equivalent fuel pump for the Brute Force

[SRRBrute]

Well I just got done replacing the sock filter with the one from the galant, and ripping the secondary filter up. From seeing everyone else's posts, I was getting excited. Nope! Same exact problem instantly.

Mine is an'08 by the way. Problem is: pressing throttle softly, and/or holding lightly, it wants to either cut off completely or stumble real bad. Is there anything else to check? I'm about ready to take it to a dealer but then wonder if they'll even look at it with that done, and the spark plug wire mod on it. Please help!

Might try the flow test, if not you can order a fuel pump for a 09 gsxr 750 and pull the motor out of it and put it in your housing, there the exact same pumps


I'd rather be riding instead I'm using tapatalk!

yupp, flow test!!!! Disconnect the fuel hose from throttle body put the hose in a graduated glass and turn the key on. The pump should run for 3 sec. Repeat 2-3 times, after each try read the level, it should be 50ml or above. Good luck'

Ok I haven't done this test yet, plan to soon.

Eastexasmudder, do you know if the fuel pressure regulator from the gsxr will also fit in our assembles?

The regulators are different, I just reused my old housing and regulator.Changed the sock and removed the secondary screen. Only thing that was Changed was the motor it self. It's identical to the kawi pump mtr. Just besure and clean everything up real good,pump housing and the inside of the tank. It might not look dirty but mine had some nasty black crap in it you couldn't see till you took a rag to it.

Yeah I'm just not real sure because my problem isn't the same as everyone rise is having. I have good fuel flow at full throttle, my problem is right off of no throttle. I have already done all these other fixes and my symptom was exactly the same. That's why I think it would be the regulator.

Ok well I did the flow test and got over 100ml's each time and almost 5 seconds of running. Don't think the pump is the problem.

What do you drill out the regulator or what for the second filter

You're talking about your 750 right?
Some 08 models had problems with the throttle bodies. One I'm working on now has already been replaced by the dealer. Not sure if it was warranty or recall, but we couldn't figure out what was wrong. There wasn't even a error code to reference.

Btw. Sorry I didn't get back up with you about Albany. Did y'all end up going to possum creek?

[SRRBrute]

Yeah it's on my 750. I think I may have figured it our last night. I adjusted my throttle position sensor and now I can't make it cut off like I was able to do before. So it just needs some testing.

Yeah we went to possum creek. A friend flipped his and my tire fell off, but we had a blast! I think we may end up riding somewhere August 11th weekend so let new know if y'all are interested in that.

Yeah I'd be interested. Maybe I'll have mine back together by then.

ok I did all this with the screen and put an inline filter as stated and now it wont even start any ideas. The fi lite flashes when trying to start it.

Did you install the filter the right way? They only flow one way.

I sure did but I used 5/16 injector fuel line going to try the next size down and see if that helps maybe to big of line and not enough pressure I don't know. When I pulled the line off the throttle body it had pressure and gas went every where.

so I did away with the filter and 5/16 th line and just put 1/4" line on and its doing the same thing so its not the line and filter. But the fi lite still flashes when trying to start????.
Ok it sat for awhile and hit the key and fired rite up then died and wont start again.

Wow I feel dumb it was the roll over switch I had to reset so heads up on that one guys. I had fuel turning the key on but not when trying to start it.:what: I put the filter and 5/16 line back on and took it for a spin around the neighborhood and runs great.

I'm having the same issues. I removed/ tore the upper screen. And replaced the lower sock with the 85 galant part. I deffinetly have good flow now. I get about 2.7 ounces when the fuel pump is switched on for the 3 -4 seconds it runs. I was getting maybe 1 ounce before. But my fuel pressure is right at 33 psi. I know spec is 43 psi. My question is, has anybody found an equivalent pump we can put in place. I havent searched around for the 09 gsxr 750 pump that was mentioned yet. I was looking more towards new that one of my local parts stores might stock or be able to get next day. Thanks in advance!!

I figured this needed to be a sticky.
