I'm looking to replace the gas tank in my 35 Ford and want a locking gas cap.  I checked with Tanks Inc. and their tank (neck) does not have a locking cap capability.  Does anyone make a replacement tank that does?  Alternatively, does anyone know of a locking gas cap maker who makes a locking cap for a stock 35 tank?

well its the FILLER neck that screws into the side neck of the tank where the cap mounts...

these are the part numbers for the stock replacement cap..

CST/Fuel Cap  Part Number: 6025 Stant Part #: 10625

what's interesting.. the 6025 cap shows a od less the tabs of 1.831.  and the cap OD of 2.843.. ..

this is the filler neck..

48 9034 Lrg

you can see in this image that the thick part is actually a threaded sleeve that threads in and the flair seats in the tank...

sure looks like 1 7/8 ID opening..

as to what cap to use.. since the original is NON VENTED..

the replacement locking cap needs to be non vented.. so you don't end up with drips down your paint..

let me give you a list of various gas caps that are LOCKING and NON vented..

CST    5784
CST    5785

you will probably want to look at the 2 below... as they are more current..
CST    5794
CST    5796

with a chain type of muffler cutter.. you should be able to reverse search out the applications..

then visit a junk yard chain cut off the filler neck tube...   get it back to your shop and carefully cut the outside of the neck off the tube.. leaving a flange with gas cap threads on the you can epoxy this in place on your existing filler neck...

somebody who is creative.. might buy a second cap..  create a wooden plug that could be chucked up in a lathe...  then spin a cover for it so it would have the nice round hole for the key way.. but fit over the new cap nicely.. some decent adhesive.. and its installed..  one could even knurl the outside diameter like the stock cap...

i never advise soldering on fuel tanks..  but epoxy will work..   if your filler neck is not frozen in place or you have a new one to install... you might use some low melting point silver solder to hold the custom cut threaded filler neck end on your push and twist filler neck..

i keep forgetting to call spectra premium as they do gas tanks and filler necks if they had ever created just a flat flanged threaded filler neck repair section... so i could epoxy it in to push and twist latch type filler necks..

just to help.. the 5794 fits camaro and firebird applications from 82 to 89...  but the thread size is the same as the 5791 ...

its 1 5/8 thread...   so you should not have an issue finding a filler neck as a donor..

look  up a 5791 gas cap  at the oreilly parts site.. there is a tab there to show compatability... its the same size thread.. but vented cap... so you could use the 5794 as its shown for 82 to 89 camaro and firebird applications.. and those are HARD to get at the filler neck to donate them to your cause..
the same size 5791 fits hundreds of applications from 75 up to almost current models i saw some as late a 2008...

so look up the apps for the 5791...  it will broaden your search to all corners of the junk yards..

Did you try checking with Rock Valley Antique Auto Parts? They make and rebuild gas tanks for the majority of old Fords and Chevys. They advertise in Street Rodder and I was able to get a new stainless tank with sending unit for my 37 Stovebolt.
