Len69Coupe 33 Report post Posted October 13, 2019 So I'm doing my mock up for my EFI system. When I install the tank the fuel tank filler tube doesn't line up. This is a Tanks Inc. EFI fuel tank kit. So either the angle on the taillight panel that I replaced is wrong or the tank spout is in the wrong location. I have the tank pulled as far to the rear as possible. I thought maybe I could cut the filler tube shorter since the rubber adapter is flexible, but I'm not sure if that would correct this or not. I thought I read that the 70 filler tube is at less of an angle then the 69. Can anyone confirm? Quote Share this post Link to post Share on other sites
det0326 179 Report post Posted October 13, 2019 The tanks inc tank is a larger capacity which will put the filler tube at a different angle. Your remedy of cutting the tube is what I did, and it worked perfect. However there is a after market tube that will work, that was made to correct this issue. I have seen them on ebay before .

Len69Coupe 33 Report post Posted October 14, 2019 Thanks for the help det0326. I'll cut it and see how it looks. If not I'll see if I can find the aftermarket tube. Quote Share this post Link to post Share on other sites

As far as I remember, 69 and 70 filler tubes are NOT the same; 70 has the bigger tank so the filler matches to bigger tank. 1 RPM reacted to this Quote Share this post Link to post Share on other sites
stangs-R-me 120 Report post Posted October 22, 2019 YES, 1969 & 1970 Necks are different … they are bent slightly different and the '70 is slightly shorter. Whether it is all due to 1969 having a 20 gallon & 1970 having a taller 22 gallon or if the different taillight panels are part of it as well I don't yet know. Since I sell modified filler necks to avoid splash-out, I searched at one point to see what neck is specified when a 22 gallon conversion tank is put in a '69 and did not find a firm answer. If the taillight panels put the neck in the exact same spot, then obviously you need a '70 neck in a '69 with the 22 gallon tank. But if this is NOT the case either a special conversion neck is required or you have to modify one yourself. I thought I had a 69 & 70 neck side by side picture but could not find one. I will take one when I'm back home Wednesday night if still needed. Doug Quote Share this post Link to post Share on other sites
RPM 1,190 Report post Posted October 23, 2019 When I installed a 1970 22 gal tank, I used a 70 filler tube. Don't know the difference of the 70 tank and yours though. 1 stangs-R-me reacted to this Quote Share this post Link to post Share on other sites
Darkman 2 Report post Posted October 24, 2019 I am planning on using EFI on my 69 Mach 1 restomod. I want to use the system where you dont have to run a return from the front and it's all handled at the tank. Holley makes the tank and EFI system like that. Is the Tanks Inc. tank better or cheaper than the Holley EFI tank? Quote Share this post Link to post Share on other sites

I took 2 pics of '69 & '70 necks side by side and I think the '70 neck will line up with your tank as RPM said ... 1 RPM reacted to this Quote Share this post Link to post Share on other sites
aslanefe 333 Report post Posted October 27, 2019 Looking at stangs-R-me's pictures, 1970 filler neck will work for you. Quote Share this post Link to post Share on other sites
