  • electric fuel pump install

    First off, thanks for all the good info. This is my first post but I've learned alot off this site. I have a 2009 avenger 700. I've read here that there can be a fuel starvation problem on extremely steep hills. We have alot of those up here. I installed an electric fuel pump I purchased from a part number off this site. I wired it so it's powered anytime the ignition is turned on and the fan is energized. Does anyone see a problem with this set up? Thanks for any help.

    I did mine off the key.. not an avenger though. We could be more safety oriented though. Let's think of unpleasant possibilities. The machine turns over and we are pinned/unconscious and the pump is running and gas pouring out of the carb. Or we leave the machine running, walk away from it, the needle and seat sticks open, floods the carb, engine dies, then fuel spills into the vehicle through the carb overflow.

    Fixes? maybe a gravity/mercury switch whatever it's called. Or I thought about using an oil pressure switch in the pump circuit ground,.. might need a relay.

      Thanks for the insight Roger. I didn't think of those worst case scenarios. The literature with the pump showed an optional oil pressure switch to wire the hot through. I think I may order and install one. Jim

        fuel pressure

        i ran across the same problem tonight
        i'm thinking about putting a resister in line with the pump to slow it down, or putting in a return line with a valve so i can adjust the amount of pressure one the main line
