This topic has been covered before, but it seems that Ford covered it: FORD TECHNICAL SERVICE BULLETIN BULLETIN NUMBER 104 MARCH 5, 1976 Under Maverick/Comet it has listed:1975-76 Slow Fuel Tank Fill and/or Fuel Spitback at the Fuel Tank Filler Pipe Does anybody have this bulletin? It would be nice to see how Ford suggested fixing this. One could buy the bulletin here: http://cgi.ebay.com/ebaymotors/ws/e...0301209802&viewitem=&sspagename=STRK:MEWAX:IT
I Googled it and it says it's covered in an "article 1355" which is a replacement fuel filler neck. God knows what part # it is,cause that was all I could find. I'm sure there are a lot of these on cars in junkyards. Mine does this too,and I've just gotten used to it being slow. Mines a 74,though,so I don't even know if the newer pipe would fit my car.
Funny how that bulletin only goes to 1976. My '77 Maverick always blows back fuel if I fill it up too fast or too full. Apparently whatever the problem was it continued for one more year. I too would like to know how FORD went about fixing this problem.
I think that the main problem now is that newer gas pumps run a lot faster than the ones in the 70s. I have only been able to use them at about half-speed.
My filler tube is empty -- no vent tube and no unleaded fuel restriction -- and it doesn't splash back. But, I don't run the pump full speed. Always run it at about .1 gal/sec on any car. Works for me.
I should trailer the disassembled Comet over to the local dealership... "Hey guys, I got this bulletin in the mail... could you knock it out real quick? Im gonna go grab a coffee."
Yeah, but who wants to spend half an hour at the pump, unless there is a cute chick at the pump next to you... I used to keep the key ON an watch the fuel gauge through the back window, but the new tachometer is in the way. Now, I just pump until it clicks, or most likely, splashes back, then feed it slow until I see it gurgling just at the turn down.
In B.C I have never had a problem...but everytime I go south of the border..tidal wave! I can only put fuel in by barely squeezin' and even then it will click off a few times. Your pumps are waaay faster..
