I'm using a simple inline fuel pump. It flows 50gph at 70psi. I believe it was $189 and will support 450rwhp no problem.

I agree, getting an inline pump will help out fueling to a certain point. I'll probably install a Walbro GSL392 pump just after my fuel filter to keep pressure from falling. Doing an inline pump is not as good as an in-tank upgrade because the tank pump is still in the series and can become a restriction. Its cheaper do buy the tank pump since it doesn't need the external case and fittings, but its more difficult since you have to pull off the tank.

Your other option is to run a small fuel cell in the engine bay with an external pump to fuel your nitrous. You can keep it full of race gas and it will only be used when you spray. Obviously, this is the more expensive route.

Yea I was wondering who makes a in-tank pump for our trucks. I havent really found any. I have seen upgraded fuel pumps for f-bodys but not for our trucks.
Does someone have a link ?
