Golf gti mk2 16v external fuel pump housing

I've discovered today that I have a small leak coming from where the reservoir is seemed.

Now as you will all know this item is now obsolete which leaves me with a dilemma, I've tried loads of breakers who haven't got any in my area, there's none on eBay, my local dealer has checked around and can't find any showing stock even Germany.

So what are the options?

If I run a inline pump and no swirl I will potentially suffer starvation.

The digi unit won't provide enough pressure

I've searched the net but no one as yet has come up with a alternative set up but it will be a issue that will effect us all in future

 

I've seen K-jet GTI's converted to Walbro pumps, you can fab up a bracket and use the stock swirl pot with it.

 

That's the problem my swirl pot is split, and this is the part that's obsolete

 

Don't know if this is just a stupid idea ! I've not had this problem yet could we use a large fuel filter to replace reservoir ?
Seems like a cheap fix if it will work but not had a look at the problem yet.

 

Ah, I misread, I thought your pump housing was split. I guess you could use the swirl pot from any k-jet car (volvo, benz, etc.)?

BTW I looked up the part number for the accumulator:

KR - 431133441C
Bosch direct replacement is available (part no. 0 438 170 027) around 150eur

PL - 853 133 441
Bosch (part no. 0 438 170 042) around 170eur

EDIT:

Also KR accumulator alternative from Seat is available at 265eur. Quite pricey
