Sometime in recent years, B&S changed their fuel pumps from the old style "rectangular" style to the newer "round" style. I had some fuel leakage on my older generator with a 10HP B&S motor fuel pump last year, and had to replace it with one of these newer "round" pumps. I also have this "round" pump on my Husqvarna 24HP riding mower. These "round" pumps seem to be very hard to "prime" and get the engine running....so much so, that I have gotten into the habit of giving the air filter a quick shot of Starter Fluid to get the engine running quickly....instead of wearing myself out pulling the starter cord on the generator, or running the battery down on the mower. Am I unique, or has anyone else noticed that these round B&S fuel pumps are a "pain"? Has anyone found a secret to starting the engine more quickly with these pumps? Even the owners manual on the Husqvarna mower says the engine should start "within 15 seconds"....that seems ridiculous to me. Unfortunately, the old "rectangular" pump I had on the generator had a cracked body, or I would have rebuilt it....and I haven't found anyplace on the Internet which still has any of these old style pumps for sale.
