Check to make sure your Gas Cap is vented. If it is not vented you will have problems.

an unvented cap will cause a vacuum in the tank by pulling liquid out while no air is replacing it.
I don't know how a tank could become pressurized except sitting out in the sun

Sorry about the thread goof. A lag between my computer and this site, I guess. Hopefully this is better.
Hey all
I got my starter problem figured out. The piece that holds the spring near the armature wasn't there and so I replaced it. Works really well now.
I then decided to fire up the engine and much to my disgust I discovered a gas leak at the pump. Rebuild time ? I decided to release the pressure on the line so I removed the gas cap and to my surprise there was a lot of air pressure. Is this normal. I realize there should be some pressure but this seemed to be alot.
If this is not normal, what would cause excessive pressure like this.
Thanks again,
Cliff

I tried to do it earlier but I had to leave to go and play hockey. Summer hockey.... nothing like it. Go to the rink in shorts and sandals, get all dressed up to play on frozen water and then change back to critique our game at the bar.
Now to qualify this for the thread.
A vacuum in the tank is a better way of describing what happened as opposed to pressurized.

A vacuum I can understand. Check the gas cap for a vent hole somewhere on the cap. If you don't have one change caps or make one.

Had a similar problem on my 28.
Ran an old cap for about 25 years, more loose than vented.
Fitted as nice new cap, next day gas has flooded through the vac tank and the engine bay, right accross the shed floor.
Seemed that a rise in temp with a non vented cap or running the engine and the heat from the exhausst pipe underneath made a nice little pressurised system.
Simple fix by drilling a 1/8 inch hole in the cap, and fitted a pop rivot. The body of the rivot being lower than the underside of the cap, eliminates any chance of a fuel splash.
No problems since
Regards
Ray
Some say "Street is neat". I prefer "1928 is great" I have documented my 45 years with a 1928 Chev Tourer, from 1973 to 2018, and regulary add other items that I hope are of interest to others. Your comments are most welcome.The story of the Red Chev can be viewed at http://my28chev.blogspot.com/

Hey
I checked the vent hole in the cap and yes it was plugged. Haven't had a chance to fire up the car again. Hopefully this will solve my latest issue.
The next minor inconvenience is I can't get the right front brake drum on as, it appears, it won't fit over the brake shoes that have been religned. Same thickness as the others. Did I reassemble it wrong somehow ? Any thoughts!
thanks,
Cliff
