Stock tank cap.

Seen several cars I have seen have paint damage from a leaking fuel cap. Add a home with a steep driveway and on a hillside and the problem is worse.

I've shimmed out the cork gasket and one cap on one car has been refitted when the cap was re chromed.

I've several Home Depot esque remedies in mind. Other ideas out there?

I replaced the original seal with the rubber seal from a Big Healey gas cap. about twice as thick as the original seal and more flexible... worked for me!
 
Thanks Sean, I can park in the driveway or be traversing it and get seepage. Plus parking on an incline or they say listing to starboard plus the expansion in the sun makes a mess.

In the Falcon and Mustang cars we abandoned the stock cap and put one above the tank in the trunk.

I had the same problem if I had a full tank. once I replaced the seal with the rubber one, the problem was solved!
 
I have a Sunbeam Specialties one some place. Be interesting to know how it compares.
 
The easy solution is don't fill the tank to the brim. You'll be making stops at a C store every couple hours if your wife is along so pump some gas while waiting for her. There is a factor in the fuel business called "net gallons versus gross gallons or temperature corrected gallons". If you're pumping gas from under ground tanks you'll find the temperature of the gas to be lower than after it mixes with the warmer gas already in the car tank. Fuel does expand in hot temps so if you pump 10 gallons into your tank and don't leave room for the expansion It tends to go where ever it may after expansion which could mean down the fender.

Thank for the every day advice. We have CARB compliant gas cans here in Calunicornia. They turn into a plastic balloon when left on the sun . My car designer buddy said that more gas is spilled yearly then the Exxon Valdez oil spill. Since I'm no relation to Captain Hazelwood and I don't want my ol paint further ruined I'm working on it.

As mentioned before it's only a problem if I'm going on a long trip and want to get a long way between stops. Or If I'm on my driveway or my hilly neighborhood turning the car on a twisty road or parking on the incline.

So back to the problem at hand. The cork gasket looks to be captive under the metal here. I have a Home Depot solution so I can drive the car but it's really not very elegant in any manner, but it's not able to be seen underneath the chrome cover.

Well, that particular cork gasket appears to be overly "experienced". As I said befoah , Rick's rubber replacement works fine.
 
You can always turn the gasket over, assuming you can get it out in one piece... besides, the excuse that your significant female partner needs to stop every 2 hours might be viewed with some disdain... Unless, of course, you'd like to be an "incel" for the rest of your remaining life. I know that I'd NEVER say anything like that to my wife.... EVEN if she actually needed to stop every 2 hours (which she doesn't). I have this voice ringing in my ears... "You should have peed before we left"

The replacement rubber gasket is the ideal solution.

And Warren.... I thought it was Californication for people who were Californicators.......
 
The SS one was about the same size as the cork original one, which seems to be underneath the pressed on part. So the choice must be cut around the circumference of the metal to remove the cork slap a rubber over it. Not like I'm concerned about stock ;)

I will stretch the spring out some, prior to the installation.

Never watched that California series.

The cork being brittle just breaks out. The rubber replacement, being rubber, stretches over the metal flange and nests under it nicely.

Don't ASSUME! My wife suffers from RA and has to get out of the car and walk around in order to relieve the stiffness in the joints.

I've seen many of the corks that have been painted over many times.
 
Wow...
It looked like the cork was captive. Mine was really stuck on there well it took a little bit of soaking and loosening up with good old WD-40. I didn't want to bust it out into pieces so I can make a nice copy I also didn't want to bust it into pieces so I could flip it over, per prior suggestion and habit. It looks like your standard Honda vintage gas cap cork. It had a loose edge and a remedy that worked a little bit was a simple light piece of nylon thread tied tightly underneath it to space it out a little further. I do my best not to destroy original parts even when they come off my personalized sliding rapidly towards modified car.

I had the cap off the car except for the pretty chrome lid. Plus I always hated my nice tight garage smelling like several tanks of gasoline in the motorcycles in the cars. I don't think it's completely appropriate to make relationship comments so I'll just say eau de barras isn't well received. A plastic bag under the cap is a poor substitute for a charcoal canister evaporative controls on a car or motorcycle.

I left my original cork gasket on the cap since it was all intact and not cracked but was hard I them put the new cork gasket on top of it. It works well and makes the cap nice and snug
