[urq] prepump filter

[Patrick Carlier]

Just found an old one

ID is 9.6 mm ( 3/8 inch give or take )
OD is 12.2 mm (a little less then 1/2 inch )

Then I used a hacksaw and cut in half .
There is a filter inside , so it certainly isn't a sediment only .
And in this particular case , the filter was al clogged and looked
like rusted iron .

I'll try to upload a couple of pictures later on .
