FUEL PUMP PROBLEM SOLVED!!!!

gusmx5 · March 9th, 2010, 11:36 AM

Hello guys,as i had told you in a previous thread i had a problem with my fuel pump resulting in loss of top speed but overall power of the engine...
Finally today found the time and took it to the mechanic and he took it apart and cleaned.
You cannot imagine what was in there...the fluid he used to clean it came out black...
Finally there is a lot of dirt in the gasoline we use...imagine a this dirt going in the injection system....

Good to hear is's fixed. I wonder if there is a way to filter it better before it gets to the pump. I also wonder if it is the fuel you get there. I have not heard of this over here.

I dont see why you couldnt add an inline fuel filter. I dont think the brutes have them?

If you notice,if you ever take the pump out,inside the pump has its own filter but in the form of a strainer.It is exactly this.If this gets clogged,i do not know if it is the proper word to say,then it is certain that some of this dirt will go into the pump making it not working right.The in line filter you say must be put before the pump so you can avoid all that but you cannot put it because the pump is inside the fuel tank....
As i was searching for a solution to my problem before some time i found a man in another forum who had exactly the same problem and he did the same with me only his fuel strainer was destroyed trying to clean it.So he searched and he found that the strainer from mitsubishi galand year 1985 fits well and he used this.
So take it under consideration if you ever have the same problem....
But i was surprised how my brute changed immediately and i figured that i had this problem for a long time....
Oh,i also changed the flyweights on my clutch...i ordered the stock ones and installed them...

I look forward to seeing pictures Gus. Ive been tossing around the idea of ordering one for a few months now, since I tend to fill my quad with a jerry can
