I followed this and after replacing the fuel pump an initial improvement was seen. For about 20km. After this my bike went to shit again. It was fucked (the fuel pump) so I am not complaining about the fix. However, my problem also involved the fuel pressure regulator as well so my problem wasn't fixed just by replacing the fuel pump. My bike is now running perfectly. After I rust clean my tank I'm going to get it dyno tuned. The Suzuki manual for the Bandit has a warning not to remove the fuel pressure regulator. Probably because they charge around $180 for a new one (which a mechanic would install in 5 minutes like I did) and I got one for $35 on Amazon Prime. Hope this helps any fellow Bandit riders. My bike is an Australian delivered 1250S K9. 72,000km.
Hey Paul, although my 1250 FA doesn't suffer from a failed fuel pump I'd like to thank you for this very informative video, well done! Greetings from Germany and always remember, the most problematic part on a motorcyle is the nut wich connects the seat to the handle bars. ;-)
Good on ya mate. Us blokes and sheilas who have these bandits and need to replace the pump and filters thank you for taking the time to show us how to go about doing it. Cheers 👍
very useful video. replaced the pump within a half an hour because of the video. Bandit runs smooth again ever since. Used a replacement of Quantum Fuel Systems.
If you are going that deep into the fuel pump it is worth checking how dirty the fuel filter is in the pressure regulator housing. These things can block really bad and stop the bike from reving. I clean mine with a small ultrasonic cleaner but I believe carb cleaner work well too. Very hard to see inside, stick a small q-tip inside and see if it comes out dirty. The screws go on first and the mesh filter housing just clips over the top, makes it a bit easier to get the screws in.
Bonjour merci pour la vidéo, mais tu as oublié un autre filtre qui se situe à la sortie de la pompe dans le boîtier du contacteur de pression , ce filtre se bouche on ne peu pas le changer et difficile d accès il faut faire tremper ce boîtier dans du pétrole et avec un gOupillon pour nettoyer les dents le brosser puis souffler au compresseur. J ai eu cette panne problème d accélération j avais changer l'aéroport motEUR DE LA POMPE LE FILTRE A ESSENCE LE CONTACTEUR DE PRESSION JUSQU à ce que je découvre ce filtre qui était bouché 👍🏼 depuis la moto refonctionne
very good men, in Colombia or latinoamerica no challenge or replace parts, if is good, not challenge, ajajjajaj, hasta que no se queme no lo cambian. llevaba buscando un video de estos por bastante tiempo.
You can check a couple of ways.. Easiest is to turn the ignition to switch to 'on' and see if the pump runs for a few seconds. If nothing, double check the pump relay and the tip over (TO) switch - both under the seat.. Also, unbolt the tank and tip up. Uncouple the lead wires to the pump. Get a 12v supply and put the positive on the Y/R wire and the negative on the B/W wire. If it runs, its something else. If it doesn't, it's most likely the pump. Good luck!
Parked in the sun? Those tanks are sealed tight and get hot easy.. Make sure your vent tube is not kinked or restricted.. If it's pushing gas out try opening fuel cap to relieve pressure. Unless you're riding, careful on how much you fill it. Those are the most common
I'm having problems with the bike running intermittently good and bad. Bike sat for years, 2008 Bandit 1250. Removed tank, removed fuel pump, dumped fuel, put new fuel in, same problem. Plugged injector? it cleans up and runs normal at times but generally running line poop. thank you:)
Injectors could definitely be the culprit... The fuel will form varnishes while stagnant. I am assuming you changed the fuel filter etc while replacing the pump? If not that could be part of the problem. What I have used in the past is an additive called 'sea foam'. While it is certainly not the miracle additive I have had pretty good luck with it. Its purported to remove the varnish and crap from injectors. I have become somewhat of a believer. Any auto parts store carries it. I have several bikes, some quite old that sit for long periods. Try pushing a tank or two of fuel with that in there before pulling hardware off. Good luck, let me know how things turn out...
Thank you! I removed the pump to drain the tank but the pump works fine. Amazing I have an electrical device inside a fuel tank right between my legs and never knew!? I'll take the injectors off but not sure what to do with them.
Ther is a screen in the fuel regulator that more then likely needs to be cleaned. Best way to clean it is with hot water and a soft wire (speaker wire). Make sure to clean both side of the screen. One side is hard to see. I’ve had to fix a few 1250 bandits with this problem
Cody, this is spot on. I'd bet the majority of pump failures are due to the internal steel screen filter in the fuel pressure regulator housing getting clogged. In my case, the external mesh filter disintegrated and completely packed the steel mesh filter. I'm surprised the bike ran at all!
salve ho fatto la procedura da lei indicata per la sostituzione pompa, ma la moto mi perde potenza a motore caldo in accelerazione a giri alti.. .... può darmi un consiglio? grazie
Could be something as simple as a gas cap not venting well. I am assuming you changed the fuel filters while you had it apart. From limited info I would look at fuel starvation, caused by heat.. good luck
There is a small mesh screen in the plastic part where the pump fits into which also should have been cleaned out if I remember correctly. I was reminded of this by another commenters
grazie mille per l'informazione.... proverò nel modo da lei descritto.... il mio meccanico non vuole fare questo lavoro e vuole farmi cambiare tutta la pompa... costo 480 euro....
avrei un'altra domanda... nel caso dovessi acquistare una nuova pompa carburante, la pompa della 1250 si può montare su una Suzuki Bandit 650? grazie ancora..

