Brilliant, thanks. It is the Zenith 36 IV, and still has an ally tag with number on it. Yeah, I won't be doing anything more extremem than lanes and muddy fields. "Webcon" (unfortunate name for a website, unless it's a double-bluff) have the kit for £155, which seems pretty cheap. My existing choke placement already seems a little weird as it is way low on the bulkhead, but take your point about needing a different cable. A good inline filter is a good idea. I have attached a pic of an installation that I think is one of those inline fuel treatment things, if anyone recognises it?
