Do you really know what that entails and how much it would cost? There is a reason why all three opt to get their pumps from suppliers rather than making the fuel system themselves. In fact, most of the stuff on the engine comes from suppliers.


The same goes for all three. Take the Powerstroke for instance, Ford may make the block and many of the other hard parts in their foundry in Mexico, but the pistons likely comes from Mahle. The ECM probably still comes from Continental. The fuel system comes from Bosch. The turbo has come from different suppliers over the years like Garret or Borg-Warner. Same goes for the Cummins except that Cummins owns its own turbo manufacturer, Holset.

I have no idea what it would cost. Apparently too much for a little company like Cummins. Maybe Ford will have to step up to the plate and show them how it’s done.:)
