I have a '93 Cavi 2.2 that I race on dirt tracks.  It currently has the stock fuel tank (we can run it so long as there is a skid plate underneath).  I need to replace the fuel pump and I am thinking that while I have the tank dropped I may just go ahead and put in a fuel cell.
I have heard some people say it is hard to put in a fuel cell with fuel injection and the return line.  Others have told me no problem.  I have also heard some people say to use an inline fuel pump, while others have said to install a stock fuel pump in the cell.
Anyone replaced their stock tank with a fuel cell?  Should I use stock pump or an inline pump?  Any tricks I need to know if I do it?
 
Ok this is pretty easy.  I went and bought an in line fuel pump from either a Ford Ranger or F-150  Its a simple 2 wire hook up.
I went to NAPA and bought a replacement factory fuel line connector for the ford fuel pump.   then I bought a repair splice kit from Napa as well to splice into my factory fuel line just before the stock  Cavalier fuel filter.  this way I can still run the stock fuel filter.
The return is already there just lengthen it to reach back to the fuel cell, don't forget you need a vent on the fuel cell so don't just use the vent for your return.      Really its that easy!
here is a pic of the splice
