So the last time out my fuel pump acted up but started working again. Of course I went out to the trailer this past weekend to get some fuel for the lawn mower<G> and the pump would work. So I pulled it out and dug into it. Thinking that there might be something stuck in the pump gears because I could feel the pump "clunk" when I tried to power it up. I removed the cover and didn't see anything of interest. So I dug into the motor itself. What I found was the brushes of the motor were broken into pieces and the parts were keeping the motor from turning. I removed those parts and the motor did run but didn't have enough power for some reason to turn the gears unless I loosened the cover up. I kind of figured there was something else going on with the motor. I could have ordered a new motor but figured between it and new gears and such the price difference was that great, I just ordered a new pump.
If anyone is interested here are some photos of how the pump works.
This is the GPI pump that is installed in my trailer.
Just remove the clip on the fuel inlet side and clip the wires from under the trailer, remove the
clip that is securing the fuel inlet side and it comes right out. Of course make sure all electrical is OFF.
Yes there will be some fuel that drips out.
The Gear cover removed w 4 bolts. The Gear on the right side in this picture has a small
plastic piece in the middle of it that locks the gear onto the motor. Not much to these
pumps.
Gears removed. The motor shaft is sticking out in the upper brass tube.
Gears removed.
To get the motor out you remove 2 bolts from the motor side and remove the cover. You can
remove the insides as well as the outside tube around the motor is now loose and can come out
of the main assembly. The small pieces below the motor are the parts left from the brushes that
broke off inside.
