Hi everyone I am looking for some information on what everyone uses for a lift pump if they are using one, I have my common rail QSB 4.5 with a 148 horse tune installed and was not using a lift pump and letting the cp3 gear pump pull fuelwith 3/8 fuel line coming from the tank. When running it this way I couldn’t get the throttle above 1400 rpm before it would start stumbling and smoking white, I installed a lift pump I had laying around in-line and can get the throttle to 1800 rpm before it starts stumbling and smoking white. I have put new fuel filters on and it didn’t change anything. I am looking for a recommendation on a lift pump to make it to 2300 rpm. Thanks for any recommendations
