Question help-fuel pump

Hello All,

Cant believe this has happened but the trail of events is weird. Sometime back after returning from a ride, I parked the bike and walked a few steps away and hear a sound I never wanted to hear. That stupid stand or stupid me ..... the bike slipped off the stand and fell onto a car. The tank got badly chipped and the side panel also scuffed. Tried to start the bike to check all is well inside. There was smoke and a burning smell coming from under the tank fearing the worst I switched it off. On removing the tank it turns out that the female quick disconnect had cracked and thankfully I had already had the metal one from Cag (thanks Cag). Unfortunately on trying to connect the male female disconnect the black O rings got pinched and broke. Damn .... tried quite a few o rings but all of them leaked. Finally wrote to Noel and the Knurl shipped them out immediately. canít thank him enough. Once that was fixed we tried checking for leaks and the moment the fuel pump primed there was a leak from the threads on the fuel pump. While trying to fix this the mechanic helping me out put some glue (silicon type) near the threads so the leak would stop and we can check if everything else works fine. Now I would like your help on 2 problems.

1. The leak on the threads needs loctite I think. Donsy mentioned Loctite 577 on his thread for the metal quick disconnects. But if there is any other way to stop the leak please advise.

2. The fuel Pump stopped working in between all this. Checked fuses, battery fully charges, cleaned fuel filter, checked current on the power cable, checked pump on direct current and the pump works but once on the power cable there is nothing, after checking with direct current on the pump and re-fixing it on the power cable there is a click but thats it, the pump wont prime.

Now I do have the older SPU/CPU unit. The one with the blue back but all electricalí s are working fine. Sometime back the high beam, low beam switch played some tricks, not sure if its the switch or something else but the high beam light on the dash is always on. No matter if I am on low beam or high beam and this happened a few months back and there was no issues with any electricals.

Thanks for all the help.

Just a stupid question... do you have an alarm? When my fuel pump did not work anymore we searched 3 days for it and it was only the alarm...

What a beast of a motorcycle!
It growls and rages and flies across the tarmac like a wild animal that has escaped the confinement of a cage and after merely waiting restlessly until the release, will not endure being locked up ever again.


Skye I miss you. L'essentiel est invisible pour les yeux.

Angry leaker?

Sarge;
1.instead of the 577 i'd use Teflon tape....
use 2 complete wraps 3 at most
point the fittings threaded end away from you, put the tape on the bottom side and rotate the fitting clockwise

2. sounds like the SPU....... another blue backed POS bit the dust

i think Andre at StarTwin has the best price for the SPU
check CAG's sticky at the top of the page for the correct part number

Thanks Noel, anything else I should check before I order the SPU. I dont have another Brutale in the area that I could check with. Does the 312R and the brutale 750 have the same SPU?

OK so now I know that the F4 does not have an SPU.

Thanks Donsy.

Sarge, I'd just buy a new spu anyway, you are going to need one at some point... As Noel said, try www.startwintrading.com

I think the Brutale 750S and 910S have the same SPU and the later bikes have a different one.
