Quick Q... LPG filling nozzels?

Feb 02, 2005 4 Replies

Just a quickie... (Oh Matron!) Er.. what's the UK spec for the filling nozzles for LPG kits? Is it some sort of bayonet fitting? Just wondering as I'm putting together a DIY jobby from bits. My local scrap yard has two Jeeps with LPG kits but one seem to have a fine threaded filler at, I would guess, 8mm? The other was threaded, but I couldn't be sure it was the same size as it was partly burred. Are these STD UK spec. or can I get an adapter or something? Thanks! Toby


The filler on our Discovery is 8mm-ish and when we fill we use a screw in adaptor. The other end is a bayonet fitting which goes on the pump nozzle. The only other one we hace come across is a very large screw fitting but that was at a calor dealer for filling bottles. Richard

The standard retail pump fitting is a Bayonet, yeah. Some kits use small bore pipe (8mm bore, might be) for the bit from the filler to the tank. Others use approx 12mm bore and flexible hose. The latter is better, fills faster.

There are 2 kinds of adapter, too - the small threaded one looks puny to me, unless it can be supported not on the thread; it'll also make for very slow filling. The ones I have are approx 20mm diameter (I could probably work out what thread they are) and more solid-looking - I've seen the built-in bayonet fittings with this thread inside the end for fitting an adapter.

The other connector with the big screw thread is an ACME screw thread, and is the older style one. I still have this on my private tank, but I've not seen one on a retail outlet for ages, other than in Eire where they're standard.

So, if they have more than one type in the yard I should go for a 20mm diam one? But for ether, I'd need to buy an adaptor to be able to plug in the bayonet fitting from the 'pump'. These are easy to come by? Thanks! Toby

LPG suppliers have adapters. However, you can also get a filler which mounts into the body (presuming enough space behind the panel) and has the bayonet thing built-in, recessed inside the body. very neat. Then you only need an adapter for going to France (and maybe Italy, too) or a different one for going to Eire.
