[QUOTE="Tiha, post: 1559302, member: 33189"] So here is a question I have not been able to find any kind of answer for. Fuel pressure/supply VS MPG. I am on a mechanical OEM pump. It works. I really have no issues and no real need to go away from it. Running 180/0 injectors for years and always seems to do "OK" Of course I do not have a fuel pressure gauge in the cab because I don't want to know. LOL BUT here is what I am wondering. In my Gas engines, a weak fuel pump creates worse MPG. Does that hold true for the 7.3 as well? Running a dual tank EFI truck with a 5.8 you would often see 12mpg on one tank and 14mpg on the other. 12 mpg tank (front or rear) needed a new fuel pump and problem solved. However the Gas engine is cruising at a much higher rpm and most likely requiring more fuel flow vs a diesel eking out torque at low cruising rpms. [/QUOTE]
