95 E150 fuel problem
95 ford e150 kicks the fuel pump off almost as soon as it starts... pouring gas in by gas can shows that it fills up to the neck... then slowly glug glugs into the tank if you listen from underneath.. dropped the filler tube and looked in the tube and it was clear.. ran a strong wire into the tank from the rubber hose and not sure if i felt anything. from my research the tank should not have anything blocking the 2 ports on the tank that the filler and vent hose is connect to. there is a plug on the rear of the tank by the tank that has a hard metal line and a short tube coming off it.. the rubber tube has what appears to be a vented cap on it. the hard line runs via the frame to a t-split up by the engine.. on side goes up to the engine and the other goes to a vapor canister..only a tube into the canister and nothing out only another vent like cap on the second port.
trying to sell the van and this is holding it up... thanks

this is a classic case of rendering the evaporative emissions systems inoperative....just leaving the cap off...so delicate in terms of back pressure to the charcoal canister...but alas you've flooded it...keep running until about half full and perhaps the check engine light will stop illuminating in your face~

your gas station pump knows when the tank is full....please stop at the first click...to put any more gas in is evaporative suicide~
I'd pull the vent cap off the vent hose to see if its clogged. Definitely sounds like a blockage.
thanks judge for not answering the question.. kind of hard to overfill the tank on 10.00 when its a 35 gallon tank. and as for a check engine light... never stated that i had one flashing... and as far as running the tank half full... right now it is about 1/35 full since i only put in a gallon via a gas can
thanks romero.. i take it that the rubber hose with the cap on it may be the one you speak of... look like a cap but when you pull it off the plug is like an x so perhaps air can escape thru it... other than that is there a way to vent the air out....

...jeez, rotten kids dropping rocks into the gas fill? needs to be examined~
no rocks in the filler tube... dropped the filler tubes and they are clear
had a thought that if i cannot get it to take gas that i slid a hose into the tank via the filler tube so that there would be an air gap between the hose and the filler tube.. thus putting gas into the tank via the hose and perhaps the gas vapor or air in the tank could then flow freely between the hose i inserted and the filler tube... any thought on that
or what would happen if i disconnected the rubber hose that come off of the hard line from the rear of the tank. it becomes rubber near the engine and splits in a T one to the engine and the other to the vapor canister.

you must try all of these things nkvan, a dual containment tube just doesn't seem practical~
Your roll over valve on the inlet of the tank could be faulty also

you know...you are filling....the air from your fill has to go somewhere...it is supposed to go into the charcoal canister....the air flow is blocked goin into or comin out of the canister...investigate these two vacuum tubes...think we've been down this alley before, but I was aggrivated and so were you...let's give it the old college try we can find that failure to exit into the ambient atmosphere---yes we can.~

Why don''t you post us a picture of the "roll over valve" beethoven?
