Fuel Tank Questions

[C10Slim]

So I am thinking about buying one of the CPP aluminum bed mount tank kits. Comes with sending unit and all of that.

Have some questions:

• Whats the difference in a 30 and 90ohm sending unit? Which do I need?
• Do you just run the fuel line off the nipple on the sending unit?
• This tank has 2 an type fitting near the bottom of the tank do I use those instead?
• Mechanical pump or do I need an electric?
• What are you guys using for fuel line? Hard lines? Braided hose?

Basically looking for someone to help me design a fuel system that will feed a 383 SB.

Answers/Thoughts/Ideas?

Thanks!
