Lift Pump
While a lift pump would almost certainly work around the problem, would it actually SOLVE the problem of an apparent leak in the fuel system? Or would one begin to see fuel coming from said leak, thus making it easier to repair and end up being ahead of the game in having a lift pump ease the stress on the HPFP?

Every Dmax should have a lift pump. By not putting a lift pump on you are doing the fuel system a great disservice in letting the system process excessive amounts of air. Placing the system under pressure will almost certainly cure the issue at hand, AND if there is a leak of sufficient size it will show itself. In most cases there is not sufficient leakage to even weep fuel. It simply lets air in and can be one heck of a time and money waster trying to track down.

Of course you could go see the dealer and be told that the fuel filter housing is "cracked" :rolleyes: and needs to be replaced... $$$
I had same problem and low and behold it was that little bleeder screw on the fuel filter housing. for some reason its made of plastic and it was striped and letting in air. i ordered an aluminum one from MA, fixed it.
The plastic bleeder screws while cheap really are not that bad. The problem is when guys use tools on them. If you only finger tighten them they'll last forever and they seal well before they seat.
For this reason we made our aluminum bleeder as a thumb know with a knurled/striped outer rim that stands much taller than the OE nut flange. I did add a nice deep screw slot for good measures. I also anodized it red for easy location for newbies. You never know when your truck will be out on loan and you have to talk someone through a basic prime operation.
I still say that a lift pump is necessary though...
