Gas tank "leaks" under truck and won't fill

Hey all,
my first post here!

I recently bought a 1994 ranger, and I've had a lot of problems with it already, so your help is greatly appreciated.

I was filling up the tank yesterday, and the pump handles at this particular station aren't the best and sometimes flip off if you squeeze too hard, so I thought it was doing that, but apparently my tank was full and I see gas coming out from under the truck.

I don't suppose there is some kind of valve to let gas out so that it doesn't flow over your hand? Or does it necessarily mean I have a leak or crack or something?


The other reason I thought it couldn't be full was that I had put in $40 prior, which brought the tank to halfway to my surprise, and then the tank was "leaking" about $20 in, which leads me to believe a gauge sensor is wrong...
the meter said I was at 3/4 when I got back in.

Help :(

what year is the truck?

reason being today's gas is hard on the rubber filler necks on our trucks and the tend to rot out right above the gas tank. my 94 had that issue, i had to replace the fuel filler neck hose.

its rotten, time for it to be replaced..... as far as replacement the oem ones from ford are pricey and the ebay ones are just crapy.

i bought a ebay hose for 150bux when mine was leaking, about 2yrs later the new one i had bought from flea bay had started to crack. no leaks from it but started to crack.

oh BTW: sorry for askin for the year DERRRR it was in the first post lol.

You could climb underneath and peek around but honestly pulling the bed is your best option. Haveing pulled the bed you will have everything right there in front of you. It really not that hard to do. Just remove the taillights, tailgate, remove the six bolts in the bed, and the three bolts holding the filler neck to the bed and have a friend help you lift it off.

Don't buy a new neck.

Get a 2" Fernco rubber 90 degree elbow.
Piece of 2" galvinized pipe, and 1 1/2" pipe both about 3" long. Weld the 1.5" inside the 2" to created a reducing coupling.
Shove the elbow onto the gas tank. Takes a lot of force for this.
Cut the filler neck but not the inside tube. Shove the pipe inside the neck, clamp it and then clamp the elbow to the pipe. Clamp everything tight.

I did this a year ago and it's held up great!
Just takes a little fooling around, it's gotta be the right length or the filler neck will be too long and will create a "trap" and you won't be able to fill up your tank.

Total cost, about $15

If it's any help, I looked at it more closely when filling up today to try it, and it was leaking before it was full and it was running down the side of the tank...
