OT rant about keeping '77 B200 camper on the road; then a fuel filler question
I built a nice, balanced LA 360 smog motor for my '77 B200 Sportsman Royal camper that I've owned since new. I've taken a few long road trips in it, and it runs pretty much like a new vehicle. I would like to take some more trips, but have trouble getting it smogged.
It has ported "J" heads, match-ported Edelbrock intake, forged pistons and a MP P4452759 (260-268) cam (which is about the biggest one I think will smog), and I kept the C.R. at the stock 8.5:1 so I would be sure to pass, and it did. I like the engine, even though it is a bit of a dog off the line with that low C.R. and all that porting because it runs strong at higher revs. It's got a 727 Loadflite, the 9-1/4" 3.55 rear end and a rebuilt Red Top steering box.
My problem in passing smog is that my original 36-gallon polyethylene tank leaked, failed the evaporative test, couldn't be repaired and is NLA, so I have to switch over to the only kind of tank available that will fit, the 22-gallon steel unit made by Spectra. I was able to get the correct 22-gallon tank straps and sending unit, but I have to modify my old filler tube to make it work, since the original 22-gallon filler tube is also NLA. My question is, I don't understand what kind of filler tube stub is supposed to mate with the tank inlet:
I have never seen one like this before. Could somebody please clue me in as to what kind of inlet tube stub will mate with this tank, and how it is supposed to be sealed? Or maybe a hose connects to it directly? Thanks very much. (I tried asking this question in the Dodge van Facebook group, but got no useful responses, and I am not aware of any other Dodge van forums that still exist. I also asked the eBay seller of the tank, but it is fairly hard to communicate with him.)
