Why have an 18 gallon tank when you can have a 38 gallon one? Let's go!
This is a Spectra F26E tank. Fits right into the frame rail, and comes with longer hardware to reuse the original gas tank straps
I modified the original sending unit to reach another 6" down to the bottom of the new tank, and then replaced the original float arm with a longer one from a bronco sending unit, altho i had to change the shape of it (bend) to get it to display accurately, while also being able to fit it thru the hole in the tank
Sorry i dont have better pics as this is when i broke the lens over my camera, so youll have to wait for the video if you want more info on the sending unit mods.
That said, the tank is installed!
As you can see, it fits in there nicely and despite being bigger than the bronco tank, doesnt hang down as far:
This would be the end of the mods for the swap, except dump bed. Seems theres some aluminum in the way:
I had to notch the aluminum frame rail to make room for the filler neck. I also removed the coupling and extension hose to shorten up the filler neck a few inches, and then built a hangar to support the neck:
...and the finished product!
