Small Engines (Lawn Mowers, etc.)/fuel pump wont pump


19hp twin opposed wont pump fuel 120 psi on both cyl. new intake, carb, fuel pump, fuel pump body, sump, and valve cover, breather gaskets, also new fuel line from tank to engine with filter, and new pulse line from engine to pump.engine no. is 461707 will run fine if carb is filled with gas through vent holes, but wont pulse fuel pump

Is you fuel pump integrated with the carburetor?

Did you check out this site?

On some of the integrated carbs I have been able to remove the top of the carburetor and then crank the engine and watch the fuel pump pump fuel into the carburetor.

Make sure you keep the spark plugs removed when trouble shooting so the is less strain on the starter and battery.

Let me know if you can take the top of the carburetor off and see the fuel pump pumping or not.

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
