A10 plunger fuel tank

Make sure you put a blanking plug or old duff taps in the outlets though!

I bought some blanking plugs for the tap spigots but still needed to buy a thread tap to clean the threads further in.


I'd be happy to lend out the plugs and tap if anyone here needs them.

I've got a melty liner in one of my tanks.

If you do go with one it needs to be able to cope with at least 10% ethanol in petrol.

Hey GB
Having just got a new replica tank, I'll need to to run a tap through the fuel tap threads before I fit them. Very generous offer on the loan but I'd prefer to buy the necessary tap but could you tell me what size I'll need to order please.
Cheers

I think it's a BSP thread. I'll need to find the tap before I can tell you the size. If no one gets back to you, I'll tell you later.

If that's an Indian tank then it may be nothing like GB's original. Am pleased with my tank but the taps took some fettling. Can't remember what the thread was sorry to say but i did fit an off the shelf adaptor and forced it in with lots of tank sealer and it's been good for years and lots of miles now. A more patient or sympathetic owner would probably/definitely baulk at this.

Cheers GB and Jim, I can definitely see some fettling occurring over the weekend!

[Greybeard]

Sorry for the delay getting back to you. I've only just remembered to look for that tap.
It says BSP 3/8 - 19 on the side.

The offer of a loan of the tap is still open.

[Minto]

Thanks GB, that's very generous of you. If I message you my address how do you want paying for postage? I'll post it back the same day it arrives.

Really needs to be BSPP, BSP is tapered whereas BSPP is parallel.

Are you thinking of the tap spigot maybe?

[trevinoz]

I am thinking about the thread in the tank.
I am not in the shed at the moment and I am thinking about swinging arm tanks which have a reducing bush which screws into the tank and if my memory serves me well the bush is 3/8 BSPP to 1/4 BSPP.

No it's not. BSPT is the tapered thread fittings (of which there are none on a BSA) but the tank spigots are BSP (which is a parallel thread) not BSPP.
BSP and BSPP are not the same.

The tap is in the post, First Class.

I don't want you to pay me anything. If you would like to donate an amount to this forum of at least your return postage charge, I will be happy.

No need to rush it back; I'm not planning to use it for the foreseeable future!

[Minto]

Thanks GB.
Ill look into how to make a donation
Cheers

Rex, According to my thread chart, you are wrong.
I will grant you that I should have called the tapered form BSPT but the parallel form is BSPP, unless my thread book is wrong.
