That's me!!!
I used the stock rear tank from an early 90s F-150. I used the Ford pump and sender, and wired into the stock Toyota wiring. I love it! It's awesome. I humped some rocks with my frame that would've DESTROYED the stock saddle bag tank. I'd recommend this tank, especially in a truck. I put it up as high as I could without cutting into the floor. There's more pics in my buildup. Let me know if you have questions!
What fuel pump worked? Is yours EFI? I really want to do this. Any info would be appeciated. THANKS
