Ok, so I put some pressure into it, its leaking through the filler cap and the pricker nob, is this the kit I need for it? http://www.ebay.co.uk/itm/VAPALUX-LAMP-BIALADDIN-LAMP-PRESSURE-LAMP-WASHER-KIT-LARGE-FILLER-CAP-/251781148324 The spring in the NRV is also shot so I'll need a rebuild kit for that too.
Well you could, but this one:- https://fettlebox.co.uk/vapalux-bialaddin-washer-kit-w5-type.html is cheaper with your 10% members discount and better quality into the bargain. You know it makes sense...
