Where do I get one of these?

Yes, same as the one @Norris found, needs 12mm id, however. Thanks

 

Saw it off

 

Why didn't I think of that?

 

There's a 12mm one

Sorry, that's 12mm external, 9mm internal

 

No, I think that's right, it's the hose that's 1/2 " id, so it needs a 12mm barb.

 

I'm sure if you search for "barbed hose connector bulkhead 12mm brass" you'll eventually find one

 

It was the words "bulkhead connector" I was missing, thanks. When I just did "barbed hose", I was swamped and had pages of results

 

I put rubber grommets in my filter lids and just pushed in a right angled 3/8” NPT elbow - see blue things in my eng comp pic. Fit well, and no nuts to drop into the engine.

 

One of these bad boys?



Doesn't necessarily save money if you use a fancy fitting but the elbow will be easier to attach the hose to

 

Yes! I think. Will check later.

Those fittings are great. Bit pricey, but there’s such a wide range if they come from the same folk I got mine from. Hate brass stuff - looks like you’ve had the plumber in...

 

Rivnut from the top so it can't fall into the carb, simples.

 

I like @snotty's idea of just pushing a coupling into a hole with a grommet in

 

Fits nice’n’tight. I’ll get a pic later.

 

I am going to get my filter lids off later and assess the situation I think I have ridges on the top

 

You could drill and tap them 3/8” NPT. Nice size for breathers (about 1/2” ID).

 

One of the buggy guys gave me a tip - use plastic fittings as if the nut drops off it won't damage the engine like a metal one would. Seems to make sense.

 

1/2" barbed fittings come in a range of internal bores. Get the biggest you can so you don't clog it up at the last hurdle. 10mm minimum?

 

These look like the monkeys

The monkey's...water butt ?

 

These are the folk. Loads of good stuff, and in a choice of colours to match your mood...
