I have been looking at the Walbro FRB-5 electric pump.
45gph at 8-11psi. You won't need a regulator and will supply plenty of fuel.

I'm using an FRB-22 as the backup pump on a 3rd gen. Bascially same pump, marine version, better corrosion resistance.

Your local Cummins or Case dealer should have it in stock, or be able to order one.

With 370's and pump tweaks, I'd say you will probably need it. Even if you don't, the piston style lift pumps are a whole lot better than out diaphram lift pump. In my opinion of course.

I noticed a decent improvement in top end power when I installed a piston pump and I'm still running stock sticks. It's hard to tell if you really need it without a fuel pressure gauge, but I would bet that if your running bigger injectors and some fuel screw, you need it. I think it's an upgrade that is very well worth the money. :D

Lift pump was the first real weakness I found after I 1st got my truck about three years ago. Put in the 32k GSK and just turning the fuel cone and a couple turns on the fuel screw would pull fuel pressure down close to nothing at WOT. After installing the piston pump it fueled hard all the way past 3k rpm. Big difference.
