Should I be feeling more power?

Yes, it should perform better with your existing layout.

Loose the secondary electric fuel pump, it is causing restriction to the amount of fuel the manual on the engine fuel pump can pull.

Here is a "Visual" for you:

Think about it, the factory fuel line from the tank is 5/16" in diameter.

When you add in an electric inline fuel pump and pre filter, it is literally cutting the fuel line flow down to 1/8" diameter, starving the engine for fuel when it needs to pull.

It will run and perform just fine with the manual engine mount fuel pump pulling the fuel from the tank.

The secondary electric fuel pump idea is where you let your car sit for long periods of time and the fuel evaporates out of the carb.

Drive the car more often, simple is good.

Thanks for the pics and information, George. I don’t follow you on this because I’m a rock skull! Lol.

What do I need to do to “lose” the secondary fuel pump? The seller had a switch put in the car that activates the pump. What would happen if I flipped that switch to on? Just curious.

Here’s the explanation of why the seller installed that switch. This is an excerpt from the salesman (car was sold on consignment through Classic Auto Mall) who sold me the car. He relayed the information from the seller to me via text.

“As for the second fuel pump switch, that was a safety precaution after I scrapped out on him back in 2007. Left him stranded on the turnpike, so he installed a secondary one for backup. Said he hasn't had any issues with the mechanically Holley pump since 2007 incident”

It was the only “red flag” I saw when I purchased the car. It’s such a nice car and was very well maintained.

You’re saying that if I bypass or remove the secondary fuel pump, there will be a noticeable difference in power/ performance?

Thanks again for the insight on this!
