It looks like Steve van gent went with the '87+ pump module with EP381 route, so I'm not sure how he hooked up the EVAP to that system.

We are going to actually use the entire '03 Yukon fuel pump module and sender and modify a fresh tank to accept the wider module. So some fab work on the tank with the tradeoff of having a complete factory fuel and evap setup.
