Double Pumper vs. Dual feed.
Right. DP usually has nothing to do with dual feed. Some carbs can be converted by swapping fuel bowls
This is a spread bore, in DP, and they also come with vacuum secondaries. I don't believe either come in dual feed in any configuration
If the carb is a square rather than spreadbore, I believe those all come dual feed if they are a DP. I guess you could put the small bowls (two primary bowls) on a square bore DP and convert it to single feed, but I don't know why you'd want to.
Vacuum seconary, square bore carbs come either single or dual feed.
