IIRC, the issue seemed to only affect Zenki and not koukis from the last time I broached this topic.
Have fun with this one, guys.

I’ve seen the theory, but like FaLKon240 below, I have known kouki people it affected too - so I don’t think the theory of it being a Zenki issue only is completely true. There is another theory that the crack is caused by bad subframe bushings causing the subframe to bounce / put pressure on the tank. Maybe there is some validity to that? Would be interesting to see if someone with solid or poly bushings experienced the problem after replacing the bushings.
The real issue IMO is that Nissan used plastic. It was stupid.

Fuel cells are not cheap (at least for safer and reputable ones), not super easy to hook up, and simply unsafe for a Daily or a street cruiser. A rear end collision could be disastrous, You def have to fabricate a firewall and cage/ tube the trunk area to guarantee the safest fitting. You also lose trunk space, lose capacity in many cases, and lose simple stuff like fuel gauge readings.

Nissan today cares very little (re: not at all) about us. I can’t see that happening

To answer both of you - I once floated this on a local board a few years back. I thought it would be simple, doesn’t sound hard right? A dude that I know has extensive knowledge of fabrication and meta engineering chimed in and apparently it’s actually a seriously difficult process and would be insanely costly. I don’t remember the reasons, but gas tanks are apparently much more complex than one initially thinks. I thought of a go fund me up until his super detailed response, and I realized it was incredibly unlikely it would ever happen.

Definitely a positive aspect. I just feel like there are several negatives as well, and not sure it justifies it fully.

A good fix (when it works), but definitely a band-aid. Still thinking cell is the best “permanent” route, but ugh. I really am thinking about doing the pesky subframe pull just to get mine coated in rhino shield while it is still mint, and see if that ends up making a difference in the long run.
