This Holley fuel pump is replacing the identical Holley fuel pump that installed in1985 on a GMC big block 427 flatbed dump truck. The fuel pump was still working, however under prolonged full throttle, full load operations it would starve the engine for fuel. 35 years of service I would say that's a good product review. Hopefully, I will still be here when it needs to be replaced 35 years from now. Paul

Building a very nice 1966 El Camino 396 4/ speed with buckets seats. This will be a restoration with some mods to make it look sharp and be better than original.
