Bosch 044 In-Tank Filter Information
Since there are a good number of people running the Bosch 044 in-tank, and a good number interested in doing so. One of the problems people run into is:
What to do about the in-tank filter or sock?
There are a couple of "over-the-counter" options such as:
Bosch Fuel Pump Pre-filter Fuel Sock For 044 [BFP-PF1] - $35.00 : Jay Racing
Ultimate-Racing*::*Universal Parts*::*Pre-Filter Fuel Sock for Bosch 044 Fuel Pump
https://www.pegasusautoracing.com/pr...asp?RecID=5812 (Need to order both of these)
https://www.pegasusautoracing.com/pr...asp?RecID=5813 (Needs the part above as well)
There is also the ability to build your own (essentially the equivalent of the Jays Racing) using a number of different components that can be mixed and matched.
First, you'll need an inlet adapter. Something that will go from M18x1.5 to 22mm OD.
Adapters:
Part #1HDW52 (Various MFG's)
This one is pretty common, it's sold by Pegasus and a few other companies. Only problem is it is quite pricey.
Sytec Adapter (Part #ASA06)
This can be difficult to source, as it appears to only be found in the UK region. Typically they can be hand for around $10EUR. This is the same fitting that the Jays Racing designs use. They can be found on eBay or a number of international supplier sites.
-10AN to M18x1.5 (Part #9919FFKERL, FRA-461018)
NOTE: This appears to be the way the new Jay's filters are being constructed. There are pictures over on the Supra Forums about this setup. Essentially, they're using a -10AN (7/8" threads = 0.875") since it is close enough to 22mm (0.866"). They're then cutting the fitting down to size and epoxying or gluing the fitting to the filter. You can see the necessary modifications in this picture:
Filters:
MST Part #22-018 (30-60 Micron)
This is typically found overseas as well, around $5EUR.
Walbro Part #125-135B (31 Micron)
These are extremely easy to find, as they're used on a few Walbro pumps. Typically should be around $5-6USD. They are the same filters used by Pegasus and a number of other of the "over the counter" filter setups. Hope this helps!

I am doing something a little different as I am using E85 exclusively. I have fit a Fuel Labs Stainless Steel filter sock onto a in tank Bosch 044 which I am using as a lift pump. I simply cut the -10 AN threads of the supplied fitting, cut the Jays racing adapter to the threads and welded them together. Works great.

Jay Racing: Currently, they are not using the Sytec or a modified AN adapter. I've bought two filter sock setups from them over the past three months, and their adapter is different. The height of the smooth cylindrical part is much shorter, and there are no internal NPT threads. Also, the filter sock isn't glued; there are metal tabs that grip the adapter piece (like the Walbro image). If you do use the Sytec adapter, be sure to drill the holes as shown in your image so it won't seal off all fuel flow when it slides all the way to the bottom of the filter sock.
The info you have on this is probably very old; I believe Jay Racing changed their design at some point. The current version looks very robust -- although the adapter doesn't have castellations like the top image, the sock has internal plastic ribs that would prevent it from collapsing and causing the flow problems associated with early designs.
MST: Looks like a reasonable alternative, but it's much taller than the sock style filters, which could be an issue, depending on your installation.

Guys,
if you are looking for the 044 in-tank, please search for the 005 which is the 044 but made by Bosch for in-tank use. The 005 was also used on Ferrari 512, so you can use it as reference for your search on the net.

Glad you started this thread. I've done a little research into this, and here's what I've found:

You are absolutely correct on modifying the Sytec fitting. I usually mimic this design when I mod my fitting:
I'm not sure I would want to use the 005 this way. The 005 essentially is an 044 with a built in pickup screen in the bottom of the can. While this screen would probably work as a "filter", it's built into the unit so replacement isn't going to be easy. Also, all of the stock applications have this unit sealed in a plastic carrier with an additional "sock" style filter before it ever sees the 005 screen. The 044 is also much more common and easier to find.

The open bottom would allow the elimination of the sock filter. But for steel fuel tanks, I like the extra surface area of a sock filter. It gives added ability to survive flaking rust (in case your car has some of that).
BTW -- the -044 has an internal filter that's similar to the ones used on the "open bottom" filters like the -005. If you look in the inlet, you can see it.

Good to know. The last Jays filter I bought was about 7 months ago and had the Red AN fitting similar to the picture I posted. I bought one with the Sytec about 1.25 years or so ago. Is the new fitting still the same 22mm OD? Did they change filters or is it still the Walbro filter? The Walbro I have here has some plastic skeleton in it, albeit not much, but with the correct fitting it isn't a problem.
Also, all of the stock applications have this unit sealed in a plastic carrier with an additional "sock" style filter before it ever sees the 005 screen. The 044 is also much more common and easier to find.

I agree that another filter is a good idea in front of the "internal screen" on the Bosch pumps.

Good information! I am curious though, what Jays fitting did you have? The Sytec blue fitting or the Red AN fittings? From the spec sheet, you can see the filter element is designed nearly in the same manner as those I listed previously. It uses a 0.875" (7/8") inlet. That filter should fit the Sytec adapter without modification, or even the M18x1.5 to -10AN with some slight work. Hopefully I can find something more readily available than the Sytec's to accomplish the same task.
Thanks for the information!
Here's the dimensions of that filter:

Seems there have been a number of revisions then. Overall, the basic concept seems to be to find something that'll go from M18x1.5 to 22mm, preferably of a short overall length, or with modified inlets such as the two fittings suggested earlier to prevent the inlet closing. Good stuff though, the more information the better.

I'm not generally a fan of plastic parts when there's a metal alternative . . . but I am a fan of OEM parts when they will do the job due to their proven reliability. In this case, I like the Walbro style filter because they're used in numerous OEM applications with many years of good reliability.

If the pickup pump is running a pre-filter, then there should be no need to prefilter the swirl tank. Unless the lines, tank, or pump itself degrades it should be just fine.

My Own Filter Sock
Since there wasn't an aftermarket filter sock that did everything I wanted, I designed my own. It has a few key advantages:
1. The filter strainer is an OEM piece, with OEM validation and reliability
2. It's retained to the adapter with 6 stainless tangs -- very strong
3. There's a gasket inside the filter strainer that seals it to the adapter (many others have sizeable gaps in that region)
4. I provide the adapter and filter strainer separately, which makes installation easier

Banned. I got OWNED!!!
I'd run a standard AN fitting conversion from the pump inlet and Y-block it to a couple of these ATL "Duck Foot Fuel Trap Pickup w/ Filter" to place at two corners of the fuel tank.
Part #s
-6AN = TF239
-8AN = TF240
-10AN = TF442
2x -6AN would be plenty.
Really though, you should be using an internal surge tank w/ lift pump integrated and that's your swirl pot. Pierburg (tons of options) or Walbro F90000274 will do better at low pressures for a lift pump, then Bosch 044, Pierburg, or Weldon for your pressure pump. If your Bosch 044 makes a sound like this (see video below), then you should regulate the fuel tank to the point of maintaining positive pressure (forcing fuel out and into the pump).
