In tank fuel pump?

[Jase]

OK so I'm putting a 4.3 Chevy in my toy and installed the Chevy in tank pump in the toy tank.  I used the toy bracket and spliced into the toy wires in the tank. I soldered and used heat shrink at the soldered joints.  But now I'm wondering (for safety reasons) If I should just run and external pump. I'm a bit nervous about    in a fuel tank    .  Any thought or suggestions would be great.
