I cannot get any low side pressure in my fuel system. We dropped the tank and check the pump and it works perfectly. Any ideas?

You didn't by chance look at a Mustang? Camaro's can sense these things.

Need more info, even a Zl1 pump upgrade is not enough, many do at least a voltage booster. I did the Zl1 pump (installing as I type) AND a DSX second pump for the low side. I'm told I should see 70 PSI low side through the gears.

Now if you really mean none at all, I assume you are talking about your scanner is showing zero PSI at the pressure sensor that is located in the back of the engine just before the high side pump. If the intank pump is working ie pumping fuel and has power then sorry there is only a plastic S line from tank to metal fuel line and then a crossover line under the hood (across the intake manifold) to the metal feed line to the HP pump.... that can't break.

So what does "pump works" mean?
