Preferably the assembly further comprises a filter head adapted to be coupled to piping of a piped water system and means for removably securing the first housing end to the filter head. Preferably the housing bottom cover is adapted to be secured to the housing via an interference fit.

A clamping system (1) for mounting a filter housing (10) to a wall structure (20), said clamping system including a filter housing clamping flange (2) arranged on a front side of the filter housing (10), and being adapted to abut a front side (20a) of the wall structure (20); a first locking plate (4, 44) having a longitudinal direction (y), and including a locking plate clamping surface (5, 45) extending along a longitudinal side of the locking plate (4) and being adapted to abut a rear side (20b) of the wall structure (20); a first engagement component (3a, 43a) associated with a filter housing wall (11) on a distance from the filter housing clamping flange (2); and a puller (6), said locking plate being configured to cooperate with the puller (6) via an abutment surface (7) associated with the locking plate (4; 44) and being adapted to engage with a part of the puller (6), and said locking plate (4; 44) further being configured to cooperate with the first engagement component (3a, 43a) via a second engagement component (8a, 48a) arranged in the locking plate, wherein one of said first and second engagement components (3a, 43a; 8a, 48a) is a retainer bracket (12a, 42a), and the other of said first and second engagement components (3a, 43a; 8a, 48a) is a push edge (13a, 46a) comprised in a push opening (14a, 50), said push edge (13a, 46a) being an inclined edge adapted to engage with the retainer bracket, said puller (6) being configured to manipulate the abutment surface (7, 47) so as to move the locking plate (4, 44) in the longitudinal direction thereof, such that the inclined push edge (13a, 46a) of the push opening and the retainer bracket (12a, 42a) interact to push the locking plate (4) in a transverse direction thereof and toward the filter housing clamping flange (2), thus clamping the wall structure (20) between the filter housing clamping flange (2) and the locking plate clamping surface (5, 45).

A base filter for a diesel exhaust fluid (DEF) filter of a header assembly in a fluid reservoir is disclosed may include first and second semi-cylindrical holder portions having a semi-cylindrical walls concluding at abutment surfaces that face and engage when the base filter is assembled. The semi-cylindrical holder portions have one or more mounting tabs extending inward from inner surfaces of the semi-cylindrical walls. The header assembly may include a header with a cylindrical header boss having mounting recess defined therein. The mounting tabs may be circumferentially spaced about the semi-cylindrical walls to align with and be inserted into the mounting recesses of the header boss the base filter is assembled on the cylindrical header boss.
