My Cosworth has no throttle response in mid-range rpms. I have to rev to 4000rpm for the car to drive. It starts and idles fine. Ideas?

John, thanks so much for the advice. I contacted Tri-Starr yesterday on the recommendation of other CVOA members. I will definitely send them the sending unit. They're not accepting new work until mid-July. My local mechanic did a temporary fix so the car is running again. The tubing lines were badly rusted and had a 1.5 inch gap from a rusted out area (it's amazing the car started at all prior to the temporary fix). I'm going to send the tank out as well for internal rust remediation and coating. I also replaced both fuel pumps because both were filled with rust particles. Fortunately I already had replacements for both pumps.
