Electric Fuel Pump 12v Electric Transfer Universal Low Pressure Gas Diesel Fuel Pump 2 5-4psi HEP-02A

This was the answer to my no fuel problem causing a no start issue. The mechanical fuel pump on my John Deere Z320R mower stopped pumping after 29 hours of operation. I replaced the fuel pump and it did not fix the issue. I then replaced the carburetor and it did not fix the issue. I then installed an electric fuel pump and was able to get fuel to the carburetor and the engine started. I do not know what is causing the pulse line to the mechanical fuel pump to not work. There is no vacuum on that line from the mechanical fuel pump to the inlet manifold. I did check the line for obstructions and found none. Its a mystery as of now but the electric fuel pump fixed the issue! Read more

Used this great little pump to defuel and then refuel a kerosene tank. it took a little over an hour for each process and worked nonstop. I lengthened the wire to reach the 12v battery easier with no problem. Pump was not very loud and did not get hot like i thought it would. Very surprised it work better than I expected. Read more

I rated this a 1 because it develops too much pressure. It is advertised to be a "2.5-4 psi", but it developed almost 9 psi. It worked, it pumps well, and is a great deal for the price, but it would not work as a pump for my carbureted Briggs and Stratton engine. At 9 psi of pressure, it over-pressured the carburetor needle and seat and flooded the engine periodically. It caused the engine to stall and stumble. I finally figured out the problem was this pump. I replaced it with a Facet pump I had that tested close to it's advertised pressure of around 2-3 psi, and the engine runs fine. My advice is don't use this on a carbureted engine. Otherwise, it is a good value for the money. The pump ran great and pumped well, too well for my application. Read more

Great quality Read more

UPDATE; Received replacement pump and it still floods a bit initially after starting. I took the carb off and used a small drill to improve the brass needle seat seal and while it will overwhelm the needle valve/float, it is usable once running for a minute. It is certainly more than the stated pressure, however. There is no way that any float type carburetor could control just how much pressure this pump is pushing. It is far more than 4 PSI; I can barely stop the flow with my finger over the end of the outlet hose. I am going try to exchange it as I believe it may be defective, it never shuts off nor controls pressure to 4 PSI. Fills my air filter and runs out the back instantly at high flow. Maybe it has a check valve that isn't working? I'm not sure but I will update when I get a replacement. I never had any issue with my pulse pump and I removed the carb and the needle valve is working perfectly as I cannot overpower the needle valve with all the pressure I can muster with my mouth, which is more than 4 psi.
