This is Sierra's fuel pump kit, number 18-7817, listed for MerCruiser engines against the number 21-857005A. It replaces the Chrysler/Mercury numbers 21-42990A7 and 21-857005A1, along with the A8, A9 and A10 versions. Nothing further about construction or ignition protection is stated, so treat the cross-reference numbers as the way to confirm it is the right kit for your pump.
Our take
The long list of Chrysler/Mercury numbers this kit replaces, from 21-42990A7 through 21-857005A1, is its strength: you can match it against several Mercury part numbers on an old pump. Nothing is stated about construction or ignition protection, so those points stay unconfirmed.
