Is there anyone not running a second fuel pump on an Argo with a Briggs and Stratton Vanguard? Every Argo I have seen has a facet pump at the tank.
I have been through 3 facet pumps that have a fuel pressure regulator set to 1.5 psi. Each pump has started smoking and failed. The time of service has varied from several months to a couple of weeks to days on one pump.
I have removed the facet pump and tried to run just the vacuum pump on the motor. It does not draw any fuel. I replaced all the fuel line, vaccum pulse hose, filter and pump, primed the line and I still get no fuel. The line is patent and I can siphon through the hose without problem.
Any ideas? |

I got it figured out.
I put a can of gas up higher to see if it would gravity feed. I was still not getting fuel. The pump is not a mechanical type but a vacuum type. Since I was not getting fuel by gravity I pulled the top off the carb. The bowls were dry. So I lifted the gasket and pulled out the floats. The carb started filling up with gas. So the fuel inlet needle was stuck. So since the pump couldn't push against the needle it was not moving anything.
I reassembled it and it fired right up and has been idling outside for about 20 minutes now. I'm going to take it out for a ride and see if it will run up and down the hills with just the mikuni factory pump.
Dennis thanks for the suggestion. I had removed the fuel cap too, thinking that was a problem. |

There is a B&S electric pulse pump you can get for the 18hp engine from any dealer. We removed the vacumm type, and installed the pump in it's place. We wired it into the brake fan line as we wanted to make sure we had the engine running when using it to avoid any over run. The pump is only 1psi and it works great on our Bigfoot, and an added bonus of fuel getting to the carb even on steeper angles. To mount the pump, we used 90d angle brackets and used rubber mounts for shock absorbtion. |
