Fuel Tank Filler Pipe Quality

[e21pilot]

I failed the smog test last year because of the common fuel tank filler pipe rotting out on my 92 Ranger. At twenty+ years old, I figured I would just replace the filler pipe with and OE one and get another 20 years out of it.

Unfortunately I had to pull the bed off the truck for an unrelated issue and was very surprised to see that the rubber at the bottom of the year old filler pipe was starting to stress crack already. I looked bad enough that I wondered if it would hold up long enough to get me through another smog test or not.

It could be just a random defect in the part I got or the fact that the alcohol in the fuel is compromising the rubber that Ford is using which probably was not designed for alcohol in the first place.

The question is, there are aftermarket fuel filler pipes out there. Wondering if anyone has had success with any of them for more than a few years and where the fuel they are using is ~10% of the overall makeup.

I R&R'd with one from autozone and it seems to hoding up just fine. I also did the fuel pump from them while I was at it. I can now fill up and not have anything leaking from the tank. Its been about 2 years now, just passed its emmissions BTW.

It's not the ethanol in the gas.

From your previous thread about filler hoses

A word of advice about the new hose:
The aftermarket hoses seem prone to cracking especially quickly (one of mine lasted 1.5 years before I found it looking just like the factory hose did).
Take some high-quality electrical tape (Scotch Super-88, etc.) and thoroughly wrap the outer hose with it (remove the hose clamps so you can wrap under them too, as that's where it tends to crack first). This will prevent ozone and other air pollutants from dry-rotting the rubber and causing it to crack again right away.

Ford hasn't made them for some time now, so whatever one you got was likely an aftermarket one. They're all pretty much the same from what I've seen.
