The small diameter line on your sending unit goes to the charcoal canister. I recommend reinstalling one if you took it out. Every vehicle I have taken one out of I have put one back in because of the ever-present fuel odor that can not be gotten rid of. A buddy of mine did the same thing. Couldn't figure out why his 72 K5 always reeked of fuel. I didn't realize he took it out, so that one took a while to solve. If you decide to add one back in, I have a TBI canister and 72 bracket here that came off of mine when it had the big block in it. It has about one mile on it.

If possible, on your MAP sensor, do not tee it. It *should* work, but I have dealt with strange MAP issues on one that was tee'd. If there is no other way, then so be it, but if you can use one port dedicated, it would be preferred.
