Mercy, there must be a dozen threads on here about return lines on our cars....
and yes, I've found the easiest way to search FBBO is actually to go to the google website and
search from there, as the search box on here is famously wonky as hell.
Easy-peazy! Nice.I think the Wix isn't metered, as opposed to the original 440 type which has the .060" metered orifice. Seems to work well for many though, including a fair number of forum members.
Well, I took the plunge and did it already, and - sure enough - the 150W iron was only hot enough to get the solder onto the surface, but following that up with a small butane torch did the trick. I wound up using a socket as a heat shield and heatsink, and it worked perfectly.

Now, if it's not clear in the photos, I did wind up tilting the tube up, for better or worse. I was going off of some original 440 senders and it appears as if they were designed to dump above the fuel level, so I imitated that. Probably because they were metered.
I went ahead and started soldering before anyone had posted whether to point it down or up, so apologies to those who have suggested otherwise.
However, there's nothing stopping me from flaring the end for a fitting and connecting an inverted J-bend back down with an extension. Come to think of it, it may be the only way to do it and still get the sender to slide into the tank.
Makes sense. Seems to work pretty well for many on the forums though, and there's one or two videos on YouTube praising it. Doesn't necessarily mean it works for all situations, but I don't mind giving it a shot.
FYI, the vapor lock wasn't the primary issue - I'm installing an electric fuel pump at the moment - but I decided to add it into the mix as it'd be an opportune time to drop the tank.
Duly noted - see my reply to 70chall440 about my error in pointing it up.
