I am restoring an engine for a Bagh X 1980 from this:


to this:



I have not yet restored the original fuel pump, and I don´t know if I should.
Would it be better to install an electric fuel pump, and if so, where?
How do I plug the original pump?
I would appreciate any ideas!
Thanks!

Lasse

Waouh Lasse !!
Congratulation for the work on your engine.
It is like new !!!
I can't answer at your question, i'm not brainy enough.
So i translate for my french friend, don't worry, you will have
reply from them very quickly now.
Je traduis !
Si quelqu'un peut lui donner une réponse (même en français, je
re-traduirai ensuite.)
Citation :
Je n'ai pas encore restaurer la pompe à essence d'origine, et je ne
sais pas si je dois.
Ne serait il pas mieux d'installer une pompe à essence electrique, si oui
donc, ou ????
Comment dois-je brancher la pompe d'origine ?
J'apprecierai toutes idées.
Merci.
Lasse
Fin de citation

Les pros.....je vous laisse répondre.....

i think the original fuel pumps are still available - thats a part that one rather buys new. and i even don't know if its possible to overhaul an old pump.

an electric pump can be interessting when the engines suffers of starting probs when hot. usually those pumps are delivered with a security-switch so that it only works when engine is turning.

Felicitation pour le travail
Pour la pompe, l'origine suffit à mon gout.

A+

According to Romop, the original fuel pump is quite

good and enough.

Hi Lasse,
Nice looking engine,
I made an experiment with a Biltema electric pump last year. Worked fine for the 10 km the pump worked.
The original pump is probably fine as long as the engine is running but filling the carbs puts a lot of strain on the starter motor.
On previous cars I have used an electric pump conected in paralell with the mechanical which has worked very well. I think I will go the same route with the Bag if I can find a reliable pump.
As I understand it the return line from the original pump was to prevent air locks by circulating a small amount of fuel. An electric pump can be relocated away from the engine (I put mine next to the HT coil) and should not suffer that much from over heating. So it should not be necessary to have a return line from the electric pump.
Regards,

Stig

Pourquoi gacher une si belle restauration en installant une pompe non conforme a l'origine .

Oui, vous avez raison naturellement!:oops:

And as the original pump seems to be a reliable pump, I will use it.

Hi, I want to raise this old question because at that time it was not fully answered and I think it is important!
First, there must be an automatic emergency shutdown! If you become involved in an accident and are unable to shut down the engine, the electric pump can supply the entire accident site with fuel!
Secondly, you need a return line so that the float and float valve will not be overloaded as the pump is fully fed at all times!
  It is much easier to use the original pump, which is a reliable design and usually lasts the life of the car.
Emergency shutdown is the strongest argument against retrofitting an electric pump.

Hello Peter,
Good reaction, a bit late but this subject can always be useful.
A way to stop this, is to power the fuel pump relay through an oil pressure switch, which will close when the oil pressure goes up during the start.
If the engine does not spin, no oil pressure, no power to the pump , so no fuel pressure => safe

Sorry Peter, but I can't tel this in english. Perhaps someone will translate it.

Quand l'auto n'est pas démarrée tous les jours, pour peu que la batterie soit faible, le temps froid et le démarreur fainéant, la pompe à essence électrique trouve pourtant tout son intérêt.
Il m'est souvent arrivé de vider la batterie avant de remplir les 2 carbus, et là j'aurais vraiment aimé avoir une pompe électrique. La question de la sécurité m'a toutefois retenue.
A la place, j'ai acheté une poire en caoutchouc à insérer dans le circuit pour remplir à la main les carbus avant de donner le premier coup de démarreur. Je ne l'ai jamais montée car les diamètres de raccordement ne correspondent pas tout à fait et je n'ai jamais trouvé comment rattraper la différence.
Mais finalement, côté sécurité, est-ce plus raisonnable ? Comment va vieillir ce caoutchouc plus fin et plus fragile qu'une durite ?
Quelqu'un a-t-il de l'expérience avec ce genre de poire ?

Je ne suis pas très adepte de la poire dans un compartiment moteur très confiné et qui chauffe comme celui de la Bag. Si le circuit est bien monté, bien étanche, le souci ne se pose qu'au bout de plusieurs semaines. La pompe électrique est top, mais l'installation a un coup, effectivement si on veut faire un circuit sérieux et sécuritaire. Sur une Bag, c'est absolument indispensable car prend feu et ça brûle bien

I'm not for a pear mounting in Bagheera'engine compartment, it's confined and it gets hot. If the fuel system is built correctly, full sealed, the problem only arises after several weeks. The electric pump is great, but parts are cost if you want make a serious and safe circuit. On a Bagheera, it is absolutely essential because it catches fire and it burns well
