Yeah I saw him mention the EP381 pump so I was assuming he used the stock TBI hanger/sending unit as well which had me curious about the EVAP stuff. I was planning on swapping in a newer sending unit like you mentioned since it's all self contained but besides having to modify the tank to fit the newer style sending unit (check out vette works for the adapter flange if you haven't already) you also have to modify the height of the newer assembly (NastyBuzzard showed why and how to do that part in his build thread a while back) and I wasn't sure how that would affect the fuel reading with the float not going through it's full range since that also affects how the ECM tells when to vent the purge solenoid, at least as I understand it... To be fair that might not have caused a problem at all but I didn't want to go through the trouble of making everything fit only to find out there's a problem and have to drop the tank again and figure something else out.
