What are the main features of the 2CV tank?
There have been two generations of fuel tanks in the history of the 2CV. The first model that equipped this mythical car until the very end of the 1960s was made of metal and had a capacity of 20 litres. It was replaced by a 25-litre plastic tank from the 1970 model year until the end of the 2CV's production in 1991. The dimensions of this plastic version are 43 cm long, 39 cm wide and 19 cm high. The diameter of the filler tube is 55 mm. Although this tank was used identically on many vehicles derived from the 2CV, such as the Mehari or the Dyane, some additional tank models were specifically designed for the Mehari 4x4 and the Acadiane. Their sheet metal tank has a distinct shape and dimensions (length 570 mm, width 200 mm, height 290 mm).
These different models, including an offer of original parts for them, are available on our website.
What are the parts dedicated to the 2CV fuel system available on mehariclub.com?
This section offers you a unique choice of parts and accessories for everything related to the fuel system. Among the characteristic parts is the fuel pump. We sell four models of fuel pump to be selected according to the year of manufacture and the engine of your 2CV (375 cm3, 425 cm3, 435 cm3 or 602 cm3
). Among them a pump, specifically designed for the oldest 2CV cars, which is equipped with a priming lever allowing to manually re-prime the fuel system as it existed on many cars of this period. Our original fuel pump for 435 and 602 cc engines, made from the historic tools of the double chevron brand, is exclusive to the Mehari Club Cassis and is one of our best-sellers. Remember that these 2CV fuel pumps are all mechanically operated by the engine and not electrically as on modern cars.
You will also find in this section rods and spacers to mount the fuel pumps, fuel gauges for 2CVs powered by 12V or 6V but also various hoses, sleeves, connectors or fuel hoses. And finally, several models of fuel cap with or without anti-theft key, in plastic or chrome steel.
How to fit a 2CV tank?
On our technical website you will find all the information you need to fit a tank to your favourite Citroën. You can consult directly online an instruction sheet
dedicated to this subject or download it in PDF format. This is a relatively simple operation that can be carried out in barely half an hour, provided that access to the tank has been cleared beforehand. Before fixing your tank on the chassis, you must first install the fuel gauge to which the fuel hose will be connected. Don't forget to connect this gauge to the ground by means of an electric cable of about 30 cm. To do this, simply screw this cable to the chassis at the level of the tank mounting bracket, thanks to a flat crimped lug at the end of the electric cable.
The tank is fixed to the chassis and the rear crossbar with 07 x 30 mm and 07 x 20 mm screws, four 07 mm diameter contact washers and four specific plastic washers sold on this page. The fuel tank inlet is coupled with the fuel filler neck on which the fuel cap is directly mounted. Note that the fuel filler neck on the 2CV is the same as that used on the Dyane, but it is different in angle and length from that of the Mehari, although the diameter is similar (41 mm at the neck and 55 mm for the cap mounting flange).
