One is the original Chrysler mechanical fuel pump, with actuating rod.
The other is a Huco electric pump, which was used as a starting/priming pump. Note that although this pump will supply enough fuel for starting, idling and low-power running, it is unlikely to produce enough sustained flow for a 383 at full power. I used it for carb priming only, and then switched it off once the engine was running and the mechanical pump was operating.
£10 for the mechanical pump, and £5 for the Huco - both plus postage.
