system is all connected. I’ll start at the evap canister – that’s the big charcoal filter box. The bottom of it has 3 ports – Purge, Tank, and Air. The Air port may have a rubber cap on it. The purge port is connected to the evap canister purge solenoid via a hose. The purge solenoid (part #1997251) is routed to output into the intake manifold via one of the vaccuum tube ports. Going back to the cannister. The Tank port connects to the top of the fuel tank at the rollover valve. This is by the fuel tank pressure sensor (FTP). The Air port on the canister runs to the evap canister vent solenoid (part #10293954). Each solenoid gets their respective wiring plugs. The bright red one goes to the purge solenoid. Hope that helps!
