Fuel pump losing pulse? Lawn Mower Forum

Sep 16, 2020  (Fuel lines, filter, pump, pulse line... not the 2-way valve) No improvement at all. I considered the pick up tubes might be clogged but it behaves the same way with either tank, and letting the mower sit for 20 minutes or so, the filter re-fills from gravity alone. The only thing I can come up with is the pulse line losing pulses.

Need small fuel pump for lawn mower ... - Geo Metro Forum

Jun 05, 2015  The little vacuum diaphragm fuel pump used on many engines is a marvelous device. It's rated to lift gasoline from 4' down, and deliver it to the carburetor at 1.5 PSI. But like in your case, if you're installing an engine that doesn't have the internal diaphragm fuel pump, converting to an electric fuel pump can get ya mowing again.

How to find, fix and install lawn mower fuel pump Briggs ...

A fuel pump is used when the gas tank is mounted lower than the carburetor and gravity cannot be relied on to carry gas through the fuel line. Briggs Stratton pulse type fuel pumps have either a plastic or a metal body and develop pressure using the varying vacuum in the crankcase, which is created by the motion of the piston and the ...

Kohler KT745 pulse pump issue - Lawn Mower Forum

Apr 30, 2021  The engine started back up, ran as normal for perhaps 10 seconds, then shut down. There was no fuel in the fuel filter. I confirmed that the line from the tank to the filter was clear. Assuming that the new fuel pump might be defective, I reinstalled the old pump and still no fuel flow. Reinstalled the old fuel filter, just in case, but no effect.

It does have a shut off solenoid that could possibly shut off when it gets hot. IDK, I don't think it's a carb issue because of how well it runs when cool. Anyway, thanks for the advice. I

How to Know If a Fuel Pump Is Bad on a John Deere Hunker

A fuel pump on a John Deere tractor has a sensor that helps regulate fuel flow into the carburetor. If the sensor is not working properly, the pump will not give the engine enough fuel to run, which causes the engine to backfire and randomly shut off.

John Deere (Kawasaki FD590V engine) quits when HOT. I have a JD 285 tractor with the Kawasaki FD590V engine. It starts runs just fine, but after running for about an hour or more, it just quits.

The first step in the video is to disable the one-way valve located in the valve cover. The branch to the pulse port on the pump is before the new PCV valve. So the pump gets pressure and vacuum, and the PCV system is intact. Posted By: RSD559 on 01/30/18 08:20pm. Finished the install this afternoon.

Strange fuel problem with 33r877 - Lawn Mower Forum

Sep 03, 2020  The fuel filter looked pretty bad so I replaced that and the fuel pump and no change.

Kohler fuel pump - Lawn Mower Forum Jacks Small Engines

Jul 19, 2020  That should work as well. All you need is a pulse. Bottle feed the carb for a few moments. Have someone put a finger over the hose at the carb to see if it is pulsing (which it will be) and if so, then connect it to the fuel pump, fuel pump to the fuel line as normal. Crank the engine on the normal fuel tank pick up. It should run.

Briggs and Stratton Fuel Pump problem Tech Support Forum

The first thing that I can see from the picture is the tubes from the fuel supply and the oil breather should be switched around. The one that comes from the gas tank and has the fuel filter on it should go to the top right hand side of the fuel pump.

Briggs Stratton Fuel pump leaking oil - OutdoorKing ...

Dec 23, 2019  If the only cause of the fuel pump oil problem was a leaky head gasket, that might fix the problem. The second alternative is to replace the crankcase-pulse-operated fuel pump with the current electric one, so both the oil spray and the possibly erratic fuel delivery are eliminated without addressing the head gasket issue.

electric fuel pump Arctic Cat Prowler Forums

Jan 13, 2013  This did not work. What I found because it is a "pulse" pump was that when I pumped the lever on the hand pump, I had to push the pressure release lever on the hand pump each time in between pumping before it would actually pump fuel through (I guess this is the "pulse" part of it). So because of this it will not pump straight through.

Since then I have replaced the fuel pump, all fuel hoses/filter, carb gaskets, spark plugs, air cleaner, Oil/Filter, and other items not related to the engine. Its a pain in the arse to start up unless I use a little bit of starting fluid or fuel splashed in the carb.

Briggs Stratton 18HP engine problem - Houzz

Crank the engine, and fuel should pulse out, and hopefully any crud/water/dirt that may be in there. Then take an Allen wrench, 3/16 I think, and stick in the hole and remove the jet inside and clean it, crank the engine some more and let some more fuel/crud pulse out. Re-assemble, it should run a lot better.
