There are actually 2 previous attempts at Dune. The 1984 version, it was the 80's nuff said. Then the 2000 version that even went on to a sequel in 02 w/ Children of Dune which kind of mashed the second, Dune Messiah, and third book, Children of Dune, together. I always figured it was to avoid the religious implications of the title. The 84 movie is hokey no doubt, but name 5 movies from that decade that weren't. The latter flicks, which were actually made for TV, are a considerable improvement. Haven't seen the latest version yet so couldn't make a comparison. Come to think of it, I still haven't watched the Dark Tower movie yet either. Now that was a helluva series, but in true King form, he's gotta twist the knife with the ending. When you get to the author's note at end of the last book and he says you should stop reading, heed the warning.

The idea that FRx or RR is necessary to improve longevity, reliability or ANYTHING else is extremely flawed.

Of course, a lot of folks still think the factory fuel lines ‘suck air’ too.

I agree with Y2KW57 except I like moving the non-serviceable filters in the tank to the frame.

Did this to (2) trucks yesterday. One has 94k miles and the other 220k miles. These trucks fall into the <20% I find with the pickup foot intact....

No FRX. No ITP. No HPX. No XYZ. No LL. No HH. No RR. No BS.
Didn’t your truck come from the factory with a ‘SSJ-style in-tank mod’ situation? (No mixing chamber/filters) Except I get rid of the failure-inevitable umbrella.

No. When I dropped my aft axle tank, the sending unit assembly had the cylindrical screens.

I have photos, but they are on a 20 year old computer that was taken out of service 10 years ago.

Thinking about the first sentence of this response, it occurred to me that a reader may ask in silence "Well why did you drop the tank if you haven't had any problems with the stock fuel system?"

That is a fair question.

The answer, however, is ridiculous:

I dropped the fuel tank to install a receiver hitch.

In a baffling design oversight, that took the powers that be at Ford way too many years to correct (finally, by 2020, chassis cab frames now come pre punched for receiver hitch installation, and the aft axle fuel tank shield no longer interferes with aftermarket receiver hitch designs which have triangular gusseted mounting tabs), the earliest chassis cabs presented unnecessary impediments to installing the heaviest duty receiver hitches directly to the frame, and unlike pickups, Ford has never offered OEM receiver hitches for narrow frame trucks.

So since I had the fuel tank down, I went ahead and opened it up. This was back when Texas Towncar (a former fleet mechanic whose experiments, write ups, and theories created the forum fueled concept of "regulated return" which was then commercialized and monetized by many of the aftermarket vendors who still sell that system today) was still alive. Texas Towncar and HutchinAugusta communicated regularly (until TT passed away) and the Hutch mod was born soon thereafter.

What I found in my all metal tank was a different problem. A pile of corroded debris under the umbrella. (cue Rihanna song). The tank had not delaminated, but I coated the bottom of the tank with Marine Tex epoxy, which I had previously tested against other commonly available two part epoxies by coating small coupons of sheet metal with each type of epoxy tested, where each coupon had four exposed perimeter edges, and soaking the coupons in a vat of diesel fuel for about 90 days. None of the epoxies tested failed, but in my subjective assessment, Marine Tex performed the most favorably, so that is what I used in the bottom of the fuel tank... under my umbrella (hey hey hey).... which I retained in place.

I had planned to drop the tank in 10 years to inspect again, and that 10 years is now long overdue. The point being, I have not experienced a problem with fueling that motivated me to drop the tank back then, nor that motivates me to drop the tank again.

But when I do, I'll be sure and post photos. And who knows, I might even 'SSJ it while I'm at it.
