Petrol tap

Postby ianstephens » Thu Jun 21, 2018 2:04 pm

Hello

I wonder if anyone is able to advise me on the correct petrol tap that would have been fitted to my 1935 LH 250cc ariel Red Hunter?

It is has the original type 75 carb and I believe that it should have a copper fuel pipe but I’m having difficulty in finding information on the fuel tap.

Any suggestions on where I might be able to obtain one would be greatfully received.

Many thanks

Ian

In my 36 parts book it shows 5050-30 petrol tap 2 level
5050-32 petrol tap petrol tap (large bore) Hunter models

From that I would assume that Hunters have the single level tap and others have the tap with reserve, however for practical reasons , I have fitted my Hunter with the Two level tap

Thanks Ian, I’ve been trying to find a reference for the 5050-32 petrol tap but can’t find any information on it. Do you know what type it is or have a picture of it at all?

I don't know specifically 1935 or LH but from memory for 1936 the tap had two plungers, the main had a hexagon and the reserve was round and knurled. The Red Hunters had just a more conventional single plunger tap.

If you are looking on ebay or at jumbles be aware that the screw into the petrol tank is not always the same size so you need to check that. Also there are plenty of reproduction taps around which are of varied quality. The originals could be unscrewed easily to allow you to change the corks which is easily made in just a few minutes from a wine cork. The reproductions are often riveted together and it's more difficult to change the cork. If you buy ready made corks from autojumbles they are often too weedy in size and don't usually last for long. When re-assembling after a cork change you need to blow though the tap to see that it's working properly as the cork length when wrong can cause unexpected results.

The attached picture is a reproduction tap and is included to show the general form of the tap.

That is the type of tap which I use 5050-30. But I believe it should be the single level one 5050-32

Thanks both, that really helpful.

Dave could I just ask; how do you cut down a wine cork, do you use a knife and does it have to be a perfect cylinder shape?

Ian S, can you attach one to an electric drill in some way and then use sandpaper, can't remember the 'Holyfield' method - might have remembered it from Amelia's blog.

I've always bought corks Roger, though they are often not much good.
I've got some punches like Eero's though, I might have a go at making some.
cheers
