Why do you need an electric fuel pump? Is that what you use for an under bed gas tank? It is NONE of my business, but it made me curious. Sounds like it would complicate things to me. That's just me & I'm learning too.
Whatever you end up going with, you can just make the mechanical fuel pump a "dummy" and leave it where it is and solve the 'block off the pump chamber' question. Take the guts out of it, reseal it, & put it back.
If you are going with an electric fuel pump, you can just run the fuel line from it to the carburetor. The mechanical one is out of the equation. Though I did read a post a few months ago (or saw an add?) about an electric/mechanical pump combination. I do remember the writer was pleased at having the mechanical pump as a backup.
Lastly, I had a line going from a vacuum can on the distributor to the carb, too. What is this?
The line from the vacuum advance on the distributor to the carb is called the vacuum advance line. It helps out ignition timing. Here's what the internet says
about it because I can't explain it to you myself.
I hope this helps, and I'll be following this to find out about the electric pump.
