Actually I was thinking of the Fernox Gel so the capacity is a non

issue
really.


Cheaper to buy a cheap pump-spray (Hozelok garden sprayer type) and
bog-standard liquid Fernox and use the sprayer to squirt the liguid in
through the filling loop connection point (with suitable adaptation to
sprayer to get it to 15mm or 1/2" BSP)



My patented adaptation to do that is:

- Cut aluminium tube of sprayer lance.

- This fits an 8mm compression fitting.

- Short length of 8mm copper tube for other side of fitting

- 8mm solder female x 15mm male adaptor

- 15mm compression service valve with nut and olive on one side
discarded. A male to male compression coupler would do, but I had a
discarded service valve.

- Connect filling loop braided hose to above

- Pump away. (as it were).

Fernox do a filler kit, Wolseley centre catalogue number 603120. at £44 it
could sound expensive but if you are using cleanser and inhib every 3 years
it cuts down on the hassle. It comes with 2 rad vent adaptors (useless) but
the hose adapts to a filling loop hose quite readily with a 15 mail iron and
a 10mm insert.
