Are you tired of dealing with the possibility of splash-out when filling your classic Mustang with fuel ?? I was certainly fed up with gas pump drama with my 1969 and searched the internet for solutions a few times over the years and basically found nothing.

In the fear of splash-out onto my bumper, license plate, and the painted surfaces around & below the filler neck I would squat down with my ear near the pump nozzle and listen to the fuel going in. Listening carefully, you can hear the sound change as the tank gets full and the goal was to release the lever in time to avoid splash-out. This was always a nerve-wracking routine, especially if there were other noises (traffic, etc.) to distract concentration so I dreaded the experience at each fill up. I've owned this car for 38 years and this problem has been a part of fueling since the late 80's when leaded gas disappeared. The leaded nozzles were designed to shut-off in an open filler neck, so my guess is they were more sensitive than unleaded nozzles. However a defective leaded nozzle could cause splash out too, so it was still a crap shoot even prior to unleaded gas becoming the only option.

Anyway, I finally found someone who installed an off-the-shelf "unleaded fuel insert" that was a viable solution (credit goes out to forum member Mach1 Driver). His method however required major neck modification ... including cutting ... which was not appealing to me. So I ordered a couple of the same inserts to play with hoping to come up with an easier solution. After some brainstorming, I ended up adapting the insert to fit up the neck with minimal modification to the neck itself ... far simpler.

I've now had it in my car for over a year and it is by far the most functional mod I've ever done. Like a modern car I can now just put the nozzle in, set the nozzle flow on the 1st or middle notch, let go, stand back, and wait for the nozzle to shut-off on it's own like it is supposed to do ... with ZERO SPLASH-OUT.

To be able to finally fuel up my classic Mustang without any drama and "hands-free" is pure satisfaction.

I then realized there are 9 different 1965 thru 1970 Mustang Fuel Filler Neck variations available, so I bought a sample of each and figured out how to adapt the insert to each one. There are both painted/powder coated and zinc plated necks and both styles are available for all years but 1970 ... which so far I've only found painted/powder-coated versions.

I sell both complete new necks with the insert installed as well as insert kits with instructions for your own installation. If you want to do your own install I strongly recommend using a new neck, and I show all the necks that I know work on page 2 of my Price Sheet (page 2 of Tool List has even more details).

See attached PDF files for all the details including pricing and contact info.

I'll vouch!!!!!!!!!! I personally bought one of these from Stangs-R-Me a while back. Finally got my car on the road and went to fill up.
Pump in, Squeeze and lock, Clicked when full. No splash, no stink, Great product!

How about a filler neck for the 65/6 with the later 20 gallon tanks?

I don't MAKE the actual necks, so some parts vendor/mfr. would have to see the need for such a neck and make it so I could buy it and modify it.

The likely reason it is NOT made is the industry has mostly latched onto the 1970 22 Gallon tank as the ideal Mustang gas tank and YES there are necks for this 22 gal tank in a '65-66, '67-68, and '69.

i just used the 22 gal conversion neck from npd on a 20 gal tank in my '65 - fit fine - i ended up with a nearly new 20 gal tank/pickup and figured id give it a try.....
That is great to know, really appreciate hearing this as I can now share this info with potential buyers. Guessing you needed a bit extra hose length too, but they cut the repros a bit longer so maybe there is a long enough one that can be used or cut to fit. I had to cut about 1-3/8" off of the new hose I installed in my '69 to match the original's length.

Did you possibly take a picture when installing to show how it fit / lined up or could you take a side view picture as installed now ??

Thanks,

Doug

I have updated my Price List and it now states the '65-66 Conversion Neck can be used on '65-66 with 20 Gallon Tank and 5" long hose.

Thanks again goes out to "ididntdoit" for figuring this out !!
