Here is the question. Since I've had my stang back on the road a while I've noticed a problem that I don't remember having and I was curious if anyone else has a similar issue?

When I get gas the gas leacks back and drips onto the ground. I try to reposition the handle at different angles to stop it from leaking back. I don't even try to just put in the handle an walk away I have to hold the handle and force it in tight.

I'm thinking it might have something to do with the worn leaf springs in the rear which causes the rear end of the car to be lower.

Anyone have any imput or similar experiences?

 

Hey Doc....Yeah, if your Mustang is sitting butt down like mine used to do, then that could contribute to the problem. I hold the handle sideways and pull it about halfway out of the filler tube. I guess it's time you fought with that rusty bolt.

 

Someone really ought to design a different filler tube for our classics..

 

Well the old gas pumps had a nozzle about the same size as diesel pumps do now, then the unleaded switch caused the nozzle to get smaller so you couldnt put leaded gas in an unleaded car and muck up the cat converter.

If you have ever poured antifreeze from a jug you have noticed if you pour too fast with the handle in the upright position, it tends to splash around as air tries to get in the bottle and the liquid out. The same sort of thing is happening with the gas filler, there should be a vent tube on top of the fuel tank of later cars (like my 71) and also a vented baffle inside the filler to help diminish the gluping effect.

The nozzle is keeping air from getting inside the tank through the vents/baffles like it should. The airpressure builds up inside the tank and pushes the gas back out. Thats the WHY..

Heres the HOW...
Glen has it right, turn the handle sideways and find out what exact point the tank likes it held inside the fill tube, a bit of experimenting will lead you to what works best.

 

You could bend and weld a smaller tube from the base of the filler neck towards the top, to circulate that air and prevent the vacuum effect...

 

weld? on a fuel tank? can you say BOOM?

if you pulled the filler tube out and there wasnt one in it, then sure you could then weld on the tube, but not while conected to the tank... please dont do that...

 

I assumed you would understand me as meaning take it out, weld it, and re-fit it. Although I wouldn't necessarilly have to, since mine is brand new and empty...

This is the norm. Sideways and slow works for me, but manI'dlike be able to pull in andbuy that big nozzle104 stuff again.[sm=exactly.gif]

 

Yep, and at 35 cents a gallon. We chased women all night for a dollar.
