Evap System Setup??

[Scott2]

I'm trying to sort out the Evap system setup on my LS swap and have a few questions. Hopefully, someone here has a much better understanding of this than me?

I have 5.3/4L60e out of a 2004 Tahoe, I am in Colorado and plan to use all the Tahoe emissions to stay legal. Most of the emissions I am OK with, just trying to get the Evap system straight in my head and there are a few things I'm confused about. I did not get a canister with the motor and trans so I pulled one from an '03 Silverado.

First question is the fuel pressure sensor. I can either buy one as a replacement or grab one at the U-Pull. What I'm not sure about is how to set it up with an older, non-Chevy/no evap gas tank. I will buy an in tank pump to handle the EFI, but where do I mount the sensor? I think I saw a comment on t-ing it into the vent hose but what do you use for the mount or bung hole or whatever they insert into? I suppose If I got the right sized T I could just insert the sensor into a short length of hose the right size stuck onto the T? Attachment is a hose diagram from another thread but looks right for me.

Second is the fuel level sensor. I believe I saw a suggestion to use the Tahoe or similar fuel sending unit? How would that physically adapt?

My biggest area of confusion is the wiring. I pulled my harness off and sent it out for modification to standalone, but to keep ALL emissions connections. I know I unplugged a connector from the intake mounted purge solenoid, but do not remember another connector or connectors that would hook up to the canister, the pressure sensor and the fuel level sensor? My wiring diagram shows a C152 that looks like it should do this but there seem to be three connectors needed but C152 sounds like one? Any help with this?

Thanks!

PS- this is not going in my '51, I dropped a 6.0 in there but blocked off the purge solenoid because emissions don't apply.
