sarahcecelia, not the case so long as you install a good quality flow through type electric pump which does allow fuel to flow even when off. I have this type and when off, motor runs strong and doesn't die. Not saying I don't agree with your other points and also not saying you are wrong if the wrong type of electric pump is used. My main reason for using is in So Cal desert we get very hot days and my car has a major issue with vapor lock, this solved it for me.

did you remove the air cleaner to see if the carb is running over ? it has either a dirty needle and seat or a bad float, or not adjusted correctly, or to much fuel pump pressure, a good fuel pump has worked on these cars for the last 80 years, or more, all you need tight fuel lines and a good flex line, the flathead FORD V8 is a very easy starting engine, if started every few weeks, not sitting idle for long period of time, does not need all that fancy ad ons, why make a simple system difficult to diagnose when something does not work, my 2 cents 37Ragtopman driving my 37 since 1981

I repeat, your carburetor needs attention from a Stromberg carburetor specialist. It is not working correctly. Just because it was rebuilt, doesn't mean that it doesn't have problems. All rebuilders are not equal.

You absolutely have to leave an electric fuel pump ON ALWAYS; if you don't it will block the fuel flow and the motor will die ! I left it off on my forty, and it started to die coming home; and then died as I pulled off the road! I wondered "what is going on! " Well, after about 5 minutes I cranked it up and made it home ; (about 2 miles.) I don't remember how I learned that it must be on always, or it WILL BLOCK THE FUEL FLOW, but I think Randy Rundle (deceased), told me about it. AFTER THAT INCIDENT, I always left it in the ON POSITION, and never ever had that problem again!! LIVE and LEARN P.S. SOMETHING IS DRASTICLY WRONG IF YOU CAR FLOODS BEFORE IT STARTS!! TIMING MAYBE??? WEAK SPARK?? FLOAT LEVEL TOO HIGH??

I did want to mention that in regards to my electric fuel pump, I only leave it on long enough to prime the fuel to the mechanical pump, and then shut it off with a manual switch under the dash. Its not on all the time while driving and in doing this the car consistently fires right up and also doesn't struggle initially to stay on when cold starting. Best of luck.

So the carburetor is a new rebuild and you can't leave the choke out until it starts. It will flood before it starts. It reacts more like a Model A than a V8.

My dad had a new 1949 sedan. He told me how to use the choke for initial startups. He said- "Pull the choke all the way out, and when it starts, ease it back in slowly." I had a 1950 sedan several years (6) later, and that worked every time; even when it was 20 degrees out! Knowing when, and how, to use a choke properly is VERY IMPORTANT!!

It sounds like you need your carburetor rebuilt by a Stromberg specialist. I am sure someone on her can recommend a good one. It probably needs more than just a kit.

Be VERY careful adding an electric fuel pump when running a Stromberg 97 as float is easily bent. Better off priming manually and using auxiliary pump only after extended storage / lack of use.

My 51 had plenty of starting issues, would have to crank it for 5 minutes before I could get anything and messing with the choke did cause flooding quite often, very touchy. What solved it for me was getting rid of the points and switched to pertronix, put in an electric fuel pump to prime the fuel to the mechanical pump, she starts almost instantly now even in the colder months.
