I need to replace my injection pump soon. I have 91 7.3 idi non turbo. What pump would you recommend for fuel economy and what would you recommend for power? btw the truck is all stock.

 

you can go with a moose pump and BB coded injectors .... that's the best set up for these engines... also you will nee to make sure the (IP) will need to be timed appropriately ... this will ensure good power and economy .....

also put a large air cleaner and a free flowing exhaust on it if it doesn't already have one ... My suggestion is a min of 4" dia. exhaust post of the y... with 2.5" primary's off the manifolds..( they do make headers from what I hear but not really needed)..
