Veering off topic, but I noticed (in our cool climate, on a 454)) that the TBI gets INCREDIBLY hot, although this is with an aluminum intake. It was hot enough a few minutes after shut down to vaporize fuel that dripped onto the TBI to intake bolts. I was very surprised that they got that hot. Maybe circulating fuel 20 seconds is enough to take enough heat out of the aluminum. Even after sitting for a day, the TBI still had fuel pressure in it when I went to take the regulator back off, so I assume it makes some difference.

When he didn't have the module hooked up he didn't notice problems, but again, this isn't in a very hot climate either.

Substituted a nut for the thin shim I had already tried in the FPR, BLM's better get driven down this time. :)
