Street Demon accelerator pump nozzles

I agree that they should work. I believe they had that "anti-pullover" nozzle design originally on the early Holly Spreadbores. The design is suppose to keep fuel from being siphoned out of the squirters at high rpm. BUT, I thought that was the purpose of the needle that were located under the squirters. I suppose they had some design changes that replaced the needle or needed additional help. Don't know at what point if using the standard squirters might cause a problem with siphoning.
