When I'm driving at highway speeds and start going up a hill the truck starts to sputter like its not getting enough fuel, the fuel pumps are both new. Any suggestions on why or what's causing my truck to do this.
I am driving a 95 f150 flareside, 5.8L, automatic, 4x4, dual tanks.

 

just wondering but how old is the fuel filter?"

 

when the fuel pump's were changed, the fuel filter was replaced as well

 

It's not likely fuel supply has anything to do with the actual problem since you recently replaced the pumps, pull the codes and describe the overall level of tune of the vehicle. Are there any audible exhaust leaks?

 

the passenger side has a slight exhaust leak at the collector.
