ok...i know some of you have been dealin with this for a while and either just deal with it, bite ur lip, or you've found the loop hole. when i try to fill my 67 coupe with the fold down cap i have to pump the fuel slow cuz itll shut the pump off or poor the gas all over my shoes.......i was wondering if there is a cure for this?

 

My 65 does the same thing. My friends' classic Stangs do this also. I think they are all like this. At least thats what I hear.

 

Modern gas pump nozzles are lame, half the size of the ones the car was designed for. Hold the handle up, so the tip is in the middle of the pipe.

 

I've got it down to a science. Hold the handle almost upside-down at about 2 o'clock, then push it towards the car, levering the nozzle towards the bottom of the fill neck. On some pumps that flow really well (or when there's no other cars at the station), you may have to fill really slowly.

 

Upside down always worked for me, you gotta listen to it too, the sound changes before it shoots gas all over you. Sounds like a tiny train coming. Be happy the fill isnt behind the license plate, that is a PITA, but at least the nozzle fits in there sideways and seems to fill ok. All my old cars are like that, except the Mustang.

 

ive had several people come up to me while im crouching down behind my car holding the nossle filling up and say things like "that looks like a pain in the ***" to which i usually respond "you think?" terrible filler neck is terrible. i am considering removing the filler neck all together and just popping the trunk to fill it up. at least that way i wont have to sit on my knees for 5 minutes holding the nossle in an awkward position.

 

This is what I do. I rarely have trouble pumping gas this way.

 

Here's what I have done to hopefully stop the overflow of gas from the gascap when being filled. Note! I am in the process of putting the car back together so I don't know for sure if this will work. I got a late model filler neck with the small trap door in it from the junkyard, cut it apart and removed just the trap door portion. I then cut my '70 filler neck in half, welded in the trap door and then welded it back together in the same configuration. The length of the '70 filler neck probably only changed a 1/16" in length. The end product looks like a stock filler neck, bolts up exactly as stock, still uses the stock gas cap but has the trap door installed. This modification can easily be done, just undue the rubber hose connecting the tank to the filler neck and the 5 screws holding the filler tube/neck to the body. You obviously don't have to take out the tank. I also ran a venting tube from just under the trap door to down into the tank following the top of the gas tank filler neck. I'm not sure that this was necessary but that's the way it was on the donor car. I hope the trap door and its incorporated restriction will cause the gas filler hose to shut off when it senses fuel backing up to the trap door (check valve) just like a late model car. I should be able to fill up by just putting the nozzle into the filler neck and not having to hold it in, or sideways or upside down. Only time will tell. Here's some pics.
The first pic is the donor filler tube. The second pic is of just the trap door portion that I cut out of the donor. The third pic is the completed filler neck for my '70 with the trap door installed.

 

Hopefully that'll work. I had thought about something like this while doing our car but never got around to it.

Honestly though.. I really don't have much of an issue at the pumps. Insert gas handle then turn it slightly to either 10 or 2 o'clock then slowly start to fill. Once I know I have the correct angle I can squeeze the handle more to almost full pressure. I have a microfiber cloth I always have in hand just in case but rare use it.

New Jersey is a Full Service state which means were not really allowed to pump our own gas! That said I've only had 1 attendant give me a problem.. I politely told him and drove across the street where they didn't have any issues with me filling the stang myself.

 

Its a full service state. I don't understand that one.
