Here is a picture of the fuel filler I have prebuilt for the future GT-R. It uses the same C6 Corvette fuel filler assembly as on my SLC but I kept to a 1” filler pipe. At the fuel tank end I have a 1” to 2” adapter and the 2” Perko check valve Inside the short 2” fuel hose.
Just make sure that whatever year tune you use as your operating system that all parts are pulled from that year. IE…..the ECM, FPCM and EVAP system parts.
From your picture I see that the vent control solenoid is independent of the canister…..:)
One solenoid should be at the engine and the second one will be back at the fuel tank near the vapor canister. Perhaps the second one is also incorporated in the vapor canister. I will investigate this further.
The E-Rod is what I meant instead of, as I called it, connect and cruise.
It all depends on how far you want to take the evap system. The connect & cruise system as sold by GM uses a vapor canister and the solenoid that is attached to the engine. The solenoid opens based on different parameters (like fuel level) as you mentioned. When the solenoid opens it is creating...
Keep in mind that you still need to install a fuel pressure sensor in the top of the tank. It measures the vacuum in the tank when a leak test is commanded. You can see in the second picture that the plate to hold the sensor should be about 5/16” thick.
Mark can you remember the product name/number for the Click Bond adhesive? I see Click Bond CB420 mentioned with Holley but when I look at Click Bond data sheets CB440 is the one used for fuel immersion (polysulfide).
I will be modifying a GT-R tank soon with a couple of different pick up...
