Fuel tank drain plug

[nthomas1]

Can anybody tell me the size and type of wrench needed to remove the drain plug from a Series 2 Coupe petrol tank?  I read somewhere that it is 14mm, but is that correct, and is it hex or square?   I want to order the necessary tool in advance of my return to the UK so that I can waste no time in removing the petrol tank when I get back.

Also, if anyone has the time to read my latest post on the thread "Progress Report on Fulvia S2 rebuild", I'd be very interested in any information on the couple of questions that I posed there regarding topics I couldn't find any information about in the forum:  (A) removal of the filler pipe (with regard to how it's attached where it passes through to the fuel cap), and (B), the method of connection of the fuel flow pipe that takes fuel out of the tank.  Please forgive the clumsy descriptions!

Norman,
I've just looked in my Tavoli but the illustration only shows the pllug upside down so you can't see the shape, but I'm pretty sure it's recessed, and no size is indicated in the text either, sorry.
I think the coupe is similar to my Berlina where the pipe is fitted by the fuel cap, on mine there big a rubber gasket with a hole in it, that is held in place by a painted/Enamelled plate, that is fixed in place by screws, and has a hole which the filler pipe passes through.
On my tank there's and outlet pipe through which the fuel is drawn from the tank, a flexible fuel hose is connected to this and held by a worm drive clip, the other end goes to the solid fuel pipe and held with another worm drive clip, this pipe then goes to the front end of the car, but bear in mind I have no fuel return system, so yours might be slightly different.

Hi Norm

I removed a tank from a 1969 S1 Fulvia Sport at the weekend, not sure how similar it is to a coupe, I am still getting to grips with these cars and the different models/series.

The drain plug is the same size as the engine sump hex plug. I didn’t have one so made one out of a bolt head, a few nuts and spanner, although it was very tight. I can measure it tonight. The filler end (neck) of the filler pipe unbolts from the body, there was a big washer that clamps the neck, also there is a seal on the floor of the boot.  The other end was fixed onto the tank with a large notched nut, so although a special tool is needed to remove this, I found a simple chain wrench worked without any damage.

It is sump plug size but it will need to be a good fit - using the tool in the Fulvia tool kit is ok it it has not been rounded off.

Thanks for that info. Sounds like it is hex shaped and female?? It would be great Julian if you could get the measurement for me. Cheers.

[Jay]

yes 14mm, it was very tight although i syphon most of the fuel out.

[nthomas1]

Great, thanks for that. Can you confirm that it is hex shaped and female.

[Jay]

Yes it's a hex and tool you want is a male 14mm Allen Key type tool, socket, as the plug is female.

[nthomas1]

Great.  Thanks for that feedback.

I use a 14mm tool that fits a 15mm socket, see attached photo, it was the first tool I bought for my Fulvia in 1984, via Snap On or similar supplier.

Looks a good option Neil. I've just found one on Ebay and have ordered it.

I use a 20mm length of 14mm hexagonal bar welded to 300mm length of MS flat bar ..... it was what we had in the workshop!!!! And it was free!!!!

PS it appears that 14mm hex is/was the Lancia default for sump plugs ..... mine is used on the B20, Appia and (I think) the Augusta!!!!

Pretty sure this is the tool I use for the Beta sump too. I would have bought it in 1991. I recall the other end worked on the plug of my 205 Gti.
