As Craig mentioned, we can consider running the OEM sender unit without the internal pleated filter, and instead, run an aftermarket external inline filter on the output side of this OEM sender unit.
EDIT: Using an aftermarket inline fuel filter will allow easy/straightforward replacement at service intervals.
Of course, this is a separate issue from the fuel sender leaking. The top half is still prone to cracking, resulting in fuel puddling on top.

Indy wants $1,800 to fix and I'm taking it to the dealership tonight to see if they will good faith ALL or some of the repairs. FINGERS CROSSED!

Picking up my car tomorrow from the dealer.... (2006 E55 w/~ 47,000 miles)
SA indicated that only the DS was leaking, but then when they went to do the swap, they ended up breaking off the fitting on the PS unit, so that had to be replaced as well. Normally I'd be pissed, but my warranty covered the entire bill on this one ($1100+)
The best news is that since this was a 3rd party warranty, they don't care about getting the old parts back. So I told them to save me all of the parts so I can take them home with me. I fully intend to perform some detailed "Failure Analysis" on these parts and post up my findings....
FWIW: My fuel leak first appeared back in Sept 2012, when the car only had 36,100 original miles on it. That's FAR too early for a fuel filter to be blamed for the leak.... IMHO. I've been playing the "3/4-Tank Fillup Game" ever since.
My Original Thread is here:

It shouldn't take long to prove/disprove hairline cracking of the white plastic area.... some simple dye or even colored water should reveal where the leaks are actually originating from and I will bet money is NOT from the O-Rings themselves.
In the meantime, I absolutely plan to flood my new replacement parts with a fuel-resistant epoxy to increase the overall strength and thickness of those parts.... even the "newest" design parts are prone to leakage, so new parts don't actually FIX the issue.... they simply reset the clock and give you a couple more years before having to deal with this issue again.

This is the filter I am leaning towards if our line is a ~6an:

Stainless mesh at 40 micro is recommended for my E85 system, washable and perfect for inline duty.

If someone is going to do their filter soon, you should (in the name of science!) take some fuel pressure readings before and after swapping out the filter. The clean filter readings would give us a good baseline to see if any aftermarket fixes are better or worse.

isn't there an aftermarket alternative that could replace all the headaches in the tank? Someone CNC a carrier for some pumps, throw the filter on outside of the tank, and lets be done with all these fuel leaks

BTW, I just picked up a trailer hitch that had a 6" rise, then got a ball with a 1" additional rise so 7" total, lmfao

It's a little more complicated than that since we have a humped tank with a venturi setup from one end to the other. It would require two carriers and some fancy routing... considering this is something probably a dozen or less people would be into, the business case just isn't there.

I was there yesterday but all I need to know is our fuel line size. I few people have replied via text, but I have three different answers
This is the filter I am leaning towards if our line is a ~6an:

How many people have actually replaced their fuel pumps themselves? I see owners often taking the car to the dealership... and I'm confident a dealership is likely to turn down a modification job like that.
To mimic the stock system with the venturi would actually be quite difficult without a lot of R&D, it's not just a fuel pump attached to a stick down there.

It is not hard to replace yourself at all.
You will need the special tool and clamp to reclamp the high pressure line once done.
I did mine in about 30 minutes, both sides.

Id like to sort this filter situation out. Its totally ridiculous that we are in this situation where we have to buy a complete housing. This is the closest I have found to the size of the factory one as measured in imperial by OP. Its a bit out on dimensions and style of filter....
http://www.inlinefilters.co.uk/Filte...und/FFR-C11859
That company reckons they can supply it if we can get the part no of the stock filter which probably is not possible....
I have contacted VDO siemens to see what info i get out of them.... not having much hope though.
Some outfit out there must make something thats close enough to a drop in.
