fuel pump and tank for fuel injection

[dmoss69]

What's the cheapest tank or pump set-up that I can find for putting a in-tank fuel pump setup under my 85 shortbed?

What I have:
1985 chevy shortbed
It has dual tanks
I'm taking one tank out, if not both, and replacing them with a tank that I can put the high performance fuel pump in.
I have a high performance pump now, 340lph, so all i need is the sending unit piece to adapt, or if there is a cheaper tank alternative to try.

I didn't see anything as of yet, I'll go search some more!

Thanks
