1 Most crate engines, including the popular 602 and 604 Chevrolets, come with everything between the intake manifold and the oil pan, but lack a lot of necessary components to get it running. Last issue we installed the flywheel, starter, and bellhousing from Quarter Master. This time around we’re starting on the other end with the fuel system. The first step is to install the fuel pump pushrod. Make sure to use plenty of assembly lube on both ends. Some lube on the sides of the pushrod also helps hold it in place until you can get the fuel pump bolted up.
