I recently needed to replace the fuel pump on a 1970 Dodge Monaco with a 383 engine.
The Dodge 383 was a popular engine in many vehicles, including the B-Body Mopar muscle cars Charger, Roadrunner, and Challenger.
Having replaced fuel pumps many times in the past, I ordered a new unit and started to install it.
I found out there was a push-rod that had slid down, stopping the new unit from going into place.
If the push-rod falls down it will need to be pushed back up into place.
If it does not stay up in place, grease can be used to help it stay while you insert the new fuel pump.
I ended up removing the alternator to have more room to reach the 2 bolts and the push-rod easier.
Replacing the fuel pump can be done without removing the alternator but it makes the job much easier.

Replacing the fuel pump on a Dodge 383 is easy enough, with two bolts and gas lines needing to be removed.
The location is the difficult part with the pump below the alternator.
If the engine is out of the vehicle, it will be easy to replace.
I removed the alternator, but it is not a requirement.
The push-rod may come down and need to be pushed back up into place.
Use some grease if the push-rod will not stay up to help it stick.
