This is something I plan on doing my self in the future. Well I went looking for the thread on pirate and apparently its gone. But I know Jordan7118 used 1 on his project Snoopy http://board.marlincrawler.com/index.php?topic=40053.0;highlight=project+snoopy
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!
