Okay I installed a new fuel pump recently, and now my tank is not venting through the EVAP and building up pressure. When I take the gas cap off, a tremendous amount of air is released from the tank.
The EVAP valve on the intake is working, and the air-line from the EVAP valve back to the EVAP canister is not clogged. EVAP canister seems fine too.
Are these rubber hose routings correct? Where does the RED routing go?
I think in your first picture #2 on the evap canister that you have going to is is supposed to just be open not going to anything (fresh air inlet).
Here's a picture of an LS1 gas tank that someone made the LT1 evap system work with. See, just an inlet for air.
I think your red line (to fuel pressure/vacuum relief vent) goes to the fuel tank vent valve that you have #2 from the canister going to currently, see like this (from a thirdgen):
And I think the "to evap canister" fuel line goes to the UFO valve coming off the canister, you can see it in the first picture. Here's a diagram as well:
I don't know the "right way" for your local emission laws, but a 3/16" hole in the fuel filler cap relieved tank pressure on a chevy pickup with a Walbro 255LPH in tank fuel pump.
