Gas spills out from filler.....

I have a 63 ranchero and the gas spits and spills out of where you fill up the gas. I bought a new gas cap thinking that might help, but it didn't. Anyone have any ideas about what to do?

Thanks

Don't fill so high. Clean the vent tube and get a proper fitting NON VENTED cap.

Re: Gas spills out from filler.....

Few years ago, had same problem at the filling station with my 1960. But solution then was not to fill too high (no longer a problem due to cost) and then feed in the gasoline more slowly. The Ranchero and the S/W have abrupt bends at the neck, now making for slower filling to top off.

My solution, and may not be same as others.

Re: Gas spills out from filler.....

You two are fixing a filling issue. He only said it spills out where he fills it, not when he fills it, even with a new cap. I told him he needs a Non Vented cap that fit's snugly, then the fuel will stay inside the tank.

The tanks in 60-63 were vented, and the cap was not.

Thanks for the replies. I will try the gas cap. I thought there was going to be something more labor intensive than a gas cap.

Re: Gas spills out from filler.....

Before you get a non vented cap make sure you have a vent. I don't think Rancheros have a vent like some of the cars do . I know there is no vent on my 65 ..

Re: Gas spills out from filler.....

Rancheros and probably wagons and Sed Deliv's had a vent up to about 63 or 64. Then Ford discontinued the vent. The sedans and converts still had a vent though. That's why 65's need a vented cap. Which is part of the reason most have gas stains down the side. From gas leaking on right turns and spitting back when trying to fill. The other reason is because the filler is too low on the fender.

The solution is to relocate the gas filler up higher on the fender, add a vent to the filler neck and use a non-vented cap. Notice how later Falcons and Rancheros had the filler up higher in the fender? They also don't have the stains down the side.

Re: Gas spills out from filler.....

I'm pretty sure all falcons and chero's are tank vented to late 63.

Re: Gas spills out from filler.....

If you look at the tank you will see the filler is at the bottom of the tank and not at the top like most tanks.

I know all of my early ones and my friend's are too. I think they use a S/W tank and filler neck. They have a secondary line on side to act as a vent too.

The new cars have a "trap door" flap on it that is spring loaded on the filler neck. It may help to keep the fuel from coming out. If the filler tube assembly was taken out of the Falcon & a correct inside diameter filler pipe with the "door" from a donor car be welded /mated into the Falcon pipe, would this solve the problem? OF COUSE A WELDER SHOULD DO THIS TO AVOID THE RISK OF EXPLOSION. Or a donor filler pipe from a late model car could be used to fit the Falcon?? Thoughts on this guys. I've been thinking of this solution, but havn't done the research on wht car or efforts needed etc........

I doubt adding the trap door will effect the spitting back much. But I think Ranchero65 is onto something. The inlet fitting on a Ranchero is at the bottom of the tank instead of the top as most tanks are. Air gets trapped in the top of the tank as you fill which restricts fuel flowing into the tank at the rate of the nozzle. Adding a vent of decent size to the top of the tank and connecting to the top of the fill neck would allow the trapped air to get out easier and might inmprove the spit back. As far as gas down the side while turning , I think the only real solution there is to raise the filler up higher. and using a a non-vented cap. Plus adding a vent to the fill neck as well.
