Gas tank replacement
I did some searching here on the forum, but can't seem to find anything. Is there anyone out there who makes replacement in cab gas tanks? Poly would be preferred, but I'd take metal too.
The tank in the cab of my hiboy is rusty and full of god knows what, and I don't think cleaning it will be a viable option. I'd like to keep one in there, because the aftermarket side tank I've got will leak out the fill neck on inclines.
If I can't find a tank, I'll attempt to clean my own. My only concern is that because there is so much crap in the tank, I won't be able to get everything out. I've thought about getting the tank boiled, but then I'd be worried about compromising the structural integrity of the tank. Not good to have a weak tank when it's right behind you driving down the road.

Any help is appreciated!

Not a 100% sure, but I think Dennis Carpenter and Blue Oval Truck Parts have new in-cab tanks.
If all else fails, Eastwood has a system that you can buy. It includes stuff to chemically clean the tank, then a coating that you slosh around inside to seal anything that didn't get removed and it also seals small pin holes.

Just checked, Blue Oval has them for $209.95 they have both without and with evap emission controls.
They are steel. I don't know of anyone making a poly in-cab tank.

I wasn't fond of the idea of a gas tank right behind me, mainly due to the smell and of course the safety factor. Have you considered replacing the rear tank with an aftermarket? That's we we did, and the new tank sits inside the frame rails under the bed. We then put an electric fuel pump in because I got tired of having leaky diaphragms at the most inopportune times...
We removed the in cab tank entirely.

My brother had the same problem on a '66 he bought. We took a mini-grinder to the seam around the edge of the tank and essentially just split it in half (like opening a clam). Cleaned all the rust and crap out of the inside, put it back together and bronze-wlded the seam.

I'd recommend removing the in cab tank. Here's a link why (it's about chebbies, but I think it applies to the fords of the same era as well).

I agree, and recommended the same thing to my brother, but he went the route I described. And just to add to what Dutchman says, along with that electric pump use the relay that runs off the oil pressure sender so you don't get fuel pumping when the engine's not running.

Unfortunately, the replacement tanks (that I could find anyway) fit only behind the rear axle. I'd much rather have it out of the "crumple zone" (do these exist in the old trucks?) ahead of the axle, but still inside the frame.
And yes, Coyote - definitely have the inertia/shut off on the electric pump set up.

As far as the "crumple zone", you have to figure that if gas tanks in trucks and cars can still be found behind the rear axle/suspension, that there isn't very many cases of the tank exploding or catching fire in a crash. Since most collisions are head-on or side on, behind the rear axle inside the frame is probably the safest area for a tank.
I do have an aftermarket tank on the truck anyways, one that fits between the frame and body like the chevy saddle tanks (which in fact, the exploding tank was written off as an over-exaggeration). It's a poly tank, and I've been running the truck of that for a while. The problem there is the fuel neck leaks on inclines.

Long story short, I pulled the tank out and was all prepped to be cleaning out some nasty rust (I even had acid to clean it with), and I pull the fuel sender out and stick a flashlight in, and lo and behold there was not a single spot of rust or gunk.
So I just cleaned it out with some hot water then prettied up the outside. Blew out all the lines with air. Not sure where all the **** was coming from, but it appears to be gone.
