I have a new Stage-1 Fuel pump free if you pay shipping. It’s a weird one though. It’s made in USA by Carter. I bought it sight unseen over 10 years ago and thus is what I got. The arm has a different bend but length ends up the same. The bowl actually looks a bit bigger than the stock AC unit. All connections are in the same orientation. It’s not doing anyone any good sitting on my shelf. It also has the riveted on cam pad that I don’t think newer units have anymore.
