Summit Racing™ Ultra Light fuel pump pushrods are some of the lightest in the industry—designed to keep your engine running and fuel pumping at high RPM. They weigh in at 60 gms vs 144 gms for the stock unit. This is achieved by machining a piece of aircraft-grade billet aluminum bar stock and inserting bronze tips in each end. They work with all flat tappet and roller camshaft cores; and have been tested in Circle Track and drag race engines with no signs of wear or fatigue.
