I just added an electric pump near the gas tank. The pump will run 4 to 7 psi. The pump removes the vapor lock problem. What does 7 psi do to the carb? Any harm if I leave it on? It's 85 out today and a hill climb sets off the vapor lock problem. Kick the pump on and the vapor lock is gone in a very short distance, say 60 yds. Our fuel just got the 10% ethanol added this winter is a problem, it's 85 out today.

I wouldn't be surprised if we all have to go to electric fuel pumps to overcome the vapor lock problem caused by this newer formulation of gasoline in our older, carbureted vehicles. I know of two Corvair owners (dual carbs, and it gets pretty hot around them and around the fuel lines) that have problems with the vapor lock.

Wow, I'm really just a little embarassed to even ask, but what are the symptoms of vapor lock? I drove about 3 miles to a gas station to get gas for the first time after restoration, and after filling up and driving about another mile, the engine sputtered, gagged, stopped and started, and finally stopped in about 1/4 mile. Towed it home (which took about 15 minutes) and after it sat for about another 10 minutes, it started right up and I drove it into its' space. I have started it and let it idle for up to 30 minutes about 6 times since and had no problem with it running at an idle. I don't remember the temp that day, but here in West Texas, I wasn't wearing a jacket, so it must have been just above 70 or so. A nice day, but not over 80.

Sounds like vapor lock-the under hood temp went up when you shut it off to fuel.Boiled the gas in the line,and you ran it till the carb emptied.

search "return line" and "vapor lock" on this site.

Jeff seems annoyed that people don't use the "Search" feature on this forum before asking (what they don't realize is) a common question around here. ;)

Thanks guys. I am convinced that that was my problem now. And, I may have cured it. While working on the headlights and parking lights, I discovered that the body shop had not removed cardboard from behind the grills when they painted it. No air getting to the radiator and engine compartment. So the heat factor must have been the cause.

I'm guilty of not using the search tab at all times. Sometimes using search seems like going to a library for 8 hours. It's easier to post the question in a new post and get current info. The search info does yield more info. Tank cleaning is another popular topic and I usually refer to "search" tab for "Draino".....BRAD

Welcome to the wonderful world of vapor lock. I had many problems with it on my trip to South Bend last summer. I believe I will be installing an electric fual pump this spring.

I well remember when I was only about 5 years old traveling from Arkansas to Dalhart, Texas. My parents had a 1950 Champion that ran fine down the highway, but several times in town in the summer heat the car would just shut off. My dad would jump out, open the hood and pour some of the water from our cooler over the fuel lines and the engine would restart. A bit of a nuisance, but not too uncommon.

How is that being annoyed?
Did you see a pithy comment attached to my follow up post?
People are here to learn and share the Studebaker experience.
People have taken a lot of their time and years of knowledge to share that information by writing meaningful replies to legitimate questions.
It is kind of a disservice to those efforts past to just discard it and ask the same question(s) again and again and again.
It is actually kind of lazy. But that isn't something that happens here now, is it?;)
As a knowledge resource, this is an awesome place.
So is the library.
Use the search function to find out what someone has already written.
But I will also provide this additional duplication of sought knowledge when a totally repetitive question a/o duplicate thread pops up. Totally free of charge, just to help the knowledge seeker.
(anxiously awaiting the next tire size and oil question;))

Maybe the search and FAQ buttons could be made bigger for newbies to find. (or people who don't know about it!):)

DDEPNHOCK, thanks for the links. I didn't think it was at all negative. I DO know about the search and have used it. My biggest problem with it is there is so much more off-topic comments than technical info. Which is something I absolutley love about this site. So, ... do I search and read a lot of other stuff, or ask and get an immediate answer. Tough situation to narrow down to a single answer in my mind.

So, thanks for the help, and I'll keep on 'searching', and I'll keep on reading, learning, and enjoying.

Don't care about the size of the buttons, but IMHO a glossary would be awesome.

Vapor lock, sometimes is not vapor lock. And you probably won't find this in the "search". I have had more than one occasion where what I initally thought was vapor lock was in fact a bad condensor. Don't hang up -- hear me out. I have been working on and restoring cars for years, and the first time this happened to me, I spent mega bucks and many hours trying to cure vapor lock. It always seems that when you stop a vehicle, and start again in a short period of time is when vapor lock occurs. This happens a lot with old cars. Short trips and stopping and starting. A condensor can have moisture saturation and do the same thing. So, if you have a reoccuring problem., Take a spare condensor and try it. I have never had vapor lock on a car with electronic ignition, but I have had it on one with a electric fuel pump. Just a tid-bit.

I do not mean to offend anyone when I post a topic.. It seems to me if a subject (vapor lock in this case) is so well explored and of no interest, why even read or respond to such a question let alone read it. Any time a subject is on the chat it will open the way up for any new thoughts and new information.

An excellent point!
Many times I have had to stop myself and remember one of my first mechanical mentors reminders...
He would always remind me to keep it simple.
It is a simple machine.
It still takes fuel, compression, and spark.
Make sure each one is right, and you will only have one to fix.
Still good advice.
I can wander down the wrong branch as easily as the next guy.
Just don't wander too far;)

I would like to thank any and all long-term posters who had to read posts they've seen before and answered anyway. Very politely I would say that I just didn't get around to reading the archives and saw a post that covered a problem I thought I 'might' have had, and due to the knowledge of others, discovered that was my problem and that it had been cured without me realizing it. I also want to thank all of you for loving your Studebakers maybe as much as I love mine. It and I were born together, grew up together, and are still together. It is wonderful to read every single thing ya'll write about them.

I've never had a problem with vapor lock in my Stude in the 17 years I've owned it.
Years ago (in the '50s) a common treatment for vapor lock was to add a can of Crisy Dry Gas to the tank and that usually prevented vapor lock.
You may not need to install an electric fuel pump.

Sorry about that, Jeff. So, I was wrong in that it only "seemed" to me that you were annoyed. That's what I get for assuming something based on the fact that you had no comments at all alongside your links, whether pithy or pleasant.

I know we are supposed to be free to share our opinions (to a degree) on this forum, but I'll try to keep mine to myself from now on. It's like email messages...there's no way to convey how you really mean to express yourself - so much is left to the reader's interpretation. Again, like Napoleon Dynamite would say: "Sorry!"
