64 american wagon hard start after warm up

Recently purchased a 1964 rambler American 330 wagon,32000 original miles, runs great after being parked for 10 minutes it is so hard to start, I suspect vapor lock,I was considering installing a Rochester 2g on the Lhead engine, someone recommended an electric fuel pump for the problem. anone have any Ideas??

I understand you have the flathead.

The flathead has the fuel line between the fuel pump and carburetor running very close to the exhaust manifold, if that has been bent out of position, or even in it's stock placement, it's prone to vapor lock in that section of fuel line.

Move that fuel line away from the exhaust manifold, and insulate it.

Personally after some almost 60 years of fixing and driving my own cars and the last 15 of them living where 1/3 of the year it is over 100 degrees I can pretty much say I have had one verified case of vapor lock and that was when I was using a cheap cut rate source of alcohol diluted gasoline.  And that was on a port injected 3.8 Liter Oldsmobile.
So I would be pretty sure vapor lock is about the last problem you would have.
Doesn't that engine have a carburetor that bolts into a plate that is part of the cylinder head?  I suspect that possibly there is some perculation going on with the carburetor sitting where ever it sits if that is the case.  I'd check to see if the carburetor is properly mounted and that the fuel pump is actually any good.  And also see if the rubber hose that connects the gas tank to the fuel line is not full of cracks and such and sucking air through it.
But then again.
I dunno, it just seems to me that if I don't see vapor lock problems at 110 degrees in Phoenix, I would not expect to see many of them in PA.

Simply using a rubber fuel line in place of the metal line will most often cure a vapor lock problem. The rubber doesn't heat up and boil fuel.

I never had vapor lock when in Idaho, but drove the car I had at the time to Ohio one year and it suddenly started vapor locking. This was in the early 90s, before alcohol in fuel. Still, fuel blends differ across the country, and altitude and humidity also have an affect. I got frustrated the second time I stopped for fuel and had to push the car out of the way and wait 25-30 minutes to drive off. Saw a hardware store across the street, went over for a mini tubing cutter, rubber fuel line, and a couple clamps. Was driving off in a few and never had the problem again! I drove that car six years before having that vapor lock problem in OH... very annoying!

OK so I'll give it to you in a nut shell, this weekend installed an electric fuel pump and the Rochester 2g carb on my little wagon, boy did it wake up that L6 engine.
