OK, we get air in our fuel system because we suck fuel from the tank. There are fittings that leak, and the mixing chamber that.....well, leaks.
So, we put in solid lines and hoses with worm clamps to prevent this.
Secondly, many people espouse the great virtues of the Bosch 044 pump as a remedy for a failed/weak stocker. This pump would also suck fuel like the stocker.
Therefore, I submit, as written in Bosch literature, that the 044 be used as an in tank fuel pump. Submerged in fuel, cooled and lubricated and no inlet leaks.
It should be easy enough to cobble a few fittings together, add the Bosch inlet filter (sock) and make the whole fuel system one of positive pressure.
The only negative I see, is if the pump should ever fail, one would need to drop the fuel tank again.
But a Bosch should easily out live any stocker, so I can only believe that the pump would likely never have to be removed again.

OK, so where did I jump the track?

The stocker IS a Bosch pump of the same style as the 044, just a lower capacity. You would still need to put a bunch of new lines in the truck to run the 044 intank. So if you have to put new lines on anyway might as well have the pump on the frame where it is easy to change should it ever fail.

Pressure from the tank forward would be nice, but with good plumbing I don't think it is a non-issue.

Sounds like a good idea to me.
1.Will it fit through the opening in the tank?
2.Do they have a sock that mounts right on there without fabrication?
3.Is there room for the pump, AND the sending unit for the gauge to fit at once?
4. Theres still a chance of getting air when the fuel level is low, from sloshing.

I'm asking cause a fuel system is in the works for me right now. Just gotta figure what route to take.
It does sound like a good way to do it to me. Might as well drop the tank anyway to clean it if for no other reason.

Yes, the pump will fit inside the tank. Yes there are several sock options that will thread right into the 044's inlet fitting. With enough fab work just about any pump will fit with the stock sender in the tank. Yes, you could still pull air into the pump when the fuel level is low.

As long lived as these pumps are, I'd tolerate any air that may get pulled in with the pump on frame with good plumbing to have the ease of replacing the pump on the side of the road in BFE. If you really want to run the pump in tank then there is absolutely no issue with it from the pump standpoint, the 044 was designed for either rail or submersible mount.

Here's a thought. If Ford is really all that big on using common parts between models, why not find a fuel (gas) tank from a V10 gasser. If you find the tank from the same body/chassis combo (reg cab, super cab, crew/long bed short bed) it should fit our Powerstroke trucks too. That will have an in tank pump and all the necessary fitting for supply and return. Just switch out the pump with a diesel compatible (Bosch) pump, run some hoses and bingo! Or just use the whole pump/sender assembly with the new pump.
Right?!

I know it's been done before (putting the pump in the tank), at least with a stock pump, and he's having good results with it. I'd link it, but I don't know if I can link to a different forum.

My fuel pump luck sucks! Hell if I'm putting it in the tank LOL.

I will have a bosch on the frame rail pumping like 8yr old kid with a flat tire bicycle though soon

I do not think the 044 was designed to be used in your tank. Bosch does make several pumps designed to go in your tank complete with appropriate fittings. The 023 is an example rated at 165L/min. The difference in design is that the entire inlet side of the pump is open with a big screen rather than sipping through a long skinny straw. It is designed to sit near the bottom of the tank. I will post additional links with pics later.

On edit: Compare these images of an 040 intank pump with the 044 in line pump. 040 pics The 023 is the highest flow pump designed by Bosch to be intank ie. open bottom. It only flows 165L/hour at 72 psi or about 43 gallons per hour compared to the stock pumps output of about 30 gallons/hour at 72 psi. I think that is still a significant improvement over stock and if you can keep it immersed, it would decrease some of the air in fuel problems.

If the Bosch literature says the 044 can be used in the tank, I don't see the problem with putting it in the tank. Even in the item description, HERE, it says it may be installed in the fuel tank. Also, HERE is a 30 micron fuel sock designed specifically to allow the 044 pump to be mounted in the tank.

I would like to see the Bosch literature if anybody has a link to it. I think some folks might consider using the 040 pump as a lift pump for the 044 in line pump if they needed more than 58 gallons per hour at 72 psi. I am not sure anybody sucks that kind of fuel down though.

I have been thinking about an Airdog. This is interesting.
