I'm looking at fuel tank options at this point. While I understand that custom tanks are all the rage, I've seen a thread that covers a 40 gallon tank from a square body suburban.

In looking at rock auto, they offer the tank for under $200. That, and the 3-outlet fuel sending unit (another $70). The question is (and now that I can't look at the trucks) will this set-up work for the cummins? The P7100 is the pump, so I wouldn't need anything other than an in-line fuel filter, correct?

I actually mocked up a burb tank from an 89 V20 and it fits pretty nicely. What power level would you like to be at later on? On mine I'm going to see if the sending units operate in the same Ohm range. I'm not sure if they're the same from 72 to 89. Either way, I'm ditching the stock suction tube for a draw straw 1/2" diameter. In the past I've simply removed the stock suction tube from sending units, drilled the hole bigger in the sending unit, and brazed a 3/8" line I bent up in the sending unit. You can run 3/8" feed and 5/16" line on your truck and use the factory lift pump on the LH side of the engine block. No filter is needed pre lift pump. There is a screen to filter large debris in the lift pump inlet. You can add one pre lift pump, but you'll want to make sure it can flow what the stock lift pump will flow to not over heat the lift pump. This is another nice feature of an aftermarket fuel system. But, to keep costs down, you could get a filter head and run a good water seperator pre lift pump and be good to go.