4:00 Someone's grown a third arm. Can this be done as one person or safer to invite a mate around for a hour or so?

please can a Bad fuel pump cause F1 Red lihght error on my suzuki bandit 1250cc
Thank you very much for sharing this with us! greets from Austria
Fantastic, thank you from me down under here in Australia. I too have a 2007, great bike (bullet proof).
Great instructional video! I'll be doing this myself now, so thank you!
Nice video!
Seems to be the only real problem of this bike! Rest is solide!
Brilliant video most helpful thank you, its always good to know theses things....
I very enjoy to see this video. It's very clear and nice to follow
Thank you!
this video taught me a lot of things about my bike, which is a 650.. but it's much the same except for the engine:)
Thank you for the video. Most helpful.
great tutorial...
Thanks
Well done! Thanks!
is this an issue on all 1250 models
Thank you for sharing!. Great vid.

Be sure that the fuel screen in the tank is not plugged that fixed mine. I had about 17000 iced on at the time.
Where is the fuel screen? Is it inside the tank also?
Fantastic video! Thanks!
Great job man. You really deserve a scotch.
very good men, in Colombia or latinoamerica no challenge or replace parts, if is good, not challenge, ajajjajaj, hasta que no se queme no lo cambian. llevaba buscando un video de estos por bastante tiempo.
very good video, how did you know it was the fuel pump that not working.
What is the correct way to make sure that it is the pump.
You can check a couple of ways.. Easiest is to turn the ignition to switch to 'on' and see if the pump runs for a few seconds. If nothing, double check the pump relay and the tip over (TO) switch - both under the seat..
Also, unbolt the tank and tip up. Uncouple the lead wires to the pump. Get a 12v supply and put the positive on the Y/R wire and the negative on the B/W wire. If it runs, its something else. If it doesn't, it's most likely the pump.
Good luck!
Did your bike just caught out and wouldn't start Got a 2008 Suzuki bandit 1250Tone over but will not start
Yes, just quit. Check the spark. If good, fuel is most likely culprit. You should hear fuel pump click on when ignition is turned on.
Great video. Enjoy your scotch
So after 5 years how has the pump held up?
I sold the bike a couple of years ago. It was fine then.
If my overflow is constantly pushinging out gas what would be causing that. I'm looking alot of gas there
Parked in the sun? Those tanks are sealed tight and get hot easy.. Make sure your vent tube is not kinked or restricted.. If it's pushing gas out try opening fuel cap to relieve pressure. Unless you're riding, careful on how much you fill it. Those are the most common

@@luckylucio1973ciao hai risolto poi ? 19:07
The only minor problem is I won't run the pump dry. They need fluid to cool them. A short run should be ok, but people need to keep this in mind.
True! Good point. True for almost any pump. Thanks
Where did you get the aftermarket fuel pump? Thanks
Amazon. Just do a search and you'll have more choices than you'll know what to do with. Mine was a Highflow I believe
Nice one mate.
you can video about of injectors of bike' saludos
your great
nice job *thumbs up*
