After 18 years and 170,000 miles I had a factory injector failure. I thought I'd try these out. The top brown o-rings were torn and deformed when first installed. I had a gas geyser sprayed on my engine. Yes, I soaked them in a small jar of gasoline for 4-5 minutes before attempting to put them in. I had a few o-rings left over for another project that worked and within 5 minutes my machine was running fine again. I will update if there are any problems in the future.
