Hello im new to this sight and hope you guys can help. I have a trx350 foreman fortraks 4x4 1987. The fuel pump went out and was woundering how the pump worked, and what pressure it ran at? dose the pump build pressure then turn off and turn on when needed or is it controlled by the relay. Any help would be nice
Thanks

Bump, I too would like to know this.

 

i have a 1988 trx350d and my fuel pump went out on mine juat a couple of weeks ago, to my knowledge the pump has to be pumping the entire time that the machine is running in order for the engine to get fuel

 

Do yourself a favor. Discard the electric fuel completely, install a Mikuni vacumn fuel pump that you find on an old single carb snowmobile. I've done this and had absolutely no problem whats so ever. If you want more info just let me know.

 

We hope they have fixed by now! this thread is 2 years old....
