Hi: My loader will only stay running if I loosen a fitting so that fuel squirts out.
Any suggestions
Thanks
Al

There is a screw tap close to the tank under the seat ,perhaps it has closed with vibration over time?
Good luck

If it starts without the return connector.. look at the bottom of it..
U see the glass ball?? Try to look thru it.. if u see black specs around the ball, chances are the “plastic” flex ring in the pumps has deteriorated and is breaking up..
There’s no magic that’ll fix it..
U can try to clean/blow out the checkball and reinstall it but good money says the flex ring is the problem..

Thanks for your advice. I got it going but bogs and almost stops when pushing heavy load. Even trying to turn left or right it does not move like it should
