Relocating gas tank using one from an '87?

[botboy]

Wondering if anybody has done this sort of swap. I have an '87 I'm parting out (Check this thread if you want some parts: http://67-72chevytrucks.com/vboard/s...threadid=85178). Anyways, I was thinking about how much I dislike having the tank in the cab with me in my '72 C10, and how much I'd rather fill the drafty fuel line holes and put a pair of nice speakers behind the seats.

So, I have a pair of free tanks from a '87 2WD.
I'm sure some people on this board have moved the tank outside of the cab.
Where did you put the tanks on the frame? How did you hold them there? What kind of tanks did you use? Pictures please?

I haven't pulled the tanks yet from the donor truck, would that year have fuel pumps inside the tank or between the tanks and switch/engine? I know that the '87 doesn't have a fuel pump thats actually on the engine.

Would it be wise to install a fuel pressure regulator (I'm still running a carb) and use the pump that is inside the tank (assuming that it is inside the tank not on the frame?) Or to route around the fuel pump and use the pump that is already on the engine in my '72?

thanks for the help.
