right... i've just seen this on ebay... and i know its abit bizarre but i would like to know if anyone ever has fitted something like this and whether it actually made any difference to the running of the car?

Generally sspeaking Joe that looks to me like a high pressure possibly fuel injection pump. You will want a low pressure feed pump for a carb application.

Second, i wouldnt fit an electric pump on a 2CV, the carb has no return system and it will probabbly deliver too much fuel most of the time.

(i may be wrong, feel free to shoot me down, but the mechanical pump on a 2CV has worked for millions of people for many years)

The fleaBay page does say "For retrofitting to carb car, use safety shut-off valve" - but considering it's nearly twice the price as well as more complex and more hassle to fit than a replacement "normal" mechanical pump, I think you've hit the nail on the head with...



What are you trying to do, Joe? What's the problem you're having?

Most common sign of a dying fuel pump on a 2cv is a need to suck fuel through if the car's been sat for a few days. I don't think I've ever had one fail to deliver enough fuel.

I did have a 2cv, where the arm on the underside of the fuel pump had worn, so it started fine and ran nicely...till I came to an incline on a motorway and had my foot flat on the throttle, the engine died!! I would coast onto the hard-shoulder and the engine would re-fire and away again...till I came to another hill The actuating arm that operates the fuel pump from the cam-shaft, had worn enough to allow the car to run perfectly well, till it needed enough fuel to climb a hill, but then allowed the carb to starve, so cutting out the engine.

If you are going to fit an electric pump, which do offer some benefits over a mechanical one, you should fit one like this which were used on many BLMC car's for a long time and are very reliable.

I was helping a mate try to start his MGB the other day. Guess what the problem was...?

Let me guess that the points in the pump were stuck or pitted. But they are easy to clean and replace. The big advantage is that the pump will deliver fuel to the carb without cranking the engine. Really good if the car is left for long periods and the carb dries out. They also have a satisfying tick so you know they are pumping. Never fitted one to a 2CV but have on many cars with mechanical pumps, Oh and an H van. You could try one on your solex

Oh FFS

The mech fuel pump is more than up to the job
ive NEVER seen one wear out and ive been running with the worst cast offs in the 2cv world for over 20 yrs, after a while the diapragm goes usually 30ish years and that can be bodged with a nitrile glove,cling film etc

if you struggle to get a simple 2cv to run adequatley what the f##k are you wanting to bodge an electrical pump in that will just add to the problems!

Joe listen to the advice... if there is insufficient fuel being delivered and as you have stated, the filter apears to be empty(which they all do they never seem to be more than 1/2 full) then you need to get on the interweb and splash £3 on a meter of 5mmID fuel pipe sutable for unleaded. fit it between tank and nylon pipe then end nylon pipe at the lhs chassis with the filter( repacing the metal pipe in middle picture) then new pipe to the intake of the pump and a new pipe between pump and carb

its a job i did today and the tank one takes a bit but the rest ....the coffee didnt even get cold the usual suspect is the tank one simply cause its often ignored as its a bit of a faff.

if the pump doesnt give a healthy spurt of petrol when cranking( pull the pipe off the carb and tuck it in the loop of the dipstick)then and only then should you be asking on here for someone to send you a working pump or get back on the interwebby and get a new one to fit into your new rubber.

new pump fitted presumably to cure dodgy running

but real cure is £3of new pipe needed


and that car was done by a so called "specialist"

noo guys i wasnt thinking about replacing the pump or anything... i didnt know if anyone had ever retrofitted one?

dad was meant to have ordered the pipe today... we were supposed to be fitting it tomorrow.... after even sending him an email with everything he needed to do... he still couldnt quite manage it :/ good job i have tomorrow off....

i did think there would be an overfuelling problem when adding an extra pump!

i was thinking more like an on off switch for the pump as a little boost or something thanks for the advice though guys!

ps - i know i've been moaning, ranting, squealing on about lily not running properly... many weeks of trial and error, all advice has been taken on board, and once fitting the new pipes, im hoping that her problems will finally go away for a while and this pump wasnt an idea of getting around it... plus its alot more expensive than a few meters of pipe!!

but they do quite often
