Re: Runs for about 10 minutes and the just quits
No,No,No. Do not vacuum the tank. The fumes will ignite in the vacuum and explode and burn. Also don't assume without verifying that the fuel is starving. see#13.

Re: Runs for about 10 minutes and the just quits
The same goes for using a vacuum to clean up the old gasket material when replacing the gas gauge components. Resist the temptation to use the vacuum or you may likely suck gas fumes into the vacuum where the sparking brushes in the vacuum motor will light things off.

Re: Runs for about 10 minutes and the just quits
A guy I knew hocked up a hose to the exhaust of his modern car, ran it into the tank and the welded it. No oxygen so no explosion.
I would not try it but he did. |

Re: Runs for about 10 minutes and the just quits
I had an unusual one about 12 years ago. Same issue as you described. Turned out the add on pipe on top of the shutoff inside the tank had come loose and fall off. It was rolling around in the tank as you drove. It would eventually end up just over the hole that the gasoline flows into at the center bottom of the tank. The piece of pipe would then, in turn, block the flow of fuel down the line to the shutoff and carb. If you sat and waited for about 5 minutes, the flow of gas got around the blockage and the car would run for another 5 to 10 minutes and then would repeat the situation once again. A long pair of tweezers grabbed the culprit out and never had a problem since.

Re: Runs for about 10 minutes and the just quits
Does it run and stop in 10 mins NOT being driven?
Easy elimination check whether fuel or spark. |

Re: Runs for about 10 minutes and the just quits
I got interested in this thread because I also have a '28 RPU and the exact same thing happened to me some time ago. It turned out that the gas cap vent was clogged as others have mentioned.
The other thing that interested me were the gas tank postings. Back in 1960 when I was stationed in the army in southwest Germany I had a 10 year old Mercedes 170S. Two of my friends and I had leave and decided to drive to Paris in it. We didn't get far when it started missing badly. We pulled in to a Mercedes dealer in Saarbrücken and they found that there were a lot of leaves in the gas tank. They fished a lot of them out so I paid them and we continued on. We only got about 50 km or so when the problem continued. We stopped in an auto repair shop in a little French town and my buddy, who spoke some French, explained the problem to the mechanic. He put the car on his lift and then drained the gas. Next he took a cutting tool and cut a hole in the tank. Lots of leaves came out which lead me to believe that I had been vandalized. After that he welded a patch on it with an acetylene torch. All three of us backed up when he did this but nothing bad happened. I paid him and we went on to Paris and had a good time there (another story). Robert |

Re: Runs for about 10 minutes and the just quits
In my case, it's the needle valve, sticks occasionally. I carry a small hammer and just tap the side of the carb and it always starts after that. I'll take it out at some point this winter and use carb cleaner and a Q-tip....

Re: Runs for about 10 minutes and the just quits
Its been a few days and will be interesting to hear what he found.
It should be fairly easy. When it quits, check for secondary spark ASAP. If there is spark, check for a good solid fuel flow. |

Re: Runs for about 10 minutes and the just quits
You should try to deal with a tank that LITTLE KIDS added Berries from a Chinaberry Tree +&%^%$$%#@--- Or a roaming GUM WRAPPER, or a Handi-Wipe, disintegrating in the tank. Or when Little Kids topped off the tank, with the GREEN Garden Hose!!!!

Re: Runs for about 10 minutes and the just quits
Oh I hope not! I think it was something simple! And he got it going, he’s probably been on a nice long drive.
