kramttocs Posted August 21, 2019 Share Posted August 21, 2019 Hi Gary, The garagemahal is such a great resource - thanks! According to those diagrams, part numbers are 9034 in both cases, but clearly each filler neck is a different shape - does that make sense? LD The "9034" is the generic part number. And every filler neck, officially Pipe Assy (Fuel Tank Filler), for every Ford vehicle ever built anywhere in the world will have its filler neck listed as a 9034. But, it is the prefix and suffix that are needed to differentiate between, say, a 1950 Ford sedan built in the US and a 1990 Ford truck built in Europe. If you go to Fuel Systems/Fuel System Part Numbers/Fuel Filler Pipes you'll see that the Bullnose ones are something like E0TZ 9034-C. The "E" in the prefix means the 1980 decade, and the "0" means the first year of the decade. In other words, that part was engineered and/or first used in 1980. And the "C" means it isn't A nor B nor D nor...., with each change in letter of the suffix meaning the part is different. Perhaps it is a slight revision and will fit and/or work, or perhaps it is a part that doesn't even look the same and certainly won't fit. And we don't have any way of knowing that by just looking at the catalog. As for the later ones, I've read that the later fuel filler systems will allow the gas to be pumped in at a much higher rate. And since Big Blue is both thirsty and shy about allowing gas to be pumped in, I need to explore what the differences are. But, at this point I can't tell you if it is just the filler neck or the hoses, or the combo. Perhaps someone else can enlighten us? I've added it to my Junkyard Wunderlist so will pick one up if still needed then. I've never looked at a next gen one so I am afraid I am no help there. I just recall someone talking about it and gaining a 'better cap' and improved flow like Gary mentioned. One thing I did notice when I was pulling them at the jy was that some had the flap in them and some didn't. My 86 and the one I pulled from an 86 didn't but some of the others (I know one was an 82) did have the flapper. Just found it interesting.

kramttocs Posted August 31, 2019 Share Posted August 31, 2019 Weather and time permitting I may run to the jy tomorrow morning. Are you still needing this? If so, does yours have the flapper? I don't know if they all had flappers except the 460 or not but that's the pattern I've seen. Link to comment Share on other sites More sharing options...
