Fuel Cell Help

I'm starting to build a fuel cell out of steel and have a few questions.  It's for a Dodge Ram and I'm planning on using the stock sending unit.  What does everyone use for a tank sealer?  I saw that Eastwood has a decent kit and was wondering if anyone has used this?  Also wondering if I need to put baffles in the tank?  If anyone has any other tips please share! 
 
Thanks for your help!

i would put a coulple of baffles around the pump area. ive used por 15's kit, it works great.

I'll have to check the stuff out. Thanks James.

Had mine made, stainless no sealer/no rust,used stock pump & sender plates & stock pump baffle!Also use the stock filler neck so to pass smog!
