Found the running board paint bubbled the other day after fill up the night before on my 1950 3100 ( Tank is behind the seat). Outer most channel directly under fill cap had 4" long bubble and splitt open ( nothing on the fill neck or the side of the cab). I think it happened because of the heat expanding the gas in the tank. I have been carefull not to overfill ( I listen to the fill and stop early not allowing the pump handle to stop the flow). I have had the running board repainted (They are base coat and clear) but was wondering if this era trucks had problems like this.

It is very common. A search will find several threads.

My truck does the same thing overfilling or parking on an angle for that side on a full tank is not good.

Hi, Tom , I had the same problem with my 49, so now I only try to put in 3/4"s of a tank if I am not driving more than 30 miles after fill up.

Mine did it once sitting out in a blacktop lot on a hot day.

Thanks for the feed back. I just thought that the filler tube was vented and should have run out. Not thru the cap area. I am just glad that it did not run down the side of the cab because my painter said it would be very difficult to repaint. Show quality paint and can't get between cab and box without box removal. Well I will have to watch it very carefully on fill-ups. And be glad the running board looks as great as it does.

Never fill it completely full unless you're going on a long trip and driving it right away.

Do not have that problem in a 48, tank under bed like all the new trucks.

Sometimes good ideas go in circles... wink

Another thing I have trouble with is making a left hand turn with even 3/4 full tank - it tends to slosh out !

britcon : take yer gas cap to the hardware store, go to the plumbing section and look for the rubber o-rings. Find one that fits, just inside the gas cap. This will make it snug down on the filler neck, should prevent the slopping over.
