Aftermarket gas tanks will only accomodate those junk aftermarket fuel senders. Has anybody enlarged the opening a 1/4" enabling the use of the original King Seeley fuel sender?

It depends on what year tank whether or not you can enlarge the hole. Sometime back I got a Drake tank and it had holes for both senders. I have no idea if that is the case now or not. If they say the tank uses the Drake sender I believe the bolt pattern for the sender is the same as the original sender. If that is the case you should be able to enlarge the hole out as far as the mounting ring surface. Have them send you a photo of the sender mounting area. You should be able to see if it can be enlarged or not before you buy one.

I have an aftermarket tank on my 42. The original sender was able to be installed with no problem. My problem is that I don't remember where it came from but probably Drake.

In 2005, Drake started phasing out his tanks that could take either sending unit. All tanks made after 2005 have the smaller opening and the 5 hole flange. The original sending units have a 6 hole flange. If your tank cannot be repaired, you will have to save the flange from it and have it soldered to your new tank after removing the flange on the new tank. My original Mercury tank has the flange soldered in place from the factory. A radiator shop should be able to remove the flange on the Ford tank. Rock Valley Antique Auto Parts may be able to make you a tank that will accept the original sending unit. Here is a link to their website: http://www.rockvalleyantiqueautoparts.com/catalog.htm Tom

You got that right about junk aftermarket senders!! I purchased an aftermarket tank from Tanks Inc. and their "suggested " sender which is way out to lunch!!! The one recommended for my 50 Mercury is for early Ford and Mopar 10-75 ohms. I bought this back in 2012 but saw much chirping about how bad these senders were and put this saga off until a week ago. Because of all of the complaints I wired up my aftermarket sender to my very good stock properly functioning system and moved the pivot on the aftermarket sender for empty, 1/4,1/2,34,full and in each of these positions measured with a digital multimeter. What a joke!! 10-75 ohms recommended but in reality 12-31 ohms needed. 10-30 is listed for senders recommended for GM and this would have been a better choice. I threw the looser sender in the new tank with the arm as long as possible ignoring the instructions telling me to cut that arm fairly short. I'm way out to lunch on the range so why would I cut it short? A shorter arm will rise more and drop more in my fairly long tank so I left it long so it would rotate the sender less and cut the arm just sort enough to clear the end of the tank or two inches off of new. Then I threw it in the unmounted tank and measured when empty. Resistance wasn't proper so I gently and neatly bent the arm to limit how far the arm dropped until it was proper for empty as measured at the beginning. Then I flipped the tank upside down and checked again and the resistance would result in an over pegged gauge so I limited the full travel of the arm by the adjustable tang or tab on the sender to limit the excessive full travel. Then I installed the tank and carefully measured out enough for a precise 1/4 tank and resulted in a half tank. I then pulled the sender and straightened the arm very slightly which gave me between a third and half requiring me to slide the sender up the rail its mounted to. Finally after 3 hours of fumbling around I have it fairly decent in all levels except very full is slightly below the full mark which means I will have to tweak the tab allowing the full limit to show more. Simply lousy and because it is 10-75 means out of that range is very small for the actual 12-31 ohms. I chirped to Tanks about the 5 hole only decision they made when 6 hole aftermarket senders are available as a direct replacement and also what happens if I have a very good original or NOS sender?? Both 5 and 6 hole patterns could have been used. Also these stupid senders start varying as you drive showing a tank almost empty and shoving a stick down the filler indicates 1/2!full! Shut off the ignition for a few minutes and restart and we have a 1/2 tank. Inaccurate garbage aftermarket probably offshore junk. And top this off with how the fitting in the tank was 3/8 pipe when it should be 5/16 or dash 5 inverted flare and then the running around started to find a 3/8 pipe to 5/16 inverted flare adaptor.

If you are building a driver, rather than a restoration, consider a plastic tank. I installed one in my '47 convertible over 20 years ago, and it has been trouble free. It will accept either type of sender, and only requires a separate ground wire to the sender flange.
