Modified Syringe. Hi guys(and girls), Does anyone remember a system using the above,between 12 to 15 years ago,a description of the above,whereby a modified "injector" was utilized to ensure that not only did an I.C engine use it;s entire fuel supply,but that the device also served as a one way valve preventing fuel drawn forwards from returning to the tank?I think that it appeared on the "Reader's Tips" page.
