What kind of fuel pump should I get for twin turbo C5Z?

I have around 700rwhp and the UPP setup including their fuel system. Im losing fuel pressure during normal driving from 58 now down to 52-54. I figured its time to replace the stock in tank pump and filter since its from 2001. Any ideas what pump I should get to replace stock one?

Lingenfelter and Racetronix make drop in pumps but you can get creative and fit a 450 in there for more headroom.

I run twin 340's with the racetronix harness and its worked great. I'm well north of your power level. First pump runs all the time, the second one kicks on via a Hobbs switch once boost is seen.

I would think you run a return style reg with that- to which tank does the return run?

No pics but you can find plenty on the web. Some have used the Lonnie's setup while others have simply copied the design with is VERY easy to do. I run an aftermarket regulator with a return line. I ran a new (larger) feed line and used the factory feed hard line as the new return as its also larger than the normal factory return.
