How To Install a Mechanical Fuel Pump on a Small-Block Chevy

In this video, I also cover a lot of projects that need to be taken care of before I can fire up the 81 Corvette so I can start the much-needed and it seems long overdue coolant system flush.

Frankly, I was surprised and somewhat disappointed to see so much corrosion in the cooling system, and that worries me enough to do a couple of long (I am talking an hour-plus) flushes.

I even looked for the two block drain plugs, but it was too much of a job to remove them because they are hidden behind the spark plug wire shields.

I also installed the fuel pump and the correct fuel hoses. After seeing the kinked main fuel line, I was surprised the car ran at all.

By the way, this procedure applies to many GM vehicles, including GMC and Chevy trucks, Cadillac, Buick, Oldsmobile, and Pontiac, so owners of other vehicles made by General Motors may benefit from the information in this video, especially when it relates to the fuel pump.

As you will also see, I managed to fix or address a few other smaller items such as the ECM coolant sensor. The original one was a disaster and I am confident the new one will work properly even though it's a newer style.

Anyway, I don't want to spoil all the fun and the table of contents below will show you every chapter along with the appropriate time-stamps in case you need to watch a specific segment.

I hope you find this video helpful.

Thank you for watching! 🙂👍🏻

Working on a vehicle can be dangerous. If you're not confident, qualified, or lack the tools to do the job correctly and safely, hire a mechanic.
