People are going to tell you to run a walbro or a second factory pump, but I would also like to know the answer to the same question. i wanna run 250/100 but i would think you would run the same pump

I would suggest either the 150 or the 165. I would personally go for the 165. Leaves room for additional power down the road.

I don't have any fueling issues that I know of. I have the Air dog 150 with a RR from Dennis and Full Force 238's. I have to back off on egt's before I would know if I run out of fuel.

Why are you running a airdog 150 and a walbro fuel pump

What's the point of deleting the factory fuel bowl, I've heard of allot of people doing it but I've never seen why.

I have the walbro as well. The airdog 150 only adds like 7psi fuel pressure. It is basically for removing air and another water seperator.

Clears up valley, better filtration with different filters, less fuel leaks, etc..

That sounds like alot of money to spend for 7psi and another water seperator

Agreed, but its also a lift pump so it makes life easier for the other pump. So longer life for the supply pump since it doesnt have to pull the fuel, it just pushes it.

In my case, the factory fuel filter is removed and I needed a water seperator, also added a sump and wanted a better pre fuel filter..Then lets talk about removing air out of the fuel system,
after watching the airdog150 in operation, i feel that the injectors are seeing pure fuel, or at least as close as it gets.

factory fuelbowl will support 600 hp.

i have no plans to remove mine unless a big oil system requires it.

I like the fuel bowl delete because it frees up space, eliminates possible leak areas and you can get better filtration. I wouldn't have a stock fuel bowl on a stock truck.

If you add another filter to replace the fuel bowl that is 3 micron or so....
Injectors are far costlier to replace then a cheap filter.
Ford's system works has filters everywhere and even has a heater.
The brings can leak and some people manage to track them but to me I see zero rest. To replace it u unless it fails.
