The latest design has proved the test of time. We have our new accelerator pumps in service in a wide variety of applications with ZERO failures of any kind.
Not a day goes by we don't get a call to the shop from someone who has purchased an aftermarket or over the counter rebuild kit and had the accelerator pump seal fail quickly.
I know those seals are too "soft" and swell up and fail in this new fuel, and why we use our own seal on all the pumps that we sell. Our pumps are also outfitted with custom wound springs to improve pump efficiency and engine performance. I attached a picture below of a brand new seal on a carb that was just "rebuilt" by the owner using a kit he bought on the Internet. The sellers advertised that the seal was good for modern fuel with ethanol.....it swelled up and rolled off the pump in less than a week!
We have not had a single failure to date, and are offering a lifetime Warranty of our pump seals. If for any reason it rips, tears, shrinks, swells or fails, we'll replace it free of charge forever!.......Cliff
PS: We also have accelerator pumps for the Rochester 2GC carburetors in both sizes.
