Bonjour a tous Technique et mécanique 1800 - remplacement pompe a essence mecanique par une electrique 270c

Je voudrais remplacer la pompe à essence de 1100 GL de 1981 par une pompe électrique de 1200 GL .

Est ce possible ?
Si oui, comment doit je mis prendre pour les branchements
Y a t il quelqu'un d'entre vous qu'il l'a déjà fait( des photos serai le bien venu, merci par avance )
Peut être d'autre conseil a ce sujet, merci

Jamais fais mais je pense que c'est possible. Enlever ta pompe mécanique, boucher l'orifice sur la culasse avec une pièce maison. Branchement de la pompe et relayant un + après contact de l'allumage (alimentation depuis la batterie avec protection adéquat). Brancher les durites et ça doit faire. Peut-être vérifier que les pompes régulent à la même pression....

Bonne mécanique

Oui ça peut se faire, notamment si la pompe mécanique d'origine est HS car le seul intérêt est de ne pas devoir faire tourner le moteur au démarreur pour remplir les carbus lorsque la moto a été un long moment sans tourner.
J'avais eu un échange avec un américain qui m'avait envoyé sa méthode de montage d'une pompe électrique mais je ne l'ai pas encore fait, ma pompe mécanique fonctionnant parfaitement.
C'est pour un 1000 mais le principe est le même.

Installing an electronic fuel pump on a GL1000
If you choose to follow any of my methods, you must do so at your own risk. I am not an expert fuel
pump installer or an engineer. I hope my research and this article helps you overcome some of the
challenges with this task.
The first challenge I had was selecting the best suited fuel pump. I won’t bore you with the details here,
but here are several fuel pumps that should work fine. I have personally used the K&N 810400 and the
Faucet 40163 with excellent results, but if I had to select one today I would probably get the 40367 or
the 40352. With the cube type, you will need to make a bracket out of ¼” aluminum.
K&N 810400 fuel pump 1 - 2 psi and 15 gph
Facet-Purolator Cube 40367 or 40352 1 - 2 psi and 15 gph
Facet-Purolator Cube 40163 1.5 - 2.5 psi and 17 gph
If you use the 810400, you can leave the original fuel pump in place. Just make a bracket and mount the
pump where the original filter is located. If you use a cube type you will need to remove the original
fuel pump and install a ¼” aluminum plate to cover the hole. This homemade plate bracket will be used
to mount the cube pump and also cover the hole.
The next challenge was deciding on how to automatically turn the pump off in case of an accident. The
mechanical pump only pumps when the engine is running so I decided to do the same with the
electronic fuel pump. This is controlled via an oil pressure switch. If there is no oil pressure, the pump
does not run. I replaced the original oil pressure switch with an AirTex 1S6554 (PS132) to accommodate
this feature. Note: I did install a bypass button that you can press to force the pump to operate. This is
useful if the bike has been parked for a week or so and you want to fill up the bowls prior to starting the
bike. The button is mounted near the fuel pump.
The below steps and pictures will help show the process. This is not difficult but it does take a few
hours.
Parts list:
1ea K&N 810400 fuel pump or a Facet cube type like the 40367
1ea PS132 Oil Pressure switch (AirTex 1S6554)
1ea A Momentary Press Switch (12mm Waterproof momentary ON/OFF Push button Mini Round)
1ea 1 new original type GL1000 fuel filter
2ea 1/8" NPT X 1/4" Hose Barb Brass Straight Fitting
1ea 2 feet of high quality 5.5mm – 6mm fuel hose. Get cloth stranded if possible.
1ea 6 feet of 16 gauge stranded wire
3ea Insulated Female Push-On Wire Terminal Connector 90 Degree
1ea Quick Wire Splice Connector
1ea Bracket material. Metal for a bracket, a bolt and a nut
Steps:
1. Remove existing fuel filter and hoses.
2. Remove rear engine mount and loosen the breather bolt a few turns. The bracket you make will
slip under this bolt. See picture below:

3. Replace oil pressure switch with PS132 type.
4. Make a bracket for the electronic fuel pump. The bracket will be mounted to the breather bolt.
See pictures below for details:

Notice in the picture above that the black wire goes to ground. The red wire will be connected
to one side of the oil pressure switch.
5. Mount the fuel pump on the bracket and then mount the bracket to the engine as shown below:

6. Connect the ¼” barbs to the fuel pump.
7. Connect the hoses. Route the hoses across the old fuel pump fuel connections to make it look
like the original configuration.

8. Make a bracket for the switch. A good place to mount the switch is on the large frame bolt. Use
a waterproof, momentary on pushbutton switch. Connect two wires to the switch that are long
enough to reach the oil pressure switch. See pictures below.

9. Now for the wiring. Look at the oil pressure picture below. The silver connector is for the
original wire that went to the old pressure switch. Clip the end off and attach a new connector
(Insulated Female Push-On Wire Terminal Connector 90 Degree). The other two are for the
electric fuel pump. When there is oil pressure, there is continuity between these two gold
connectors. The two wires from the pushbutton switch attach to the two gold connectors. This
allows you to short across the oil pressure switch when the engine is not running to fill up the
carb bowls. The red wire from the fuel pump goes to one of the gold connectors and the other
gold connector connects to the blinker module (the white wire with a green strip). You can use
the Quick Wire Splice Connector to accomplish this task.
Wiring diagram:

10. Here is the final result:

Update 7/17/2022:
It would be best to connect to the black wire instead of the green-white wire.
The best place for most people to connect the fuel pump power is the black wire for the regulator. Find
the regulator and trace the three wires back to the connector. You should attach a quick splice
connector around the black wire on the harness side near the connector and install an inline fuse with a
size that supports the fuel pump you select.
