fuel cell help

I am thinking about putting a fuel cell in my truck for when I BD it. I was wonder what everyone with a fuel cell were using. Meaning did you have one made to accommadate your stock fuel pump or did you use an electric fuel pump. which would be better to use. Thanks for all the inequires.

Had tank made of stainless useing stock flanges ( Ca. a fuel cell won't pass smog)!

I just built a few for a couple of people and one was for a 00-05 silverado for the stock location and it retains the stock fuel sender.
