Default Fuel Tank Swap

I have an '03 Sierra with an 8ft bed and 36 gallon fuel tank, can I put in a 26 gallon tank from a Short Bed truck. Will the straps be the same as well as all of the hookups? Anyone do this yet?

Ok, let me ask another question.

Could I have the tank cut open, install a few baffles and re-weld (plastic weld) the tank together? Would that keep the fuel from running to the back of the tank and starving the motor on launch? Of course I would upgrade the Pump to a Walbro, 255 or 400.

Yes you can cut an pastic weld it back together. I have done a few like that but you can install a fuel cell to the back just as easily with better results.

Installing a fuel cell in the back means I cant use the factory fill door. It also means cutting into the truck bed for a new fill door. Can't put gas in it either when I got a load of gravel or wood or car parts thru the door in the bed.
What do I do with the spare tire back there? For me and my application, a rear mounted tank is out of the question.
I need to find a place that does plastic tank welding in the Dallas / Ft.Worth area or somewhere in Texas.
Thanks for the input though!
