Re: Blazer tank swap into K10
It's good to see some interest in this idea. I decided that I would either get a new tank, or clean and seal my old one prior to firing up my new motor. I dropped the one saddlebag that I have, looked at it and said, "that thing isn't going back in the truck." So I ordered the blazer tank, new for 97 bucks. I figure I can get it work, one way or another.
I looked in front of the rear axle as well. After looking at it, I thought that behind would make a little more sense as the blazer tank is about 11 inches top to bottom, and 14 if you include the filler neck. Besides that, if you were to break a u joint, your driveshaft could hammer the snot out of it, and the front could come pretty close to interfering with the tailshaft of your t-case. With a 3 inch body lift, you might have better chances.
I also thought about the in bed option, but my choice for a tank in there would be more like an L shaped tank that you could use for diesel fuel or a custom one that you could mount below a toolbox or something. i just would rather have the majority of the bed free of obstructions, and a filler neck that won't chance contamination. For a bobbed bed, it might work out well.
Hopefully, I'll get my 383 fired up this weekend, then I'll think about lifting the bed off. For now, I've got a little 6 gallon boat tank in the cab. Before anyone goes OSHA on me, I'm not going to run it around this way. Just a temporary tank to move my truck around to my garage and back and get my engine fired up.
