2.5 na in a series III questions

[green 'n stinky]

Hello all. I'm in the process of trying to replace my 2.25 diesel with a 2.5 na diesel. Since my truck was already a diesel, all the right fuel plumbing is there, but I can't figure out how to hook it up. Specifically, I don't know how the plumbing works between the fuel filter, the lift pump and the injection pump. Does anyone have a good diagram of the 2.5's DPS injection pump connections, or know where I can find one? Also, I swapped my thermostat housing from the 2.25 to the 2.5, but do I use the 2.25's thermostat? :confused:
Thanks in advance.

use the thermostat that fits, which will be ...errr I think the 2.25's.

the fuel line goes; tank - lift pump - fuel filter - injection pump (injection pump also has return to filter, the connection near the solenoid) - injectors - spill rail - back to filter - return to tank.

Thanks for the reply. I thought the connection on the pump closest to the solenoid was the inlet, rather than the return. I'm glad I asked!
