Gas Cap

[Railroad]

I searched, but did not find, what I thought was there.
I was fitting parts onto the body, now that I have it close to being positioned on the chassis.
The gas cap, Stant brand, would not lock on the filler neck. The 3 tabs are too tall to go upon the shoulders inside the neck. After a little dressing of the plastic tabs, they cap twist out of the slots onto the shoulders.
Surprise the shoulders are not ramped.
The cap is snuggly in place, but I thought would tighten or hit a stop, neither happens.
What are some options on this?

For quite some time F5 was providing the wrong cap to go inside the housing; sounds like maybe you got one of those. You want a Motorcraft-FC961 cap (https://www.amazon.com/Motorcraft-FC961-Fuel-Push-Style/dp/B000C5FL84). I've lost the original thread, so I can't credit the builder who figured this out. Whoever you are, thanks!

Thanks for the info, sure makes it easier.
I think I will call FFR, no need in me spending $20.

Count me in on the same problem. Initially, the cap refused to come out and I ended up using pliers to pull up on it. Now the cap never gets to the clicks. Thanks for the part number to the motorcraft cap.

I thought I was doing something wrong. Mine will click and lock, but comes loose. When you try to turn it to open it, it doesn't move. After nearly breaking it, I accidently discovered I could simply pull it straight out like it wasn't closed. New cap ordered! Thanks for the info.

... When you try to turn it to open it, it doesn't move...

I can confirm this! :rolleyes:

I talked to Jay at FFR about the cap. I have the 10832 Stant which cross ref with the Ford number posted. Jay checked their alum filler with the same cap I have. Naturally his fit, but he did find one with the rubber gasket not in place, which would increase the distance in question.
While I had him on the phone, I mentioned the metal where the tabs ride is flat. No ramps or stops.
I filed the plastic tabs down and got the cap to twist. There is some resistance with the cap in this position, but if I keep twisting the tabs will line up to remove the cap.
I do not understand the design.

I receive the new Motocraft gas cap from the link in post #2 above and after removing the tether, it is a perfect fit that actually works! Thanks for the tip.

Mine did too.

Same here. RockAuto has both locking and regular.
