🔍 Key Concepts

• Rotary distributor vs in‑line fuel injection pumps – how their shapes and layouts differ • What a distributor head with multiple outlet ports** usually looks like on a rotary pump • The difference between a fuel injection pump and a single injector nozzle assembly

💭 Think About

• Look at which figure shows one compact pump body that could both pressurize and distribute fuel to several cylinders from a single rotating element. • Decide which figures are clearly not pumps at all, but rather individual injectors or other fuel‑system components. • Compare the long, rectangular �in‑line� style pump with the more compact, rounded "rotary" style pump and ask which one better fits the description of a rotary plunger distributor type pump.

✅ Before You Answer

• Eliminate any figure that is just a single injector nozzle, not a multi‑cylinder pump. • Identify which unit has a central rotary head with several outlet fittings arranged around it – a hallmark of a rotary distributor pump. • Confirm that your choice is a self‑contained rotary pump assembly, not an in‑line multi‑element pump housing.
